The settings in this menu are global settings that effect the selected

 

host adapter and all SCSI devices attached to it.

SCAM Support

The Symbios Logic BIOS version 4.x and above supports the SCSI Plug

 

and Play protocol called SCAM (SCSI Configured AutoMatically). You

 

can turn this off if you wish.

Parity

Symbios Logic PCI to SCSI host adapters always generate parity, but

 

some SCSI devices do not. For this reason you can disable parity

 

checking.

 

 

NOTE

When disabling parity checking, you may have to disable disconnects for

 

certain devices as parity checking for the re-selection phase is not

 

disabled. If a device does not generate parity, and it disconnects, the I/O

 

never completes because the re-selection never completes.
