Revision
1.3
The PCI-X Slot 6 has been modified to allow a third-party add-in riser card. This slot is capable
of being populated with three types of devices:
•
Standard PCI 133-MHz compatible add-in card
•
1U/1 Slot PCI-X 2.0 Riser card
•
2U/2 Slot PCI-X 1.0 (PCI-X 100) Riser card
If either of the Riser cards is used, the riser card pin-out must match the slot’s modified PCI-X
2.0 pin-out.
