This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used. Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used. Flex mode. This mode provides the most flexible performance characteristics. The bottommost DRAM memory (the memory that is lowest within the system memory map) is mapped to dual channel operation; the topmost DRAM memory (the memory that is nearest to the 8 GB address space limit), if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To use flex mode, it is necessary to populate both channels. For information about… Refer to: Memory Configuration Examples http://www.intel.com/support/motherboards/desktop/sb/cs011965.htm Product Description Figure 3 illustrates the memory channel and DIMM configuration. Figure 3. Memory Channel and DIMM Configuration NOTE For best memory performance always install memory in the blue DIMM sockets if installing only two DIMMs on your board. Populate DIMM sockets in the order in which they are numbered. 21 Intel Desktop Board DQ77MK Technical Product Specification Intel® Q77 Express Chipset 1.5 Intel Q77 Express Chipset with Intel Flexible Display Interconnect (Intel FDI) and Direct Media Interface (DMI) interconnect provides interfaces to the processor and the display, USB, SATA, LPC, LAN, and PCI Express interfaces.

Dependent on the standby power consumption of wake-up devices used in the system. 39 Intel Desktop Board DQ77MK Technical Product Specification 1.12.1.2 Wake-up Devices and Events Table 12 lists the devices or specific events that can wake the computer from specific states. Table 12. Wake-up Devices and Events These devices/events can wake up the computer… …from this state Power switch S3, S4, S5 RTC alarm S3, S4, S5 (Note) LAN S3, S4, S5 (Note) USB S3 PME# signal S3, S4, S5 (Note) WAKE# S3, S4, S5 (Note) Serial port S3 (Note) Note: S4 implies operating system support only. NOTE The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. 1.12.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The board provides several power management hardware features, including: • • • • • • • • • • Power connector Fan headers LAN wake capabilities Instantly Available PC technology Wake from USB Power Management Event signal (PME#) wake-up support PCI Express WAKE# signal support Wake from serial port Wake from S5 +5 V Standby Power Indicator LED LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. NOTE The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support. 40 Product Description 1.12.2.1 Power Connector ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu. For information about Refer to The location of the main power connector Figure 11, page 49 The signal names of the main power connector Table 29, page 57 1.12.2.2 Fan Headers The function/operation of the fan headers is as follows: • • • • • • The fans are on when the board is in the S0 state The fans are off when the board is off or in the S3, S4, or S5 state Each fan header is wired to a fan tachometer input of the hardware monitoring and fan control ASIC All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed All fan headers have a +12 V DC connection The fan headers are controlled by Pulse Width Modulation For information about Refer to The location of the fan headers Figure 11, page 49 The location of the fan headers and sensors for thermal monitoring Figure 6, page 32 1.12.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in the following ways: • • • • The PCI Express WAKE# signal By Ping Magic Packet The onboard LAN subsystem 41 Intel Desktop Board DQ77MK Technical Product Specification 1.12.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Instantly Available PC technology can damage the power supply. Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 12 on page 40 lists the devices and events that can wake the computer from the S3 state. The board supports the PCI Bus Power Management Interface Specification. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI Express add-in cards and drivers. 1.12.2.5 Wake from USB USB bus activity wakes the computer from an ACPI S3 state. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.12.2.6 PME# Signal Wake-up Support When the PME# signal on the Conventional PCI bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state (with Wake on PME enabled in the BIOS). 1.12.2.7 WAKE# Signal Wake-up Support When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state. 1.12.2.8 Wake from Serial Port Serial port activity wakes the computer from an ACPI S3 state. 1.12.2.9 Wake from S5 When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an ACPI S5 state. 42 Product Description 1.12.2.10 +5 V Standby Power Indicator LED The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 8 shows the location of the standby power LED. CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices. Figure 8. Location of the Standby Power LED 43 Intel Desktop Board DQ77MK Technical Product Specification 44 2 Technical Reference 2.1 Memory Resources 2.1.1 Addressable Memory The board utilizes 32 GB of addressable system memory. Typically the address space that is allocated for Conventional PCI bus add-in cards, PCI Express configuration space, BIOS (SPI Flash device), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 32 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following: • • • • • • BIOS/SPI Flash device (96 Mb) Local APIC (19 MB) Direct Media Interface (40 MB) PCI Express configuration space (256 MB) PCH base address registers PCI Express ports (up to 256 MB) Memory-mapped I/O that is dynamically allocated for Conventional PCI and PCI Express add-in cards (256 MB) The board provides the capability to reclaim the physical memory overlapped by the memory mapped I/O logical address space. The board remaps physical memory from the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just above the 4 GB boundary. Figure 9 shows a schematic of the system memory map. All installed system memory can be used when there is no overlap of system addresses. 45 Intel Desktop Board DQ77MK Technical Product Specification Figure 9.

The other internal connectors and headers are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors or headers to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. Furthermore, improper connection of USB or 1394a header single wire connectors may eventually overload the overcurrent protection and cause damage to the board. This section describes the board’s connectors. The connectors can be divided into these groups: • • Back panel I/O connectors Component-side connectors and headers (see page 49) 47 Intel Desktop Board DQ77MK Technical Product Specification 2.2.1 Back Panel Connectors Figure 10 shows the location of the back panel connectors for the board.

SMBus signals are routed to the Conventional PCI bus connector. This enables Conventional PCI bus add-in boards with SMBus support to access sensor data on the desktop board. The specific SMBus signals are as follows: The SMBus clock line is connected to pin A40. The SMBus data line is connected to pin A41. NOTE PCI Express 3.0 is only supported by 3rd generation Intel Core processor family processors. 56 Technical Reference 2.2.2.3 Power Supply Connectors The board has the following power supply connectors: • • Main power – a 2 x 12 connector. This connector is compatible with 2 x 10 connectors previously used on Intel Desktop boards. The board supports the use of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When using a power supply with a 2 x 10 main power cable, attach that cable to the main power connector, leaving pins 11, 12, 23, and 24 unconnected. Processor core power – a 2 x 2 connector. This connector provides power directly to the processor voltage regulator and must always be used. Failure to do so will prevent the board from booting. Table 28.

Connection Diagram for Front Panel USB 2.0 Connectors 60 Technical Reference 2.3 Jumper Block CAUTION Do not move the jumper with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged. Figure 14 shows the location of the jumper block. The 3-pin jumper block determines the BIOS Setup program’s mode. Table 34 describes the jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to configure mode and the computer is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match. Figure 14. Location of the Jumper Block Table 34. BIOS Setup Configuration Jumper Settings Function/Mode Jumper Setting Configuration Normal 1-2 The BIOS uses current configuration information and passwords for booting. Configure 2-3 After the POST runs, Setup runs automatically. The maintenance menu is displayed. Note that this Configure mode is the only way to clear the BIOS/CMOS settings. Press F9 (restore defaults) while in Configure mode to restore the BIOS/CMOS settings to their default values. Recovery None The BIOS attempts to recover the BIOS configuration. A recovery CD or flash drive is required. 61 Intel Desktop Board DQ77MK Technical Product Specification Intel® Management Engine BIOS Extension (Intel® MEBX) Reset Header 2.4 The Intel® MEBX reset header (see Figure 15) allows you to reset the Intel ME configuration to the factory defaults. Momentarily shorting pins 1 and 2 with a jumper (not supplied) will accomplish the following: • • Return all Intel ME parameters to their default values. Reset the Intel MEBX password to the default value (admin). CAUTION Always turn off the power and unplug the power cord from the computer before installing an MEBX reset jumper. The jumper must be removed before reapplying power. The system must be allowed to reach end of POST before reset is complete. Otherwise, the board could be damaged. NOTE After using the MEBX Reset, a “CMOS battery failure” warning will occur during the next POST. This is expected and does not indicate a component failure. Figure 15.

Board Dimensions 63 Intel Desktop Board DQ77MK Technical Product Specification 2.6 Electrical Considerations 2.6.1 Power Supply Considerations CAUTION The +5 V standby line from the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the indicated parameters of the ATX form factor specification. • • • • The potential relation between 3.3 V DC and +5 V DC power rails The current capability of the +5 VSB line All timing parameters All voltage tolerances For example, for a high power system consisting of a supported 95 W processor (see Section 1.3 on page 16 for a list of supported processors), 4 GB DDR3 RAM, one high end video card, one hard disk drive, one optical drive, and all board peripherals enabled, the minimum recommended power supply is 460 W.

Connecting the processor fan to a chassis fan header may result in onboard component damage that will halt fan operation. Table 38 lists the current capability of the fan headers. Table 38. Fan Header Current Capability Fan Header Maximum Available Current Processor fan 2.0 A Front chassis fan 1.5 A Rear chassis fan 1.5 A 2.6.4 Add-in Board Considerations The board is designed to provide 2 A (average) of current for each add-in board from the +5 V rail. The total +5 V current draw for add-in boards for a fully loaded board (all three expansion slots filled) must not exceed the system’s power supply +5 V maximum current or 14 A in total. 2.7 Thermal Considerations CAUTION A chassis with a maximum internal ambient temperature of 38 oC at the processor fan inlet is a requirement. Use a processor heat sink that provides omni-directional airflow to maintain required airflow across the processor voltage regulator area. CAUTION Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board. For a list of chassis that have been tested with Intel desktop boards please refer to the following website: http://www3.intel.com/cd/channel/reseller/asmo-na/eng/tech_reference/53211.htm All responsibility for determining the adequacy of any thermal or system design remains solely with the reader. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance. 65 Intel Desktop Board DQ77MK Technical Product Specification CAUTION Ensure that the ambient temperature does not exceed the board’s maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.9. CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area (shown in Figure 17) can reach a temperature of up to 120 oC in an open chassis. Figure 17 shows the locations of the localized high temperature zones. Item Description A B C Processor voltage regulator area Processor Intel Q77 Express Chipset Figure 17. Localized High Temperature Zones 66 Technical Reference Table 39 provides maximum case temperatures for the components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board. Table 39. Thermal Considerations for Components Component Maximum Case Temperature Processor For processor case temperature, see processor datasheets and processor specification updates Intel Q77 Express Chipset 104 oC To ensure functionality and reliability, the component is specified for proper operation when Case Temperature is maintained at or below the maximum temperature listed in Table 39. This is a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified as the maximum sustainable power to be dissipated by the components). When the component is dissipating less than TDP, the case temperature should be below the Maximum Case Temperature. The surface temperature at the geometric center of the component corresponds to Case Temperature. It is important to note that the temperature measurement in the system BIOS is a value reported by embedded thermal sensors in the components and does not directly correspond to the Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is Tcontrol. Table 40. Tcontrol Values for Components Component Tcontrol Processor For processor case temperature, see processor datasheets and processor specification updates Intel Q77 Express Chipset 104 oC For information about Refer to Processor datasheets and specification updates Section 1.2, page 16 Intel Q77 Express Chipset http://www.intel.com/products/desktop/ chipsets/ 67 Intel Desktop Board DQ77MK Technical Product Specification 2.8 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using parts count method.

The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as MKQ7710H.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing thekey after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. The menu bar is shown below. Maintenance Main Configuration Performance Security Power Boot Exit NOTE The maintenance menu is displayed only when the board is in configure mode. Section 2.3 on page 61 shows how to put the board in configure mode. 69 Intel Desktop Board DQ77MK Technical Product Specification Table 42 lists the BIOS Setup program menu features. Table 42.

PCI Express devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI Express cards without having to configure the system. When a user turns on the system after adding a PCI Express card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. 70 Overview of BIOS Features 3.4 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: • • • • BIOS data, such as the BIOS revision level Fixed-system data, such as peripherals, serial numbers, and asset tags Resource data, such as memory size, cache size, and processor speed Dynamic data, such as event detection and error logging Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. Additional board information can be found in the BIOS under the Additional Information header under the Main BIOS page. 3.5 Legacy USB Support Legacy USB support enables USB devices to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. 7. Additional USB legacy feature options can be access by using Intel® Integrator Toolkit. 71 Intel Desktop Board DQ77MK Technical Product Specification To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions. 3.6 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: • • Intel® Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web. Intel® Flash Memory Update Utility, which requires booting from DOS. Using this utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM. Both utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS. NOTE Review the instructions distributed with the upgrade utility before attempting a BIOS update. For information about Refer to BIOS update utilities http://support.intel.com/support/motherboards/desktop/sb /CS-022312.htm. 3.6.1 Language Support The BIOS Setup program and help messages are supported in US English. Check the Intel web site for support. 72 Overview of BIOS Features 3.6.2 Custom Splash Screen During POST, an Intel® splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. The Intel Integrator’s Toolkit that is available from Intel can be used to create a custom splash screen. NOTE If you add a custom splash screen, it will share space with the Intel branded logo. For information about Refer to Intel Integrator Toolkit http://developer.intel.com/design/motherbd/software/itk/ ® Additional Intel software tools 3.7 http://developer.intel.com/design/motherbd/software.htm BIOS Recovery It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 44 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable. Table 44. Acceptable Drives/Media Types for BIOS Recovery Media Type Can be used for BIOS recovery? CD-ROM drive connected to the SATA interface Yes USB removable drive (a USB Flash Drive, for example) Yes USB diskette drive (with a 1.44 MB diskette) No USB hard disk drive No For information about Refer to BIOS recovery http://www.intel.com/support/motherboards/desktop/sb/ cs-023360.htm 73 Intel Desktop Board DQ77MK Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive, removable drive, or the network. The default setting is for the optical drive to be the first boot device, the hard drive second, removable drive third, and the network fourth. 3.8.1 Optical Drive Boot Booting from the optical drive is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, the optical drive is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the optical drive, the system will attempt to boot from the next defined drive. 3.8.2 Network Boot The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full. 3.8.3 Booting Without Attached Devices For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: • • • Video adapter Keyboard Mouse 3.8.4 Changing the Default Boot Device During POST Pressing the key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices. Table 45 lists the boot device menu options. Table 45. Boot Device Menu Options 74 Boot Device Menu Function Keys Description <↑> or <↓> Selects a default boot device Exits the menu, and boots from the selected device Exits the menu and boots according to the boot priority defined through BIOS setup Overview of BIOS Features 3.9 Adjusting Boot Speed These factors affect system boot speed: • • • Selecting and configuring peripherals properly Optimized BIOS boot parameters Enabling the Fast Boot feature 3.9.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • • • • Choose a hard drive with parameters such as “power-up to data ready” in less than eight seconds that minimizes hard drive startup delays. Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time. Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process. Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly. 3.9.2 BIOS Boot Optimizations Use of the following BIOS Setup program settings reduces the POST execution time. • • • In the Boot menu, enable the settings for Fast Boot. This option will allow BIOS to skip through various stages of POST and boot quickly to the last detected boot device. In the Boot Menu, set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time. NOTE It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from zero to 30 seconds by 5 second increments (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program). 75 Intel Desktop Board DQ77MK Technical Product Specification 3.10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • • • • • • • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode. The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is the user mode. If only the supervisor password is set, pressing the key at the password prompt of the BIOS Setup program allows the user restricted access to Setup. If both the supervisor and user passwords are set, users can enter either the supervisor password or the user password to access Setup. Users have access to Setup respective to which password is entered. Setting the user password restricts who can boot the computer. The password prompt will be displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer. For enhanced security, use different passwords for the supervisor and user passwords. Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 16 characters in length. Table 46 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen. Table 46. Supervisor and User Password Functions Password During Boot None None None Can change a limited number of options Supervisor Password Supervisor None N/A Can change all options Enter Password Clear User Password User User Can change all options Can change a limited number of options Supervisor Password Enter Password Supervisor or user Supervisor or user Supervisor Mode User Mode Neither Can change all options (Note) Can change all options (Note) Supervisor only Can change all options User only Supervisor and user set Note: 76 Setup Options Password to Enter Setup Password Set If no password is set, any user can change all Setup options.

CMOS memory may have been corrupted. Run Setup to reset values. Memory Size Decreased Memory size has decreased since the last boot. If no memory was removed, then memory may be bad. No Boot Device Available System did not find a device to boot. Error Messages and Beep Codes 4.5 Port 80h Power On Self Test (POST) Codes During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST codes on a medium such as a seven-segment display, requires a POST card that can interface with the Low Pin Count (LPC) Debug header or a POST card that can be installed in one of the Conventional PCI connectors. Refer to the location of the LPC Debug header in Figure 1. The following tables provide information about the POST codes generated by the BIOS: • • • Table 50 lists the Port 80h POST code ranges Table 51 lists the Port 80h POST codes themselves Table 52 lists the Port 80h POST sequence NOTE In the tables listed above, all POST codes and range values are listed in hexadecimal.
