Thanks. Though, I tried NANSI.SYS last night, and hit the same problem.
Already implemented INSB, then hit the DMA word read prob. Implemented
the word read, then hit an even weirder problem. There's execution
of a BOUND instruction check which generates an exception, that
handler of which is the BOUND instruction! Anyone?
