2English
There are two ways to configure a SCSI accessory:
•SCSISelect — for use with Internal Wide 16-bit SCSI devices
& HP FastRAID (Adaptec).
•SCSI Configuration Utility — for use with External and Internal
16/8-bit SCSI devices (Symbios).
NOTE You cannot boot from a device connected to the Symbios controller
when HP FastRAID is installed.
To disable a boot device:
1Go to the Advanced menu in the Setup program.
2Select the SCSI channel you wish to set.
3Enable or disable the Option ROM Scan as required.
Using SCSI Select
ATTENTION The SCSISelect™utility is intended for advanced users only.
Note that the SCSISelect options displayed on your screen may
be different from those described here. Some options are not
displayed if the HP FastRAID option is installed.
The SCSISelect utility is accessed by pressing during the
computer’s start-up process when the message Press for
SCSISelect(TM) Utility! is displayed.

•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.
•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. When set to No each
SCSI device powers up at the same time.
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
multiple LUNs is supported. Set this option to Yes if your boot device
has multiple LUNs. It is set to no by default.
•Include in BIOS Scan
This setting, when set to Yes, allows the SCSI device to be controlled
by the host adapter with this SCSI ID. When set to No, the adapter
does not control the SCSI device.

Parity Symbios Logic PCI to SCSI host adapters always generate parity, but
some SCSI devices do not. For this reason you can disable parity
checking.
NOTE When disabling parity checking, you may have to disable disconnects for
certain devices as parity checking for the re-selection phase is not
disabled. If a device does not generate parity, and it disconnects, the I/O
never completes because the re-selection never completes.

Host SCSI ID In general it is not advisable to change your host adapter ID from the
default value of 7, as this gives it the highest priority on the SCSI bus.
However, if you have two adapters sharing the same SCSI devices, you
should give one of the adapters a currently-unassigned ID to avoid
duplication of SCSI IDs.
Scan Order This option lets you tell the host adapter BIOS and your 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 you have more than one device on a SCSI
bus, changing the device order changes the drive letters which are
assigned to them by the system. This will change the boot order.
Removable Media
Support
Only used when removable disk drives are installed. For more
information, refer to the User’s Guide that came with you removable
disk drive.
CHS Mapping When performing a ‘low format’, CHS mapping should be set to
Alternate CHS Mapping for full compatibility with other SCSI
adapters. This is the default setting.
