Adapter Setup - Asus PCI-SIU2 User Manual

4. Host Adapter Setup
Spin Up Disk Drive. This option is used to initiate motor spin-up for SCSI
disk drives. The host adapter BIOS can limit system power requirements dur-
ing power-up. This is accomplished by signaling the device to start at delayed
intervals (default setting will be 'No').
Enable Disconnect. The host adapter uses this option to allow a device to
temporarily disconnect from the SCSI bus (referred to as disconnect/recon-
nect). This allows the host adapter to perform other functions on the bus while
the device is temporarily disconnected. The device and the host adapter can
then reconnect when the bus is needed (default setting will be 'Yes').
Enable Wide Negotiation. This option determines whether the host adapter
initiates wide data transfer with the specified SCSI device. However, not all
SCSI devices can handle wide data transfer negotiations properly, which may
cause system failure. Certain old CD-ROM, CD-Recordable, and tape drives
cannot handle a Wide Transfer negotiation request from the PCI-SIU2 and
may fail to start the system. In such cases, use SmartSCSI to disable (NO
check) the Wide Negotiation setting for the SCSI ID of the anomalous device.

Adapter Setup

Host Adapter SCSI Bus ID. Used to change the adapter's SCSI ID on the
SCSI bus. The narrow host adapters provides eight ID's available numbered 0-
7, with 7 having the highest priority (and ID-7 reserved for the host adapter).
Installation of multiple host adapters is permitted on the same SCSI bus. This
option allows the system to have more than one SCSI bus attached. Under
these conditions, SCSI ID's must be mutually exclusive.
SCSI Terminators. This option is used to set host adapter termination located
on the host adapter card. This option is also used to manually control termina-
tion on the host adapter. The normal setting for this option is auto.
SCSI Parity Check ON. Select this option to enable or disable parity check-
ing on the SCSI bus by the host adapter. The default setting for this option is
ON (Yes).
