AAA-130U2 Series Installation and Hardware Guide
■
Enable Disconnection —When set to Yes, allows the SCSI
device to disconnect from the SCSI bus (sometimes called
Disconnect/Reconnect). Leave the setting at Yes if two or more
SCSI devices are connected to the AAA-131U2/133U2. If only
one SCSI device is connected, changing the setting to No
results in slightly better performance.
■
Initiate Wide Negotiation —When set to Yes, the AAA-131U2/
133U2 attempts 16-bit data transfer (wide negotiation). When
set to No, the AAA-131U2/133U2 uses 8-bit data transfer
unless the SCSI device requests wide negotiation. For Ultra2
SCSI devices, make sure this option is set to Yes.
Note:
Set Initiate Wide Negotiation to No if you have
an 8-bit SCSI device that hangs or exhibits other
performance problems.
■
Send Start Unit Command —When set to Yes, sends the Start
Unit Command to the SCSI device at bootup.
■
Include in BIOS Scan —When set to Yes, the AAA-131U2/
133U2 BIOS includes the device as part of its BIOS scan at
bootup. Leave this setting at Yes for all hard disks that are part
of an array.
Additional Options
■
Array1000U2 BIOS —When set to Enabled, the AAA-131U2/
133U2 BIOS is installed and all Int13 (except bootable
CD-ROM) devices are supported at boot time. When set to
Disabled, the AAA-131U2/133U2 BIOS is not installed.
■
BIOS Support for Bootable CD-ROM —When set to Enabled,
the AAA-131U2/133U2 BIOS allows booting from a CD-ROM
drive.
