Who This Manual Is For
This manual is for anyone who wants to:
•Add a SCSI accessory to their PC.
•Configure a SCSI accessory in an HP PC.
Important Safety Information
WARNING If you have any doubt that you can lift the PC or display safely, do not
try to move it without help.
For your safety, always connect the equipment to a grounded wall
outlet. Always use a power cord with a properly grounded plug, such
as the one provided with this equipment, or one in compliance with
your national regulations. This PC is disconnected from the power by
removing the power cord from the power outlet. This means the PC
must be located close to a power outlet that is easily accessible.
For your safety, never remove the PC’s cover without first removing
the power cord from the power outlet, and any connection to a
telecommunications network. Always replace the cover on the PC
before switching it on again.
To avoid electric shock, do not open the power supply. There are no
user-serviceable parts inside.
This HP PC is a class 1 laser product. Do not attempt to make any
adjustment to the laser units.

Configuring the SCSI Bus
Configuring the SCSI Bus
You can configure your PC’s SCSI bus using the SCSISelect utility. This
utility is for use with Internal Wide 16-bit SCSI devices.
Using SCSI Select
ATTENTION The SCSISelect™utility is intended for advanced users only.
Note that the SCSISelect option displayed on your screen may
be different to the one described here.
The SCSISelect utility is accessed by pressing <Ctrl><A> during the

InterfaceSettingsMenu It is recommended that you do not change these settings.
SCSI Channel Interface Definitions:
•Host Adapter SCSI ID
Changes the adapter SCSI ID from its default value of 7.
•SCSI Parity Checking
Enable or disable host adapter SCSI parity checking. Most currently
available SCSI devices do support SCSI parity. You should disable
SCSI Parity Checking if any of the attached SCSI devices do not
support SCSI parity.
•Host Adapter SCSI Termination
It is recommended that you leave this field on its default setting of
Automatic. This way, if the host adapter detects a SCSI device
connected to either its internal or external connectors, then it
enables its terminators (the adapter is at the end of the SCSI bus). If
the host adapter detects devices connected to both its internal and
external connectors, then it disables its terminators.

•Initiate Sync Negotiation
Some older SCSI-1 devices do not support synchronous negotiation.
Set Initiate Sync Negotiation to No for these devices.
•Maximum Sync Transfer Rate
If the SCSI device is an UltraWide SCSI device, you can use the
maximum value of 40.0 MB per second. For Ultra narrow SCSI or
Wide SCSI devices you can select a maximum transfer rate of 20.0
MB per second.
Certain older SCSI-1 devices do not support UltraWide SCSI (up to
40 MB per second) or Ultra narrow SCSI or Wide SCSI data transfer
rates (up to 20 MB per second). Select a Maximum Sync Transfer
Rate of 10.0 MB per second for these devices.

Configuring the SCSI Bus
It is strongly recommended that you switch the Maximum Sync
Transfer Rate to 20 MB per second when connecting an external
SCSI device.
•Enable Disconnection
To optimize SCSI bus performance, Enable Disconnection should be
set to Yes.
•Initiate Wide Negotiation
This option determines whether the SCSI channel attempts 16-bit
data transfer instead of 8-bit data transfer.
•Send Start Unit Command
When set to Yes this option reduces the load on your computer’s
power supply by allowing the interface to power-up SCSI devices
one-at-a-time when you start your computer.
This option is not supported by some SCSI devices. Some SCSI
devices require a jumper to be changed before they can respond to
this command.
•BIOS Multiple LUN Support
More advanced SCSI devices can have several logical units (LUN).
This option determines whether booting a SCSI device that has
multipleLUNsissupported.SetthisoptiontoYes ifyourbootdevice
has multiple LUNs. It is set to no by default.
•Include in BIOS Scan
Thissetting,when settoYes,allowstheSCSIdevicetobe controlled
by the host adapter with this SCSI ID. When set to No, the adapter
does not control the SCSI device.

Options Menu It is recommended that these settings are not changed.
Use the and keys to move between options. Press to
display a menu with a selection of values.
•Plug and Play Scam Support
When enabled, this option automatically configures Plug and Play
compatible SCSI devices. For SCSI devices that do not support Plug
and Play, set this option to Disabled. By default, it is enabled.
•Extended BIOS Translation for DOS Drives >1 GByte
This option is no longer used (and must always be “Enabled”).
•Reset SCSI Bus at IC Initialization
When the SCSI controller receives an IC Reset command from the
central processor, it can reset either itself and the SCSI bus, or just
itself. By default, it will reset both itself and the SCSI bus.
•Host Adapter BIOS
This option enables or disables the SCSI Adapter BIOS. Several
options in SCSISelect utility are only valid if the SCSI adapter BIOS
is enabled. The SCSI adapter BIOS must be enabled if the computer
boots from a SCSI hard disk drive. This option is enabled by default.
•Support Removable Disks Under BIOS as Fixed Disks
When Boot Only is selected, only the removable media drive
designated as the boot device is treated as a hard disk drive.
If All Disks is selected, all removable-media drives supported by
theBIOS are treatedas hard diskdrives. No removable-mediadrives
are treated as hard disk drives when Disabled is selected. In this
case, removable-media drives must be controlled through operating
system drivers.

•Display <Ctrl><A> Message During BIOS Initialization
When enabled, this option displays the message Press <Ctrl><A>
for SCSISelect(TM) Utility! during BIOS initialization. When
disabled, this message is not displayed, although you can still press
the <Ctrl><A> key combination for the SCSISelect utility. This
option is enabled by default.
•BIOS Support for Bootable CD-ROM
When enabled, this option provides BIOS support to boot your PC
from a CD-ROM device connected to the SCSI host adapter.
•BIOS Support for Int13 Extensions
When enabled, this option provides BIOS support for hard disk
drives with more than 1024 cylinders. It is enabled by default.
SCSI Disk Utilities WhentheSCSI Disk Utilities are selectedfrom the initial Options menu,
the SCSISelect utility scans the SCSI bus and lists all the SCSI devices
on the SCSI bus. The list shows the SCSI ID and name of each SCSI
device. You can use this list to discover the SCSI ID of any device on the
SCSI bus.
Use the and keys to highlight a device and press to
display the Format Disk/Verify Media menu.
•Format Disk
This utility can be used to perform a low-level format of a hard disk.
Most SCSI disks are pre-formatted and do not need low-level
formatting.Youshouldnotethatthisfunctioncantakeseveralhours.
•Verify Disk Media
This utility scans for media defects on the selected SCSI device.
