Answer
Most 64-bit cards are 3.3 and 5 volt which allows them to work in
the older 5.0 volt 32-bit PCI slots. 64-bit PCI cards are backwards
compatible with 32-bit PCI slots. Please see the list of indicated
products above that will work in the older 32-bit 5.0 volt PCI
buses.
The motherboard must be fully PCI 2.1 compliant as well.

There are some postings, where a given 64 bit product, doesn't
appear to fit the socket. Sometimes this is due to an error
when milling the edge card.
That said, there is still the issue of available low memory
for use by an add-in card BIOS. That may affect the ability to
boot from the card.
Getting the card plugged in is only part of the story.
