What happens if I put a 64 bit PCI card into a 32 bit PCI slot, will it work
or will the smoke escape from the wires?

Don't worry, I tried it and it worked.

Well, where did you get that card? it's rare. What card is it?
Are you sure your PCI slot is 64 bit? I heard that most slot are 32 bit
only, but putting a 64 bit card in will still work.

A friend bought a room full of stuff at an auction, it was the workshop for
a computer company. It's a scsi card of some sort. I'm certain my PCI slot
is 32 bit but you are correct, a 64 bit PCI card will work in a 32 bit slot.

FYI

I read that like a year ago and looked into many motherboard manuals, they
usually mention that the PCI is a 32 bit thingy. I had never seen one with
64 bit crossing my eyes and i had asked some a old friend of mine, he said
that it's rare to see PCI implemented as 64 bit on ordinary PC motherboard.
 
Ordinary PC motherboards use a 32 bit PCI bus running at 33 Mhz.
64 bit PCI busses are used on server boards, mainly for SCSI adapters, and run at up to 133 Mhz.

I didn't know that. I previously thought they ran at only 33 or 66mhz. One
interesting thing I realised a while ago is that these things don't actually
run at 33, 66, 100 or 133mhz but at 33.3333 recuring, 66.6666 recuring etc.

It's PCI-x. It can also support a much faster bus clock than a normal PCI
slot.

Well in theory it's 33.3333, etc, recuring but in actuality
it's just a multiple of the clock generator which is never
going to be that precise.
