X
with vPro Technology part of the Intel 2008 Stable Image Platform Program (SIPP) designed to ensure the
stability promise inherent in the value proposition of the HP Compaq dc7900
Series business desktop, thus making these model the most stable, secure, and
manageable platforms available to enterprises today.
The 2008 SIPP processors are:
Core 2 Duo E8400, E8500, E8600
Core 2 Quad Q9400, Q9550, Q9650
Intel's Core 2 Processor with vPro Technology suite of features includes:
Intel Active Management Technology
an advanced set of remote management features and functionality which
provides network administrators the latest and most effective tools to remotely
discover, heal, and protect networked client systems regardless of the
system's health or power state. Intel Active Management Technology
includes all features described as part of Intel Standard Manageability plus
the following advanced management functions:
Fast Call for Help – a client inside or outside the firewall may initiate
a call for help via BIOS screen, periodic connections, or alert
triggered connection
Remote Scheduled Maintenance – pre-schedule when the PC
connects to the IT or service provider console for maintenance.
Remote PCs can get required patches, be inventoried, etc by
connecting to their IT console or Service Provider when it's convenient
Remote Alerts – automatically alert IT or service provider if issues arise
Access Monitor – Provides oversight into Intel® AMT actions to
support security requirements
Microsoft NAP Support
Allows Intel Active Management Technology to gain access to a Microsoft
NAP enabled 802.1x network OOB to enable OOB SW updates,
inventories, remote diagnostics, etc. NAP is a new platform and solution that
controls access to network resources based on a client computer's identity
and compliance with corporate governance policy. NAP allows network
administrators to define granular levels of network access based on who a
client is, the groups to which the client belongs, and the degree to which
that client is compliant with corporate governance policy. If a client is not
compliant, NAP provides a mechanism to automatically bring the client back
into compliance and then dynamically increase its level of network access.
When a client attempts to access the network or communicate on the
network, it must present its system health state or proof of health compliance.

QuickSpecs

HP Compaq dc7900 Business PC

Standard Features and Configurable Components
If a client cannot prove it is compliant with system health requirements (for
example, that it has the latest operating system and antivirus updates
installed), its access to the network or communication on the network can be
limited to a restricted network containing server resources so that health
compliance issues can be remedied. After the updates are installed, the
client requests access to the network or attempts the communication again. If
compliant, the client is granted unlimited access to the network or the
communication is allowed.

Memory

DDR2 SYNCH DRAM NON-ECC MEMORY
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied sizes.
This chart does not represent all possible memory configurations. The HP Compaq dc7900 business
desktop supports non-ECC DDR2 PC2-5300 (667-MHz) and PC2-6400 (800-MHz) memory.
CAUTION: You must shut down the computer and disconnect the power cord before adding or removing
memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as
long as the computer is plugged in to an active AC outlet. Adding or removing memory modules while
voltage is present may cause irreparable damage to the memory modules or system board.
HP recommends dual-channel symmetric configurations for maximum performance.
For best performance, add the same amount of total memory to each channel and do not mix speeds. For
dual-channel symmetric performance, the total amount of memory in each channel must be equal. If
speeds are mixed, speed will default to the slowest DIMM.

RAID

Redundant Array of Independent Drives
Flexible implementation:
DriveLock is supported while in RAID mode. Users can manage DriveLock password from within
F10 Setup. Locked drives will be displayed as such in the RAID option ROM interface.
Hard drive information can be viewed within F10 Setup while in RAID mode. Previously, the hard
drives will not appear in Drive Configuration when switching to RAID mode.
DPS Self Test can be executed on physical hard drives while in RAID mode.
The RAID Setup Utility (accessed through CTRL-I) can be protected by the F10 Setup password.
NOTE: RAID 1 is the only RAID configuration that HP Compaq dc7900 Business PC products offer as
factory configurations. The pre-configured systems:
Are only available on the CMT and SFF form factors. The USDT does not support RAID as it does
not allow for more than one hard disk drive.
Are complete RAID systems and have both drives installed.
Have the necessary Option ROM configuration.
Are pre-loaded and pre-installed with all required Intel software.
Include a preinstalled operating system that is mirrored mode out of the box.
Please refer to the HP White Paper titled "Advanced Host Controller Interface (AHCI) and Redundant
Array of Independent Disks (RAID) on HP Compaq dc7900 Business PCs" at http://www.hp.com for
more information and instructions.

General Unit Operating Guidelines

Ultra-slim Desktop

Small Form Factor

Convertible Minitower

Keep the computer away from excessive moisture, direct moisture and the extremes of heat and cold, to ensure that unit is
operated within the specified operating range.
Leave a 10.2 cm (4 in) clearance on all vented sides of the computer to permit the required airflow.
Never restrict airflow into the computer by blocking any vents or air intakes.
Do not stack computers on top of each other or place computers so near each other that they are subject to each other's recirculated or preheated air.
Occasionally clean the air vents on the front, back, and any other vented side of the computer. Lint, dust and other foreign
matter can block the vents and limit the airflow.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure,
and the same operating guidelines listed above will still apply.

ROM BIOS Information
Key features of the HP BIOS in the dc7900 include:
Deployment and manageability – HP BIOS provides several technologies that help integrate the HP Business desktop computer
into the enterprise, such as PXE, remote configuration, remote control, and F10 Setup support for 12 languages.
Select models feature either Intel Standard Manageability or Core 2 processor with vPro Technology.
Stability – HP BIOS supports the HP stable product roadmap by releasing only critical BIOS changes to the factory and
advanced change notification.
Security – HP BIOS Configuration for ProtectTools offers a robust and flexible set of security features to help the system
administrator secure their systems from removal of sensitive data, and help prevent access by unauthorized users.
Computrace agent – For tracking and tracing services, available in select countries, separate software and purchase of a
subscription is required.
Thermal and power management – The HP BIOS provides and enables thermal and power management technologies so
component temperatures are managed for high reliability and to assist in operating the HP Business Desktop computer in any
enterprise environment.
Acoustic performance – Industry leading acoustic emissions across the range of operating conditions.
Serviceability – HP BIOS provides diagnostic and detailed service information.
Upgrades and recovery – HP BIOS provides numerous ways to upgrade HP Business Desktop computers, including BIOS
updates from within DOS (Flashbin), BIOS updates from within Windows (HPQFlash, SSM), HP Client Manager, and fail-safe
recovery. In addition, the HP Business Desktop BIOS Utilities tool enables replicated BIOS setup throughout the Enterprise; it is
available from within the BIOS software and from the support website.
Additional HP BIOS Features
Power-On password – Helps prevent an unauthorized user from powering on the system. After a TPM Basic User password is
established in windows, the user or admin can require TPM hardware based authentication during the power-on process.
Administrator password – Also known as the setup password, this helps prevent unauthorized changes to the system
configuration. If the administrator password is not known, the BIOS version cannot be changed and changes cannot be made
to BIOS settings using F10 setup or under the OS.
Advanced Configuration and Power Interface (ACPI) – Represents a significant innovation in power and configuration
management, allowing operating systems and applications to manage power based on activity and usage. HP Compaq
dc7900 models use ACPI to provide power conservation features.
Other Features
ACPI-Ready Hardware

Description
Advanced Configuration and Power Management Interface (ACPI).

Allows the system to wake from a low power mode.
Controls system power consumption, making it possible to place individual cards and
peripherals in a low-power or powered-off state without affecting other elements of the system.
SMBIOS Ver. 2.5

Drive Lock
Implementation of the industry standard ATA Security feature set. When enabled, it
prevents software access to user data on the drive until one or two user-defined
passwords are provided.
Drive Self Tests (DPS)*
Drive Protection System
A diagnostic hard drive self test. It scans critical physical components and every
sector of the hard drive for physical faults and then reports any faults to the user.
Running independently of the operating system, it can be accessed through a
Windows-based diagnostics utility or through the computer's setup procedure. It
produces an evaluation on whether the hard drive is the source of the problem and
DPS Access through F10 Setup during Boot
needs to be replaced.
The system expands on the Self-Monitoring, Analysis, and Reporting Technology
(SMART), a continuously running systems diagnostic that alerts the user to certain
types of failures.
SMART Technology*
Allows hard drives to monitor their own health and to raise flags if imminent failures were
(Self-Monitoring, Analysis and Reporting
predicted
Technology)
Predicts failures before they occur. Tracks fault prediction and failure indication
SMART I – Drive Failure Prediction
parameters such as re-allocated sector count, spin retry count, calibration retry
count
SMART II – Off-Line Data Collection
By avoiding actual hard drive failures, SMART hard drives act as "insurance"
against unplanned user downtime and potential data loss from hard drive failure
SMART III – Off-Line Read Scanning with
IOEDC: I/O Error Detection Circuitry
Defect Reallocation
Detects errors in Read/Write buffers on HDD cache RAM
Interface in F10 setup for all dc7900 platforms provides confirmation of SMART IV
SMART IV – End-to-End CRC for hard drives
support.
* This feature is inoperable when a RAID (Redundant Array of Independent Disks) configuration is enabled.

Memory

Graphics memory is shared with system memory. Graphics memory usage varies
depending on the amount of system memory installed, BIOS settings, operating
system, and system load. 32 MB is pre-allocated for graphics use at system boot time.
Additional memory can be allocated at boot time by the BIOS for PAVP (Protected
Audio Video Playback) support for playback of protected video content. For Vista, use
of PAVP heavy mode preallocates an additional 96MB.
Additional memory is allocated for graphics as needed using Intel's Dynamic Video
Memory Technology (DVMT), to provide an optimal balance between graphics and
system memory use.
