SCAM Support -
SCAM (SCSI Configured AutoMatically) is the SCSI Plug and Play
protocol supported by Symbios BIOS version 4.X.
Parity -
The Symbios host adapters always generate parity, but some SCSI devices do not.
Therefore, you are offered the option of disabling parity checking.
Note
: When disabling parity checking, it is also necessary to disable disconnect for all
devices, as parity checking for the reselection phase will not be disabled. If a device
does not supporting parity disconnects, the I/O will never complete because the
reselection phase will halt.
Host SCSI ID -
The host adapter SCSI ID should remain on 7 (default), as this setting gives
the adapter the highest priority on the SCSI bus. However, if you have two adapters on
the same SCSI bus, you should give one of them an unassigned ID to avoid duplication
of SCSI IDs.
Scan Order -
This option allows you to tell the host adapter BIOS and your device drivers
to scan the SCSI bus from low to high (0 to max) SCSI IDs, or from high to low (max
to 0) SCSI IDs. If you have more than one device on the SCSI bus, changing the scan
order changes the order in which drive letters are assigned by the system.
