You are so right, Ed, and I should have had mu thinking cap on; apologies to everyone for my error. In case anyone is interested in the differences between the two, there's a neat article on Tom's Hardware: http://www.tomshardware.com/2005/11/23/pci_express_battles_pci/. I am used to working with PCI-X in servers (as you point out), and the new(er) PCIe interface is what we are talking about with regard to the Intel 3945. In fact, even in the T43, one of the card slots is CardBus (32-bit) and the other is PCIe (ExpressCard; see http://www.expresscard.org/web/site/standardsummary.jsp).Yes, the basic support for SATA and PCI Express is there, but we are still on the usual catchup trail to the newer stuff (of course, so are the Linux guys - and gals). I think sinfosar as th PCI Express stuff is concerned that our biggest problem is not with the PCI-X architecture per se, but simply the same old "new hardware" issues.Small point - PCI-X is NOT PCI-Express. PCI_Express slots are sometimes shortened to PCI-E.
PCI-X is an adaption of PCI that has been with us in servers for some years, is normally 64 bit slots and often supports Hot-Swap of cards - in other words a faulty card can be "turned off from the operating system" the card removed and a new one installed and then turned back on again - all without having to close down operation of the system.
