Expansion
Six PCI 64-bit/33MHz slots on two independent buses:
– pci0: Slots 1 and 2 are reserved for the Core I/O cards
– pci1: Slots 3, 4, 5 and 6
– All of the above slots are not hot-plug capable
Six PCI 64-bit/66MHz slots, each on an independent bus. These are hot-plug capable.
On L1000s only the slots 1, 2, 3, 8, 9, 10, 11 and 12 are usable!
Slot layout (from bottom to top):
1. PCI-64/33, pci0, reserved for core I/O
2. PCI-64/33, pci0, reserved for core I/O
3. PCI-64/33, pci1
