Host Adapter Scsi Id Selections - Acer Altos 900 Pro User Manual

HOST ADAPTER SCSI ID
This parameter allows you to change the host controller SCSI ID.
Figure 3-3 shows the available IDS for use with the AIC-7880. The
default setting is SCSI ID 7, which has the highest priority on the
SCSI bus. We recommend that you keep the default setting since
most system applications run only in this setting.

the device's priority on the bus during the arbitration phase. The
arbitration phase determines which device controls the bus when two
or more devices request for the use of it.
Use the or keys then press to select the SCSI ID if you
