Thanks.  However, I don't want to use undocumented calls unless we cannot 
do without them.  What about the `Get DPB' call (Int 21h/AH=32h)?  Can't 
I use the "unit number in the device driver" field there?

Anyway, unless `sync' crashes or causes warning/error messages in some 
environment, I won't be hard-pressed to either use undocumented DOS/BIOS 
calls nor put too complicated code into that function.  If a simple 
enough way exists to compute the drive ID, adding it will be worthwhile.
