·
Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI host bus
adapter attempts 16-bit data transfer (wide negotiation). When set to No, the
SCSI host bus adapter uses 8-bit data transfer unless the SCSI device requests
wide negotiation.
NOTE
·
Enable Disconnection—(Default: Yes) When set to Yes, allows the SCSI
device to disconnect from the SCSI bus. Leave the setting at Yes if two or more
SCSI devices are connected to the SCSI host bus adapter. If only one SCSI
device is connected, changing the setting to No results in slightly better
performance.
·
Send Start Unit Command—(Default: Yes) When set to Yes, the Start Unit
Command is sent to the SCSI device at bootup.
The following three options have no effect when the SCSI host bus adapter BIOS is
disabled. (The SCSI host bus adapter BIOS is normally enabled by default.)
·
Enable Write Back Cache—(Default: N/C) Can be used to enable or disable
the write-back cache on SCSI disk drives connected to the host adapter. Leave
this option at its default setting of N/C (no change), which usually allows for
optimum drive performance.
·
BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the
device does not have multiple Logical Unit Numbers (LUNs). When set to Yes,
the SCSI host bus adapter BIOS provides boot support for a SCSI device with
multiple LUNs (for example, a CD "juke box" device in which multiple CDs can
be accessed simultaneously).
·
Include in BIOS Scan—(Default: Yes) When set to Yes, the SCSI host bus
adapter BIOS includes the device as part of its BIOS scan at bootup.
Set Initiate Wide Negotiation to No if you are using an 8-bit
SCSI device that hangs or exhibits other performance
problems with 16-bit data transfer rate enabled.
