Table 4: PCI Bus Configuration and Specifications
Note: (1) All Riser Cards have universal fingers and can plug into
either a 3V or 5V signaling backplane. All cards will operate in 32 or
64 bit slots and 33 MHz or 66 MHz primary bus slots.
(2) Signaling environments cannot be mixed; all components on a
given PCI bus must use the same signaling convention of 5V or 3.3V.
