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

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

computer’sstart-upprocesswhenthe messagePress <Ctrl><A> for

The Options menu is displayed.

Use the and keys and the key to make selections in

the SCSISelect utility. Press at any time to return to the previous

menu.

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.
