You've gone the wrong route. OS/2 can only support drives up to drive
number 31, the HPFS file system reserves the first 5 bits of the 32
bit sector number to identify the drive, the remaining 27 bits
identify the sector within the drive, giving the max HPFS volume size
of 64 Gig.

I would expect the drive letter sequence to be:-
'X','Y','Z','[','\',']','^','_'.
