The problem is most likely that the vga board that you have is 16-bit,
and the memory address that the wd8013 is at is in the same 128K range
as the 16-bit vga memory.  The MMU on the [34]86 believes that the memory
mapped RAM from the wd8013 is 16-bit accessible.  I've had this problem
here at work.

The kludge solution is to put your vga card in a 8-bit slot.
