Device Setup Menu
When you select a specific device from the Device Selection menu, your computer
displays the following Device Setup menu. The settings in this menu effect
individual SCSI devices attached to the selected host adapter. Changes made from
this menu will require a system reboot upon exit from the SCSI Configuration
utility.

Sync Rate (Mega Bytes/sec)
- Defines the maximum transfer rate the host adapter
attempts to negotiate. The host adapter and a SCSI device must agree to a rate they
can both handle.
Width (bits)
- Sets the maximum data width the host adapter will attempt to
negotiate. The host adapter and a SCSI device must agree to a width they can both
handle. Only those host adapters that support 16 bit data transfers will show this
option as enabled.
Disconnect
- SCSI devices have the ability to disconnect from the bus during an
I/O transfer. This option tells the host adapter whether or not to allow a device to
disconnect. Some devices run faster with disconnect enabled (mostly newer
devices), while some run faster with disconnect disabled (mostly older devices).
Read Write I/O Timeout (secs)
- This option sets the time the host adapter waits
for a read, write, verify, or seek command to complete before trying the I/O
transfer again. Since this provides a safeguard allowing the system to recover if an
I/O operation fails, it is recommended that you always set the time-out to a value
greater than zero (no time-out).
