• Sync Rate [R]
– Changes synchronous transfer rate from the default of 40
Mb/sec to 20 Mb/sec or 10 Mb/sec. Normally left at default for maximum
performance, but can be changed on a device-by-device or bus basis.
• Width (bits) [W]
– Selects 16-bit (WIDE) or 8-bit operation. Can be left at
16-bit for all devices; adapter will negotiate correct width upon connection
to each drive.
• Disconnect [D]
– Allows the drive to disconnect from the host adapter
during transfers. Should be left enabled for maximum performance.
• Read Write I/O Timout (secs) [T]
– Timeout value host adapter will wait for
a read or write to complete to the target device. Should be left at default of
10.
• Scan for Device at Boot Time [S]
– Enables host to scan for the target
device at boot time. Disabling scanning of devices that are not on the bus
can speed up the boot process. Default is enabled for all targets.
• Scan for SCSI LUNs [L]
– Enables host to scan for the Logical Unit
Numbers (LUNs), which are sub-devices behind a single target ID.
