Looks like for some reason the drive number (%dl) didn't get passed
through ARGS (by pmbr.s).
Note that we shouldn't really pass the whole %dx here, as pmbr.s have
different understanding of %dh. You may want to add a xor %dh, %dh
before the store line but after the main.2 label.
Please let us know if this helps or not. Thanks in advance!
Cheers,
