Someone just told me that to run a PCI card at
66 mhz, all PCI cards in the computer
need to be 66 Mhz. is this true?

if so, where the H am I going to get a
PCI 66 mhz ethernet card and modem?

is a differnt motherboard chipset used
to run PCI66 Mhz? how do I identify
a motherboard that can even handle PCI 66?

Only if they are all on the same bus.

Right now I don't think there are any x86 MB that support 66
MHz PCI except for some server boards ($$$). you will
generally have to look up the MB specs to find this out. I
believe that some of the Alpha 64-bit PCI boards run at 66
MHz. Possibly the SGI Visual Workstation also.

did some searching last night.
the following motherboards claim pci/66 mhz hardware
ASUS P5S-VM
DFI PW65D
?? L440GX+

the last one was second hand info with no manufacturer.
dont know who or what makes it.

then the question is: can any of these run Linux?

I don't think this is quite true.

I am in the process of setting up an old Gateway system with a Promise
Ultra66 card connected to a WD 18 GB Expert drive, and I have a 3-com
ethernet card.

I had to compile Kernel 2.3.8 to get it going, but I have- no problems so
far.
But this is still a work-in-progress.

the following motherboards are the only ones I
currently know of that support PCI/66:

ASUS: P5S-VM
DFI: PW65D
INTEL: L440GX+

you might be able to get it to work, but my
guess is that you'll get the same performance
until you upgrade your motherboard.
i.e. your motherboard will talk to the Promise
card at 33Mhz.

the spec on the Intel board says it has 2 PCI
slots that support PCI/66 and 4 PCI slots that
support 33mhz. and somehow it uses the AGP
to do the PCI/66 stuff. I dunno.
