its just becouse my application requires 24MB to run acceptable. And I want
to help my customers to WARN them, when they have 32MB of memory, but just
16MB direct physical addressable for OS/2 as memory (the rest as
swapMemory). the difference is about 2 minutes start up time (0:13sec vs
2:04 min).

thx, thats how i have implemented it now. (i'm checking which drives are
available and then i check all drives. is this ok? since this Cat8 call is
for logical drives, so i need to supply a drive id (or a drive handle). so,
when i call it with handle0 and eq: 2 (for 'C') in the parameter block,
what if drive C is on a SCSI drive with a driver supporting 32MB of mem,
but there is a 2nd HD which only supports 16MB DMA). 

 WARPED!, Mario
