PCI is a high-speed standard local bus for interfacing a number of I/O
components to a PC processor and memory subsystem. The PCI

Interface Descriptions

1-3

functionality for the LSI21003 is contained within the LSI53C1010-33.
The chip connects directly to the PCI bus and generates timing protocol
in compliance with the PCI specification.
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1 (see Figure 2.1). The signal
definitions and pin numbers conform to the PCI Local Bus Specification
Revision 2.2 standard. The LSI21003 conforms to the PCI universal
signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface
The SCSI functionality for the host adapter is also contained within the
LSI53C1010-33. The chip connects directly to the two SCSI buses for SE
or LVD SCSI applications and generates timing and protocol in
compliance with SCSI standards. One SCSI interface operates at a burst
transfer rate of up to 40 Mbytes/s for wide Ultra SCSI transfers, and the
other up to 160 Mbytes/s for wide Ultra160 SCSI transfers.
Channel A is SE only with active autosensing termination. The
Channel A interface is made through connectors J2, J3, and J4.
Connector J2 is a 68-pin high density right-angle receptacle for internal
SCSI connections. Connector J3 is a 50-pin high density right-angle
receptacle that protrudes through the ISA/EISA bracket. Connector J4 is
a 50-pin narrow (ribbon) internal connector.
Channel B may be either SE or LVD with active termination always
enabled. The Channel B interface is made through connector J5. J5 is a
68-pin high density right-angle connector for internal SCSI connections.
See Figure 2.1 on page 2-5 for the location of these connectors.
The LSI21003 supplies SCSI bus TERMPWR through a blocking diode
and self-resetting 1.5 A short circuit protection device.
A 40 MHz oscillator on the host adapter provides the clock frequency to
the LSI53C1010-33 that is necessary to support SCSI transfers.

1-4

Using the LSI21003

1.3.3 SCSI Activity LED Interface
The SCSI activity LED interface is a four-wire arrangement that allows
connection of an LED harness to the board. The connector on the host
adapter is J6 for both channels. See Table 3.8 on page 3-12 for the signal
name and pin numbers on this interface.

1.3.4 Cabling
The cable provided in the kit is matched for a Fast/Ultra/Ultra2/Ultra160
SE or LVD operation. This cable also has built-in multimode (SE/LVD)
termination since most Ultra160 hard disk drives are not made with
on-board LVD termination.
Table 1.1 lists standard cable specifications.

1. This parameter may be exceeded in point-to-point and engineered
applications.
2. LVD was not defined in the original SCSI standards for this speed. If all
devices on the bus support LVD, then 12-meter operation is possible at
this speed. However, if any device on the bus is SE only, then the entire
bus switches to SE mode, and the distances in the SE column apply.
3. SE and High Voltage Differential (HVD) are not defined at greater than
Ultra speeds.

LSI21003 PCI to Dual Channel SCSI Host Adapter

2-1

A 32-bit slot should be used. The LSI21003 will work in a
64-bit slot, but only 32 bits are used. The host adapter requires
a PCI slot that allows bus master operation. See Figure 2.2 on
page 2-6.
Step 6. Remove the blank bracket panel on the back of the computer
aligned with the PCI slot you intend to use.
Save the bracket screw for securing the installed board.
Step 7. Carefully insert edge connector J1 of the host adapter into the
PCI slot. Make sure the edge connector is properly aligned
before pressing the board into place. See the example in
Figure 2.2.
Note:

You may notice that the components on the PCI Host
Adapter face the opposite way from those on other non-PCI
plug-in boards you have in your system. This is correct, and
the board is keyed to go in only one way.

Step 8. Secure the board with the bracket screw before making the
internal and external SCSI bus connections (see Figure 2.2).
Step 9. If you are connecting any internal SCSI devices, plug the end
of an appropriate internal SCSI ribbon cable into the connector
that provides the performance/features your system needs (see
Figure 2.1 on page 2-5).
Make certain you match pin 1 on both connectors. Chain your
internal devices on this cable.
Step 10. Connect the LED cable to J6 if desired.
This is designed to drive the front panel LED found on most PC
cabinets to indicate activity on the SCSI bus. See Table 3.8 for
the signal name and pin numbers for the LED interface.
Step 11. Make all external SCSI bus connections.
Step 12. Terminate the SCSI bus.
Step 13. Set SCSI IDs as required.
You must not have duplicate SCSI IDs.
Step 14. Replace the cabinet cover.
Step 15. Refer to the PCI Storage Device Management System SDMS
4.0 User’s Guide (or the guide for the software that you will use)
to load the driver software for your particular operating system.

Each SCSI host adapter that you install can act as host for up to
15 peripheral devices (depending on the SCSI bus speed), not including
the adapter itself.

Detailed Installation Procedure

2-3

2.2.2 Inserting the Host Adapter
For safe and proper installation, check the user’s manual supplied with
your computer and perform the following steps:
Step 1. Ground yourself before removing the host adapter board from
its package.
Note:

Static charges on your body can damage electronic
components. Handle plug-in boards by the edge; do not
touch board components or gold connector contacts. The
use of a static ground strap is recommended.

Step 2. Remove the LSI21003 from its packing and verify that it is not
damaged.
An example of this host adapter board is shown in Figure 2.1.
Step 3. Switch off the computer and unplug power cords for all
components in your system.
Step 4. Remove the cover from your computer per the instructions in
the user’s manual for your system to access the PCI slots.
Make sure you are adequately grounded.
Step 5. Locate the slots for PCI plug-in board installation.
A 32-bit slot should be used. The LSI21003 will work in a
64-bit slot, but only 32 bits are used. The host adapter requires
a PCI slot that allows bus master operation. See Figure 2.2.
Step 6. Remove the blank bracket panel on the back of the computer
aligned with the PCI slot you intend to use.
Save the bracket screw.
Step 7. Carefully insert edge connector J1 (see Figure 2.1) of the host
adapter into the PCI slot.
Make sure the edge connector is properly aligned before
pressing the board into place as shown in Figure 2.2. The
bracket around connector J3 should fit where you removed the
blank panel.
Note:

2-4

You may notice that the components on a PCI host adapter
face the opposite way from non-PCI adapter boards you

Installing the LSI21003

have in your system. This orientation is correct. The board
is keyed and can only be inserted one way.
Step 8. Secure the board with the bracket screw (see Figure 2.2) before
making the SCSI bus connections.

2.2.3 Connecting the SCSI Peripherals
All internal SCSI bus connections to the LSI21003 are made with an
unshielded, 68- or 50-conductor ribbon cable (see Figure 2.3). One side
of this cable is marked with a color to indicate the pin-1 side. The
connectors on this cable are keyed to ensure a proper pin-1 connection.
Use Ultra/Ultra2/Ultra160 rated cables for these bus speeds. (See
Table 1.1 in Chapter 1.)

2-6

Installing the LSI21003

For convenience, Channel A also has a 50-pin narrow (ribbon) connector.
Some internal cables come with an SE/LVD terminator on one end. This
end should be furthest from the host adapter.
All external SCSI bus connections to the LSI21003 are made with a
shielded, 50-pin high density cable (see Figure 2.3). The connectors on
this cable are always keyed to ensure a proper pin-1 connection.

Most PC cabinets are designed with a front panel LED. If you wish to
enable this feature, follow Step 4.
Step 4. Connect the LED cable to connector J6 on the host adapter, as
shown in Figure 2.8.
When properly connected, the front panel LED lights when
there is activity on the SCSI bus.
Connector J6 is not keyed. The orientation of the LED cable
should not matter as long as all four pins are connected. If the
LED does not light during SCSI bus activity from this host
adapter, you may have to rotate the LED cable connector 180°
on J6. If your connector has only two wires, refer to Table 3.8
on page 3-12 for connector pinout information.

Step 3. Chain multiple devices together with shielded external SCSI
cables.
An example of these chained connections is shown in
Figure 2.11.
Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 SCSI Bus Termination
The devices making up the SCSI bus are connected serially (chained
together) with SCSI cables. The first and last physical SCSI devices
connected on the ends of the SCSI bus must have their terminators
active. All other SCSI devices on the bus must have their terminators
removed or disabled. Remember that your LSI21003 is also on the SCSI

bus and its termination is automatically enabled when it is connected to
the end of the bus.
Important:

To utilize Ultra160 SCSI performance, you must only have
LVD devices on the bus. Do not mix any SE devices with
LVD devices or the entire bus will drop to SE, limiting bus
performance to Ultra SCSI levels.

LVD peripheral devices are normally terminated with external
terminators, but are sometimes set with jumpers or with a switch on the
peripheral. Refer to the peripheral manufacturer’s instructions and to the
computer’s user’s manual for information on how to identify the
terminator setting of each device and how to change it.
Caution:

The autoenable/disable sensing feature on your LSI21003
may enable termination erroneously if it is directly cabled to
another SCSI device or host adapter using the same
sensing method. The LSI21003 senses SCSI devices by
detecting the ground signal on conductor 22 of a
50-conductor internal cable, conductor 36 of a
50-conductor external cable, or conductor 50 of a
68-conductor cable.

The LSI21003 automatically controls SCSI bus termination for four
different bus configurations. The four bus configurations are:

•

Connections for high density internal SCSI connections

•

Connections to high and low density internal connectors

•

Connections for external SCSI connection

•

Connections to both internal and external SCSI connectors

These terminations are discussed below. Please note that only SE
termination control is allowed on Channel A.
2.2.4.1 High Density Internal SCSI Connections
If only internal SCSI device connections on the host adapter have been
made, then terminate the last internal device on the SCSI bus. You must
disable the termination on all other devices. Termination on the LSI21003
is automatically enabled for Channel A. The termination for Channel B is
enabled all the time.

2.2.4.2 Internal SCSI Connections for Both Internal Connectors
If internal SCSI device connections to both internal connectors (J2 and
J4) on your host adapter have been made, then terminate the internal
devices on each end of the SCSI bus. You must disable the termination
on all other devices. Termination on Channel A of your host adapter is
automatically disabled in this case. Remember, you must not use the
external connector J3 if you use both internal connectors.

2.3 Setting SCSI IDs
Set each SCSI device and the host adapter to a separate SCSI ID,
0 through 15. SCSI ID 7 is the preset host adapter setting, giving it the
highest priority on the bus. If you plan to boot your computer from a hard
disk drive on the SCSI bus, that drive should have SCSI ID 0, or the
lowest SCSI ID on the bus. Chapter 2 “SCSI BIOS” of the PCI Storage
Device Management System SDMS 4.0 User’s Guide explains how to set
your host adapter ID using the SCSI BIOS Configuration Utility.
Note:

Devices on a narrow (8-bit) bus only respond to SCSI IDs
0–7. Also, they will not be able to respond to the host
adapter if the host adapter ID is set higher than 7.

The peripheral device SCSI IDs are usually set with jumpers or with a
switch on the peripheral. Refer to the peripheral manufacturer’s
instructions and to the computer’s users manual to determine the ID of
each device and how to change it. No duplication of SCSI IDs is allowed
on a SCSI bus.
Step 1. Determine the SCSI ID of each device on the SCSI bus, noting
any duplications.
Step 2. Make any necessary changes to the SCSI IDs and record the
IDs for future reference.
Table 2.1 is provided to keep this record.

2.4 Setting Interrupts (Exceptional Cases)
Normally, you do not change the default interrupt routing for the
LSI21003, since performance is usually increased by having two
separate interrupts.
However, if your system does not support two separate interrupts, the
INTA/INTB/ jumper is provided to change the interrupt routing. This
capability requires enabling the INTA/INTB/ to act as a jumper for special
configuration purposes. This feature is not packaged with the standard
LSI21003, as the default interrupt routing is sufficient for most systems.
In the exceptional case, where a user would require jumper settings,
Table 2.2, “Setting Interrupts,” explains these settings:

3.2.2 The SCSI Interface
The SCSI interface conforms to ANSI X3T10.11/1142.
The SCSI interface operates as two 16-bit, SE or LVD channels, and
supports Fast, Ultra, Ultra2, and Ultra160 SCSI protocols. The interface
is made through connectors J2, J3, and J4 for Channel A and J5 for
Channel B.
J2 is a 68-pin high density right-angle connector for internal SCSI
connections to Channel A. J3 is a 50-pin high density right-angle
connector that protrudes through the ISA/EISA bracket for external
connections to Channel A. Also on Channel A is connector J4, which is
a 50-pin narrow (ribbon) connector for internal connections. Channel A
has autosensing, active SE SCSI termination.
J5 is a 68-pin high density latching right-angle connector for internal
SCSI connections to Channel B. Channel B has active, SE or LVD SCSI
termination that is always enabled.
SCSI TERMPWR is supplied by the board.
Tables 3.4, 3.5, 3.6, and 3.7 document the signal assignments for J2, J3,
J4 and J5 respectively.

The simultaneous accessing of data by more than one SCSI device. This
increases the data throughput.

NVRAM

NonVolatile Random Access Memory. Actually an EEPROM
(Electronically Erasable Read Only Memory chip) used to store
configuration information. See EEPROM.

Operating
System

A program that organizes the internal activities of the computer and its
peripheral devices. An operating system performs basic tasks such as
moving data to and from devices, and managing information in memory.
It also provides the user interface.

Parity Checking

A way to verify the accuracy of data transmitted over the SCSI bus. The
parity bit in the transfer is used to make the sum of all the 1 bits either
odd or even (for odd or even parity). If the sum is not correct, the
information may be retransmitted or an error message may appear.

Passive
Termination

The electrical connection required at each end of the SCSI bus,
composed of a set of resistors. It improves the integrity of bus signals.

PCI

Peripheral Component Interconnect. A local bus specification that allows
connection of peripherals directly to computer memory. It bypasses the
slower ISA and EISA buses.

Peripheral
Devices

A piece of hardware (such as a video monitor, disk drive, printer, or
CD-ROM) used with a computer and under the computer’s control. SCSI
peripherals are controlled through a SCSI host adapter.

Pin-1
Orientation

The alignment of pin 1 on a SCSI cable connector and the pin-1 position
on the SCSI connector into which it is inserted. External SCSI cables are
always keyed to insure proper alignment, but internal SCSI ribbon cables
sometimes are not keyed.

PIO

Programmed Input/Output. A way the CPU can transfer data to and from
memory using the computer’s I/O ports. PIO is usually faster than DMA,
but requires CPU time.

Port Address

Also Port Number. The address through which commands are sent to a
host adapter board. This address is assigned by the PCI bus.

Port Number

See Port Address.

Queue Tags

A way to keep track of multiple commands that allow for increased
throughput on the SCSI bus.

RAM

Random Access Memory. The computer’s primary working memory in
which program instructions and data are stored and are accessible to the
CPU. Information can be written to and read from RAM. The contents of
RAM are lost when the computer is turned off.

RISC Core

LSI Logic SCSI chips contain a RISC (Reduced Instruction Set
Computer) processor, programmed through microcode SCRIPTS.

ROM

Read Only Memory. Memory from which information can be read but not
changed. The contents of ROM are not erased when the computer is
turned off.

SCAM

SCSI Configured AutoMatically. A method to automatically allocate SCSI
IDs using software when SCAM compliant SCSI devices are attached.

SCSI

Small Computer System Interface. A specification for a high-performance
peripheral bus and command set. The original standard is referred to as
SCSI-1.

SCSI-2

The SCSI specification which adds features to the original SCSI
standard.

SCSI-3

The current SCSI specification which adds features to the SCSI-2
standard.

SCSI Bus

A host adapter and one or more SCSI peripherals connected by cables
in a linear chain configuration. The host adapter may exist anywhere on
the chain, allowing connection of both internal and external SCSI
devices. A system may have more than one SCSI bus by using multiple
host adapters.

SCSI Device

Any device that conforms to the SCSI standard and is attached to the
SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI
peripherals.

SCSI ID

A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI
bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15
for Wide SCSI). The host adapter usually gets the highest ID, (7 or 15)
giving it priority to control the bus.

SCSI SCRIPTS

A SCSI programming language that works with the SCRIPTS processor
that is embedded on the LSI53C1010-33 device. These SCRIPTS reside
in the host computer system memory.

SCRIPTS
Processor

The SCRIPTS processor allows users to fine tune SCSI operations with
regard to unique vendor commands or new SCSI specifications. The
SCRIPTS processor fetches SCRIPTS instructions from system memory
to control operation of the LSI53C8XX device.

SDMS

Storage Device Management System. An LSI Logic software product that
manages SCSI system I/O.

Single-Ended
(SE) SCSI

A hardware specification for connecting SCSI devices. It references each
SCSI signal to a common ground. This is the most common method (as
opposed to differential SCSI which uses a separate ground for each
signal).

STA

SCSI Trade Association. A group of companies that cooperate to
promote SCSI parallel interface technology as a viable mainstream I/O
interconnect for commercial computing.

Synchronous
Data Transfer

One of the ways data is transferred over the SCSI bus. Transfers are
clocked with fixed frequency pulses. This is faster than asynchronous
data transfer. Synchronous data transfers are negotiated between the
SCSI host adapter and each SCSI device.

System BIOS

Controls the low-level POST (power-on self-test), and basic operation of
the CPU and computer system.

Ultra SCSI

A standard for SCSI data transfers. It allows a transfer rate of up to
20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit
SCSI bus. SCSI Trade Association (STA) supports using the term “Ultra
SCSI” over the older term “Fast-20”.

Ultra2 SCSI

A standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus. SCSI Trade Association (STA) supports using the term
“Ultra2 SCSI” over the term “Fast-40”.

Ultra160 SCSI

A standard for SCSI data transfers. It allows a transfer rate of up to
160 Mbytes/s over a 16-bit SCSI bus.

VCCI

Voluntary Control Council for Interference.

VDE

Verband Deucher Elektroniker (Association of German Electrical
Engineers).

Virtual Memory

Space on a hard disk that can be used as if it were RAM.

Wide SCSI

A SCSI-2 feature allowing 16-bit or 32-bit transfers on the SCSI bus. This
dramatically increases the transfer rate over the standard 8-bit SCSI bus.

Wide Ultra SCSI

The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 40 Mbytes/s.

Wide Ultra2
SCSI

The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 80 Mbytes/s.

Wide Ultra160
SCSI

The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 160 Mbytes/s.

Word

A two byte (or 16-bit) unit of information.
