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.
Default Settings You Can Change For The Ultra2 SCSI Adapter
The following two tables show the configuration settings that can be
changed. The first table shows the global settings which impact the host
adapter and all SCSI devices connected to it. The second table shows the
device settings which apply to individual devices.

LSI Logic BIOS version 4.x and above supports SCSI Plug and Play protocol called
SCAM (SCSI Configured Automatically).
LSI Logic PCI to SCSI host adapters always generate parity, but some SCSI
devices do not. For this reason, parity checking can be disabled (Off).
It is not recommended to change the host adapter ID from the default value of 7.
Informs the host adapter BIOS and device drivers to scan the SCSI bus from low
(0 to max) SCSI ID, or from high to low (max to 0) SCSI ID. If there is more than
one device on a SCSI bus, changing the device order changes the drive letters
which are assigned to them by the system. This may change the boot order.
Only used when removable disks are installed.
Defines the cyclinder head sector (CHS) values that are mapped onto an un-
partitioned disk.
