Examples
========
device=VIDE-CDD.SYS /D:IDE-CD
SHSUCDX /D:SHSU-CDH
SHSUCDX finds the first available drive letter and assigns it to device
unit 0 of the driver SHSU-CDH. If there is a second and/or third CD
drive they are assigned to the next available letters in sequence.
Drive letters in use are skipped. The first CD supported by a driver is
device unit 0 regardless of its SCSI address.
SHSUCDX /D:IDE-CD,F /D:?USB-CD,U /D:*SHSU-CDH,W /L:0
Assign drive F to the IDE-CD driver, or abort if it is not loaded. If
the USB-CD driver is loaded, assign it to drive U; else do nothing. If
the SHSU-CDH driver is loaded, assign it to drive W; else reserve space
for it, so it can be loaded later. SHSUCDX will return the number of
drives assigned (or 252 if aborted).
SHSUCDX /L:0
If SHSUCDX is not installed, it will return 255; otherwise the number of
assigned drives (which can be 0). In either case, nothing is displayed.
SHSUCDX /D:CD001,,1,1 /D:CD001,,4,1
SHSUCDX assigns the first available drive letter to device unit 1 of the
driver CD001 and the next letter to unit 4. This allows access to non-
contiguous drive units without having to support un-needed units.
