Driver Installation for OS/2
If OS/2 Warp version 4 is not loaded on your system, perform the installation
procedure in section 6.3.1. If OS/2 Warp version 4 is already installed on your
system, perform the installation procedures in section 6.3.2. For troubleshooting
help, see section 6.4.
NOTE: If you are replacing the host adapter board that is connected to the
computer’s boot device with the QLA2xxx board, you must update the
OS/2 ADD before changing the board.
/SM /!SM This switch enables (/SM) or disables (/!SM) SCSI manager
support for the QLA2xxx board and its attached devices.
Add :d,d,d to the end of the switch to specify a list of SCSI IDs,
or add :(d,d),(d,d),(d,d) to specify ID,LUN pairs. By default, this
switch is enabled.
/!R This switch reports removable disk devices to OS/2 as fixed disks.
By default, removable disks are reported as removable.
OS/2 does not currently support removable disk devices. The
QLogic OS/2 ADD provides limited support for these devices by
treating them as a fixed disks. The disk media must be inserted
when booting OS/2, and the system must be rebooted when
changing the disk media. To enable removable disk support, add
the /!R parameter to the BASEDEV= command in your
CONFIG.SYS file. For example:
BASEDEV=QL21OS2.ADD /!R
/SR /!SR This switch enables (/SR) or disables (/!SR) SCSI bus reset at
power up on the QLA2xxx board. Do not use the disable option
if any device attached to the QLA2xxx board has synchronous
negotiation enabled. By default, this switch is enabled.
/ET /!ET This switch enables (/ET) or disables (/!ET) embedded target
support for the SCSI devices attached to the QLA2xxx board. By
default, this switch is enabled (all eight LUNs are supported).
Specify /!ET for supporting only LUN 0.
/V When enabled, this switch displays configuration data during
power up. By default, configuration data is not displayed.
/RA This switch reverses the order in which the QLA2xxx boards are
configured. This parameter is required on systems with some
versions of access method interface (AMI) BIOS and more than
one QLA2xxx board.
