You could swap out the main board as that should be the only difference.
Except it isn't, because the interface board (with the PCI slots) is different also:

Note:
Figure 2-5 depicts the interface board in a 2- or 4-processor workstation. The
interface board in a 1-processor workstation has 4 PCI-X slots (3 available) and 1 XIO slot.
So the 2-4 CPU Tezro has 8 PCI slots, and 2 XIO slots. The single CPU version has half of everything. And one PCI-X slot is unavailable, probably because it's taken by the IO9. That only makes sense if you eliminate one of the two XIO-to-PCI-X bridges. Maybe cost saving, maybe a necessity. If you look carefully, the dual and quad CPU IP53 boards have *two* high density connectors near the front which connects to them to the interface board. A Fuel has one (and 4 PCI slots and one XIO slot!).
So either:
1. The single CPU IP53 nodeboard doesn't have what it takes to talk to dual XIO-PCI bridges. They produced a reduced cost interface board with less components.
2. The single CPU IP53 nodeboard doesn't have what it takes to talk to dual XIO-PCI bridges but it wasn't worth redesigning the interface board. It's all there, but only half of it works.
I'd like to see some pictures and a hinv from this system. But I wouldn't want to sink my own money into it, nor would I assume upgrading it to a quad config is simply a matter of replacing the nodeboard.
EDIT: OK, Diegel beat me
And indeed the INT53 board is different:
Code:
Select all
Location: /hw/module/001c01/IXbrick/xtalk/15
WS_INT_53_1P Board: barcode MYR049 part 030-1874-006 rev -A
So, are the PCI slots populated at all?
Octane 2, Dual 600MHz R14k's, 2GB, v12
Origin 2200, Dual 300mhz, 2GB
Onyx2
