Hi,
comparing mbr/mbr.S with mbr/isohdpfx.S i get the impression that
really the sequence of
heads = (stack-16)
sectors = (stack-18)
in isohdpfx.S is wrong.
mbr.s has
sectors = (stack-8)
secpercyl = (stack-12)
and pushes them on the stack in the same sequence: first sectors,
then secpercyl.
isohdpfx.S pushes first the sectors and then the heads, which is the
reverse sequence as its stack address definitions.
Have a nice day :)
Thomas
