IBM OS/2 Installation
/pcihw
PCI configuration hardware registers. Enables driver to access PCI
configuration hardware registers. This switch is available for some
PCI systems that run into problems when trying to access PCI
configuration space through PCI BIOS function calls. (This is the
default setting.)
/!pcihw
Disables the /pcihw switch. This parameter will cause the driver to
access the PCI configuration space though PCI BIOS function calls.
Adapter ID
/a: n
Adapter numbers are assigned based on BIOS address (starting from
the lowest first) and the Device number (PCI Device number in hex
as seen at the upper right hand corner of the first SCSISelect screen)
if the BIOS is disabled. Built-in single-channel host adapters are
generally assigned ID 0 (zero), as the first found adapter.
Unit Parameters
Replace the italicized letters ( x,y,z ) in the switch descriptions below
with the SCSI target ID(s) of the device(s) that you want affected.
The IDs may be a single ID (x) or a list of IDs (x,y,z). The IDs must be
separated by commas.
/dm: x,y,z
Enables Direct Access Storage Device (DASD) manager support.
Allows
os2dasd.dmd to control the specified target(s) when they are
identified as DASD devices. (This is the default setting.)
/!dm: x,y,z
Disables DASD manager support. Prevents os2dasd.dmd from
controlling the specified target(s).
Caution:
Do not disable DASD manager support to the boot
drive, or the computer will not be able to boot.
