I have the modifications to WD8003E.ASM to fix the problem with the
microchannel version of the western digital board.  A command must be sent
to register 5 on the new boards to tell them to send interrupts to the
bus.

If someone would indicate an anonymous ftp account that would be appropriate
to store this mod I would be glad to provide the files.
