The calling protocol for INT13h could only handle 127

the high bit of the 8 bit value is reserved for hard disks. Some hardware

Isn't MS-DOS limited to 63 drive letters? (and some versions won't let
you go past 'Z'!)
What OS's have a 14 bit (or 16) for the drive number?
Don't most *nix like system use a 32 bit device number nowdays (those
which still use traditional major/minor device splits), which
depending on the split should give plenty of room.
I wonder what the virtual SCSI adaptor limit is in qemu.... :)
