ASUS P2B-D2 User’s Manual116
IBM OS/2
Special Unit Parameters:
• /TAG: -- Sets the number (1-16) of tagged commands for all target devices on
the host adapter. A value of one disables tagged queuing 16 is the maximum
number allowed and 8 is the default value.
• /TAG:1 -- Disables tagged queuing for all target devices on a given host adapter.
The driver maintains a maximum of 2 non-tagged commands per target inter-
nally. The driver treats all target devices as non-tagged devices, and sends only
one command at a time per target to the host adapter.
Example:
BASEDEV=AIC78U2.ADD /A:0 /TAG:8 will set the number of tagged commands
for all target devices on the first host adapter to 8.
