You are right. just looked at Intel's website for 1Gb cards
and quad adaptors
will work on the lowest end bus PCI-X as well as PCIe x4.
However, the current generation of Intel cards appear to exclusively
use PCIe v2.0 x8
There are some PCIe v1 adapters listed, but I don't know their availability.
That might be an issue with if the PE2900 is PCI-e-gen-1 .
