Hm. My understanding was that the AT bus (but presumably not the EISA bus)
or perhaps the (older?) motherboards couldn't *do* DMA above 16MB. I'd like
to be clarified on this by someone who knows --- but do it by mail, because
it's not a Linux question and I can't ask in comp.sys.ibm.pc.hardware (I
don't get it here and if I ask for any more newsgroups in my newsfeed before
I get a real news system going I may end up without *any* feed...).
I *do* know that SCO "Unix" moves stuff below 16MB before doing DMA.
