SCAM Support -
SCAM (SCSI Configured AutoMatically) is the SCSI Plug and Play
protocol supported by this Symbios BIOS version 4.X.
Parity -
The Symbios host adapters always generate parity, but some SCSI devices do
not. So you are offered the option of disabling parity checking.
Note
: When disabling parity checking, it is also necessary to disable disconnects for all
devices, as parity checking for the reselection phase is not disabled. If a device does
not generate parity, and it disconnects, the I/O never completes because the reselection
never completes.
Host SCSI ID -
It’s not suggested to change your host adapter SCSI ID (default: 7), as
this gives it the highest priority on the SCSI bus. However, if you have two adapters on
the same SCSI bus, you should give one of them a currently 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 (o to max) SCSI ID, or from high to low
(max to 0) SCSI ID. 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.
