As for
motherboards with 64-bit PCI slots, there are several.
First off, there
are several Alpha motherboards with 64-bit PCI slots. Then there
are the boards
for the Pentium III processors with the Serverworks chipsets. There are also
motherboards for Athlon-MP processors with 64-bit PCI slots (some
of which are
also 66MHz slots). I know there were earlier motherboards for Pentium II and
Xeon processors with 64-bit PCI slots, but they weren't advertised
in the usual
places as they were more of a specialized board, but they were advertised in
some areas.
The newer non-AGP PowerMac's have a 64bit PCI slot as well.
It's generally the slot in which the video card resides.
Geez...disregard the above as I was a bit quick on the send
button! Too many hours driving today. Anyway, 3 of the 4 PCI slots
in the non-AGP PowerMac's made since the Bllue&White are 64bit. The
first slot, which the video card normally resides in and in which it
is required to reside in for DVD playback, is a 32bit slot which
operates at 66mhz while the other 3 are 64bit and operate at 33mhz
though they also support 32bit cards at 33mhz.
