1.1 General Description
The LSI Logic LSIU40HVD provides a SCSI-3, Ultra SCSI interface to
PCI computer systems. Installing this adapter in your PCI system allows
connection of SCSI devices over a SCSI bus.
The dual channel LSIU40HVD provides a 16-bit differential, SCSI
solution for your computer, using only one PCI slot. This board can
support both legacy Fast SCSI devices and the newest Ultra SCSI
devices. It is also backwards compatible with the existing LSI8751D host
adapter.
The Storage Device Management System (SDMS™) software operates

1.3 Interface Descriptions
This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, and Ultra SCSI.
1.3.1 The PCI Interface
PCI is a high-speed standard local bus for interfacing a number of I/O
components to the processor and memory subsystems in a high-end PC.
The PCI functionality for the LSIU40HVD is contained within the
LSI53C876 PCI to SCSI I/O Processor chip. The LSI53C876 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 the edge connector J1 (see Figure 2.1). The signal
definitions and pin numbers conform to the PCI Local Bus Specification
Revision 2.1 standard. The LSIU40HVD 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 LSIU40HVD is contained within the LSI
Logic LSI53C876. The LSI53C876 chip connects directly to the two SCSI
buses and generates timing and protocol in compliance with the SCSI
standard.
The SCSI interface on the LSIU40HVD operates as a 16-bit,
synchronous or asynchronous, differential bus, and supports Ultra SCSI
protocols and 16-bit arbitration. Each interface is made through the
connectors J2 and J3 (for Channel A), or J5 and J6 (for Channel B).
Connectors J2 and J5 are 68-pin high-density, right-angle receptacles.
Interface Descriptions
1-3
Connectors J3 and J6 are shielded 68-pin VHDCI right-angle receptacles
that protrude through the back panel bracket. See Figure 2.1 for the
location of these connectors.
Differential SCSI active termination is provided on the LSIU40HVD.
Termination is automatically enabled when only one of the connectors J2
and J3 (or J5 and J6) is used, or when an 8-bit device is connected to
the 16-bit J3 or J6 connectors. The LSIU40HVD supplies SCSI bus
TERMPWR (termination power) through a blocking diode and a
self-resetting 1.5 A short circuit protection device. An on-board LED
lights when TERMPWR is off. Separate jumpers for each channel allow
user override of termination.
A 40 MHz oscillator is installed on the LSIU40HVD to provide the clock
frequency to the LSI53C876 chip that is necessary to support Wide Ultra
SCSI transfers of up to 40 Mbytes/s.
1.3.3 Ultra SCSI
The LSIU40HVD has full support for Ultra SCSI as well as supporting
Fast SCSI simultaneously. Ultra SCSI is an extension of the SCSI-3
family of standards that expands the bandwidth of the SCSI bus, allowing
faster synchronous data transfers. Special SCSI cables are specified for
operation with Ultra SCSI devices, and you must consider the total
number of devices and the length of your SCSI bus when setting up your
system. See the section on connecting your SCSI peripherals in
Chapter 2, "Installing the LSIU40HVD," for a more detailed explanation
of SCSI bus connections.

2.2.3.1
Making Internal SCSI Bus Connections
This section provides step-by-step instructions about making internal
SCSI bus connections:
Step 1. If you are connecting an internal SCSI device, plug the 68-pin
connector on one end of a wide internal SCSI ribbon cable into
the connector J2, or J5 (see Figure 2.4).
2-8
Installing the LSIU40HVD
Step 2. Plug the 68-pin connector on the other end of the internal SCSI
ribbon cable into the SCSI connector on your internal SCSI
device. An example of this connection is shown in Figure 2.5.
You must match pin 1 on all connections.
Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device
Connection
2-10
Installing the LSIU40HVD
Step 3. Additional internal SCSI devices are plugged in by using an
internal SCSI ribbon cable with the required number of
connectors attached along its length as shown in Figure 2.6.
An example of this type of chained connection is shown in
Figure 2.7. Make sure to match pin 1 on all connections.

may already be connected to an existing IDE drive. You may
connect this LED cable to your SCSI host adapter, as shown in
Figure 2.8. This connection causes the front panel LED to
indicate activity on the SCSI bus.
The LED connectors J4 and J7 (see Figure 2.1) are not keyed.
The orientation of the LED cable does not matter as long as all
four pins are connected.
Figure 2.8 SCSI LED Connectors
J7
J4
Some LED cables have only two wires. In this case, place the
connector on one end or the other of J4 or J7. If the LED does not
light during SCSI bus activity from this host adapter, you may have
to rotate the LED cable 180° on J4 or J7.
See Table A.5 in Appendix A for connector pinout information.
Detailed Installation Procedure
2-13
2.2.3.2
Making External SCSI Bus Connections
SCSI bus connections:
68-pin VHDCI connector on one end of a shielded external high
density cable (see Figure 2.3) into the host adapter connector
J3 or J6 (see Figure 2.1).
This connector is now bracketed to the back panel of your
computer. Figure 2.9 shows how this connection is made.
Figure 2.9 External Cable to Host Adapter
2-14
Installing the LSIU40HVD
Step 3. To connect more than one external SCSI device to the host
adapter, you must chain them 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 a set of resistors
called terminators. All other SCSI devices on the bus must have their
terminators removed or disabled.
2-16
Installing the LSIU40HVD
Remember: The LSIU40HVD is also on the SCSI bus; its termination is
automatically enabled when it is connected to the end of
the bus.
Differential 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
user’s manual for your computer for information on how to identify the
terminator setting of each device and how to change it.
Caution:
The auto-enable/disable sensing feature on the
LSIU40HVD may enable termination erroneously if it is
directly cabled to another SCSI device or host adapter
using the same sensing method. The LSIU40HVD senses
SCSI devices by detecting the ground signal on conductor
connect 8-bit devices externally with a 50-conductor SCSI
cable, the ground signal is detected on conductor 34.
The LSIU40HVD automatically covers SCSI bus termination for three
different bus configurations, depending on your use of the connectors on
the LSIU40HVD (see Figure 2.1). The three bus configurations are:
•
•
•
only for internal SCSI connections
only for external SCSI connections
for both internal and external SCSI connections
Termination on the LSIU40HVD for these three different bus
configurations is discussed below.
2.2.4.1
Internal SCSI Connections
If internal SCSI device connections to the host adapter have been made,
you must terminate the last internal device on the SCSI bus. You must
disable the termination on all other devices. Termination on the host
adapter is automatically enabled in this case.
Figure 2.12 shows an example of how termination is determined for this
SCSI bus configuration.
Detailed Installation Procedure
2-17
Figure 2.12 Internal SCSI Device Termination
2.2.4.2
External SCSI Connections
If external SCSI device connections to the host adapter have been made,
you must terminate the last external device on the SCSI bus. You must
disable the termination on all other devices. Termination on the host
adapter is automatically enabled in this case.
Figure 2.13 shows an example of how termination is determined for this
SCSI bus configuration on the LSIU40HVD Channel B.

2.2.4.3
Internal and External SCSI Connections
If internal and external SCSI device connections to the host adapter have
been made, you must terminate the last internal and external devices on
the SCSI bus. You must disable the termination on all other devices.
Termination on the host adapter is automatically disabled in this case.
Figure 2.14 shows an example of how termination is determined for this
SCSI bus configuration on the LSIU40HVD Channel B.
Detailed Installation Procedure
2-19
2.2.4.4
Internal SCSI Connections for both Internal Connectors
If internal SCSI device connection to another LSIU40HVD has been
made, or any connection to a device that uses the same sensing method
for automatic termination as your LSIU40HVD, you must properly set the
termination override jumpers TP2, TP3, TP5, or TP6 (see Figure A.1).
When connecting another LSIU40HVD, or other device that uses the
same termination sensing scheme, you must connect the jumper to both
pins on the TP for the connector used. For example, if another
LSIU40HVD is attached to J3, place the jumper on both stake pins of
TP3.
2.2.5 Setting SCSI IDs
You must 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 SCSI bus. If you plan to boot your computer
from a SCSI hard disk drive on the SCSI bus, that drive should have
SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, “Configuring the
LSIU40HVD,” explains how to set your host adapter ID using the
LSI Logic SCSI BIOS Configuration Utility.
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 user’s manual for your computer to determine the
ID of each device and how to change it. You must have no duplication of
SCSI IDs on a SCSI bus.
Step 1. Determine the SCSI ID of each device on the SCSI bus. Note
any duplications.
Step 2. Make any necessary changes to the SCSI IDs and record the
IDs for future reference. Table 2.2 is provided as a place to
keep this record.

2.3 Setting Interrupts
Normally, you do not change the default interrupt routing for the
LSIU40HVD, since performance is usually increased by having two
separate interrupts. However, if your system does not support two

3.2 Starting the SCSI BIOS Configuration Utility
If you have SCSI BIOS version 4.0 and later, and it includes the
LSI Logic SCSI BIOS Configuration Utility, the default configuration of the
SCSI host adapter(s) can be changed. If a conflict does exist between
device settings or if optimizing system performance is necessary, then
use this Configuration Utility.
The version number of the SCSI BIOS appears in a banner displayed on
your computer monitor during boot. If the Configuration Utility is
available, the following message also appears on your monitor:
Press Ctrl-C to start LSI Logic Configuration Utility...
This message remains on your screen for about five seconds, giving you
time to start the utility. If you decide to press Control C the message
changes to:
Please wait, invoking LSI Logic Configuration Utility...
After a brief pause, your computer monitor displays the Main Menu of the
LSI Logic SCSI BIOS Configuration Utility.
NVRAM is available on this LSI Logic LSIU40HVD. Changes can be
made and stored to NVRAM using this menu driven utility.
3-2
Configuring the LSIU40HVD
Important: This SCSI BIOS Configuration Utility is a powerful tool. If,
while using it, you somehow disable all of your controllers,
pressing Control A(or Control Eon version 4.04 or later)
after memory initialization during reboot allows you to
re-enable and reconfigure.
Not all devices detected by the Configuration Utility can be
controlled by the BIOS. Devices such as tape drives and
scanners require that a device driver specific to that
peripheral be loaded. The device manufacturer provides the
device drivers.
3.2.1 Configuration Utility Main Menu
When you start the LSI Logic SCSI BIOS Configuration Utility, the Main
Menu appears. This menu displays a list of up to four LSI Logic PCI to
SCSI host adapters in your system and information about each of them.
The LSIU40HVD appears on the menu as two LSI53C875 entries; one
for each channel. To select an adapter, use only the arrow keys and the
adapter and the SCSI devices attached to it.
You can select an adapter only if Current Status is on. Changes are
possible only if NVRAM is present on your adapter.

Exit this menu
The settings in this menu are global settings that affect the selected host
adapter and all SCSI devices attached to it. One of these choices can
be selected by highlighting it and pressing Enter.
SCAM Support – The LSI Logic BIOS version 4.0 and above supports
the SCSI Plug and Play protocol called SCAM (SCSI Configured
AutoMatically). SCAM support by default is off in versions 4.09 and later
for the LSI53C876 device. The user may choose to turn this on only if
the system drivers do not require SCAM off. Note that if this BIOS is
flashed onto a board with existing settings, then these settings will not
be changed to reflect the new BIOS defaults. Go into the Configuration
Utility to change these settings.
Parity – The LSI Logic PCI to SCSI host adapters always generate
parity, but some older SCSI devices do not. Therefore, you are offered
the option of disabling parity checking.
3-8
Configuring the LSIU40HVD
Note:
When disabling parity checking, it is also necessary to
disable disconnects for all devices, as parity checking for
the reselection phase is not disabled. If a device does not
generate parity, and it disconnects, the I/O never completes
because the reselection never completes.
Host SCSI ID – This option refers to the host adapter’s SCSI ID, which
is a unique number used to identify the device on the SCSI bus.
Note:
In general, the user should not change the host adapter ID
from the default value of 7, as this gives it the highest
priority on the SCSI bus. Please also note that if you have
8-bit SCSI devices (narrow), they cannot see host IDs
greater than 7.
Scan Order – This option allows the user to tell the SCSI BIOS and
device drivers to scan the SCSI bus from low to high (0 to max) SCSI
ID, or from high to low (max to 0) SCSI ID. If there is more than one
device on the SCSI bus, changing the scan order changes the order in
which drive letters are assigned by the system. Drive order may be
reassigned differently in systems supporting the BIOS Boot Specification
(BBS).
See Chapter 2, “SCSI BIOS,” in the PCI Storage Device Management
System SDMS 4.0 User’s Guide for additional information regarding
BBS.
Note:
This scan order option may conflict with operating systems
that automatically assign a drive order.
Removable Media Support – This option defines the removable media
support for a specific drive. When this option is selected, a window
appears with three choices:
•
•
•
None
Boot Drive Only
With Media Installed
None indicates there is no removable media support whether the drive
is selected in BBS as being first, or first in scan order in non-BBS.
Boot Drive Only provides removable media support for a removable
hard drive if it is first in the scan order.
Starting the SCSI BIOS Configuration Utility
3-9
With Media Installed provides removable media support wherever the
drive(s) actually resides.
One of these choices can be selected by highlighting it and pressing
Enter.
CHS Mapping – This option defines the cylinder head sector (CHS)
values that will be mapped onto a disk without pre-existing partition
information. SCSI Plug and Play Mapping is the default value.
To support interchange with noncompatible systems, there is another
option that can be selected by choosing CHS Mapping and then
cursoring to Alternate CHS Mapping.
Note:
Neither of these options will have any effect after the disk
has been partitioned with the FDISK command.
To remove partitioning, two options are available:
•
•
Reformat the disk using the Format Device option. See Section
3.2.2.2, “Device Selections Menu.”
Use the FDISK /MBR command at the C:\ prompt, where MBR
represents master boot record.
Important: Reformatting the disk or using FDISK /MBR erases all
partitioning and data that exists. Be careful that you target
the correct disk when using either the Format utility or the
FDISK /MBR command.
Note:
After clearing the partitions and data, it is necessary to
reboot and clear memory or the old partitioning data will be
reused, thus nullifying the previous operation.
Spinup Delay (seconds) – This option allows the user to stagger
spinups for a longer period of time to balance the total current load. The
default value is 2 seconds with choices between 1 and 10 seconds.
This is a power management device designed to accommodate disk
devices that may have heavy current load during power-up. If multiple
drives are being powered up simultaneously and drawing heavy current
loads, then this option staggers the spinups to limit start-up current.

Please review the descriptions of each option below before changing any
values.
Sync Rate (MBytes/sec) – This option defines the maximum data
transfer rate the host adapter will attempt to negotiate. The host adapter
and a SCSI device must agree to a rate they can both handle.
Width (bits) – This option defines the maximum SCSI data width the
host adapter will attempt to negotiate. The host adapter and a SCSI
device must agree to a width they can both handle. Only chips that can
do 16-bit data transfers have this option enabled.
Disconnect – SCSI devices have the ability to disconnect from the
initiator during an I/O transfer. This disconnect option frees the SCSI Bus
to allow other I/O processes. Additionally, it tells the host adapter whether
or not to allow a device to disconnect. Some devices run faster with
disconnects enabled (mostly newer devices), while some run faster with
disconnects disabled (mostly older devices).
3-12
Configuring the LSIU40HVD
Read Write I/O Time-out (seconds) – This option sets the amount of
time the host adapter waits for a read, write, or seek command to
complete before trying the I/O transfer again. Because this provides a
safeguard by allowing the system to recover if an I/O operation fails, you
should always set the time-out to a value greater than zero.
Note:
A zero value allows unlimited time for an operation to
complete and could result in the system being hung-up.
Scan for Device at Boot Time – Set this option to no if there is a
device that you do not want to be available to the system. Also, on a bus
with only a few devices attached, you can speed up boot time by
changing this setting to no for all unused SCSI IDs.
Scan for SCSI Logical Units (LUNs) – Set this option to noif problems
arise with a device that responds to all LUNs whether they are occupied
or not. For example, if a SCSI device with multiple LUNs is present on
the system but you do not want all of those LUNs to be available to the
system, then set this option to no. This will limit the scan to LUN 0 only.
Queue Tags – If the device driver has the capability, this option allows
the user to enable or disable the issuing of queue tags during I/O
requests.
Initial Boot – This option allows any device attached to the first adapter
to become the boot device. It provides the users of non-BBS personal
computers with some of the flexibility of a BBS machine.
Format Device – If enabled, this option allows the user to low-level
format a magnetic disk drive. Low-level formatting will completely and
irreversibly erase all data on the drive. Formatting will default the drive to
a 512-byte sector size even if the drive had previously been formatted to
another sector size.
Verify – This option allows the user to read all the sectors on a disk
looking for errors. When selected, this option displays the following
message:
“Verify all sectors on the device
Press ESC to abort
Else press any key to continue”

will be lost upon saving after restoring default setup.
Exit this menu – This option allows the user to leave the Device
Selections Menu and return to the previous screen.
3.3 Exiting the SCSI BIOS Configuration Utility
Because some changes only take effect after the system reboots, it is
important that the user exit from this Configuration Utility properly. Return

A.2.3 The LED Interface
The LED interface on the LSIU40HVD is a four-wire arrangement that
allows the user to connect an LED harness to the board. The
GPIO0_FETCH line (maximum output low voltage 0.4 V and minimum
output low current 16 mA) is pulled low to complete the circuit when a
harness with an LED is attached. The connectors on the LSIU40HVD are
J4 for Channel A, and J7 for Channel B.
