The elaborate on my problem:

I installed a Western Digital hard disk controller card into an IBM XT.

To get everything working I had to get into debug and run a program off the
ROM of the Western Digital (WD) card.

It went something like this:

debug
-rax
0000
-0003
-g=xxxx:xxxx    some address on the card.  i don't remember it right now.

Western Digital, copyright . . . . etc

Then proceeded to write its own special stamp the the Winchester.


Well, I turned around and put the IBM hard disk controller card back in the
box to see how it worked and it would not, because WD had put its format on
the disk.

I need to know how to put IBM's special stamp back on this disk.  Hopefully,
the code needed to do the job is at some known address on the card.

Anyone know it?
