Hello everyone,
pci spec. says that when the 64-bit data path is present on a device but
not connected(as in a 64 bit card plugged into a 32 bit pci slot), that
pci component is responsible to insure that its inputs do not oscillate
and that there is not a significant power drain through the input
buffer.
Does someone tell me if Dec's 64 bit pci bridge (21154 or/and 21554) can
insure that?
thanks
