13.3.6 Backplane Slot Ordering
The order which the System BIOS enumerates the cards is dictated by the way the PCI Express slots are mapped onto the PCI
Express switch on the backplane. Unfortunately this is dictated by the routing of the tracks from the slot to the switch on the
backplane. The track routing is designed to provide the highest signal integrity possible, and this means that there is not
necessarily a straight mapping between physical slot number and logical BIOS enumeration.

This order was introduced in Revision F of the Express9 G3 backplane. Prior to this the ordering was
as found in the original Express9. The revision can be determined from the backplane serial number, and
the Revision F serial number will always start 163F.
It can be seen from the table that the first card enumerated by the BIOS when using either an Express9 or Express 9-G3 is the
one in Slot 1. However, on an Express11 the first card enumerated would be the card in Slot 11.
The last card enumerated in an Express11 would be the one in Slot 5. If we were using an SBC4 with this backplane then an
XtremeVision-Pro card would be programmed with the IO Enabled BIOS. Additional cards could have their IO requirement disabled.
If Slot 5 is not populated with an XtremeVision-Pro , the card which would require IO would be the one with the highest bus number.
The last slot enumerated in an Express9 G3 by the SBC4would be Slot 6. In the same manner as the Express11 if an XtremeVision-Pro
is placed in this slot it should be the IO enabled card.
It is also worth noting that once booted into Windows the EMS Drivers will reorder our hardware so that it appears in the
order dictated by the jumpers on the card, or by the physical slot if the jumpers are not set. We hide the logical bus order from
the user to simplify the wiring of the inputs and outputs.
