   And it's possible that the unit you have is bad; I've been
debugging a problem with a 946 where it would lock up like a
drum if I ever did DMA(*) across the bridge to the ISA bus. After
checking every possible other approach (disks?  cabling? system
board?) it became apparent that it was the 946 that was having
trouble (I have two of them side-by-side, and the DMA lockup
was following one of the cards; after I bought a third card and
swapped out the offending one, the DMA problem seems to have
stopped.)


   (* or, for that matter, anything that pumped a lot of bytes
across the ISA bridge; I was getting the lockups when I fired up X
or displayed graphic images on the console, and these lockups
ceased when I bought a PCI graphics adaptor and moved video onto
the PCI bus.)
