/PARITY
or
/P Tells the host adapter to disable the SCSI bus data integrity checking feature known
as parity. Some SCSI devices do not generate parity. Valid options are
ON (check
parity), which is the default value, or OFF (do not check parity).
Syntax: / PARITY=n[n]*
To turn off parity checking on the first host adapter (boot order designation = 0), the
line in the
CONFIG.SYS file that loads ASPI8XX.SYS should look like this:
DEVICE=C:[PATH]ASPI8XX.SYS /PARITY=OFF<0>
Warning: When disabling parity checking, you must also disable disconnects for
that adapter since you cannot disable parity checking for reselection. If a device
does not generate parity, and it disconnects, the I/O will never complete.
/EXCLUDE or
/X Excludes support for an adapter that does not currently have BIOS support. Do not
exclude an adapter that is supported (included) by the BIOS when booting the
system. This option has three required parameters that identify the specific adapter
you want to exclude:
• PCI Device ID
• PCI Bus Number
• PCI Device/Function Number
To obtain these parameters, boot the system using the
/VERBOSE command line option (explained later).
The monitor displays the parameters for the adapter or path you wish to exclude.
Syntax: / EXCLUDE[,]*
If the adapter to exclude has PCI Device ID 3, PCI Bus Number 0, and PCI
Device/Function Number 68, then the line in the
CONFIG.SYS file that loads
ASPI8XX.SYS should look like this:
DEVICE=C:[PATH]ASPI8XX.SYS /EXCLUDE<3:0:68>
