ePCI-X Bus Details
6.3 PCI-X Bus Signals
Backplane Present
The a_PRSNT# and b_PRSNT# signals are connected to the
Super I/O chip’s GP25 and GP26 pins respectively. These sig-
nal are pulled to +3.3V via 4.7k resistors.
VIO Electrical Keying
The NuPRO-860 monitors the VIO keying signals from the
backplane.
M66EN and PCIXCAP
Only Bus-A supports PCI-X at up to 66MHz. The M66EN and
PCIXCAP signals of Bus-A can be used to program it to PCI
mode.
