You're lucky it worked at all!

I had a Mylex 486/25 in here about 6-8 months ago.  It set records too --
it was the first 486 motherboard here, and the one with the shortest time to
live at this facility ;-)

It didn't pass the DMA test on the 1542B, so back it went.  We got some
"clone" board from an unknown company which worked fabulously (and still
does).
