Hi!

I remember seeing this in the documentation and wondering at the
time..."wasn't MCA bus support *dropped* in Windows 2000...?"

I mean, that's what everyone said...yet there remain some curious
vestiges of possible MCA-bus support in Windows 2000 Professional. In
particular, the AHA-1640 SCSI adapter as well as the IBM/Mylex DAC960
RAID adapters (IIRC) still show up as potentially installable
hardware.

I also wonder about those machines that have some kind of mixed MCA
and PCI bus design. Windows 2000 would almost surely run on some of
those...but would the MCA slots be ignored, or handled by whatever
bridge logic connects them to the rest of the system hardware? I do
not have one to try.

Wild Bill, I thought microchannel emulated support for edge triggered
interrupts, AT style interrupt assignments, and in general, is compatible.

Rename the AT bus HAL to MCA?
