I want to add a hardware RAID card to this mobo. (The built-in RAID is implemented in firmware, not hardware, and will not work with VMware. I know this is a weak PC for VMware but I've used VMware successfully on even weaker ones.) Suitable RAID cards are normally PCI-e x8. This board has an x16 and x1 slot (as well as two 5V PCI slots). I would be tempted to plug a RAID card into the x16 slot, but I am told by Gateway tech support that the slot is intended for video only and will not work with other types of card. I am wondering if anyone has had any luck bypassing this restriction and getting non-video cards to work in the x16 slot. I suspect the on-board video might get disabled if a card is in the x16 slot, but if this is the case I am wondering if just installing an old PCI VGA card would solve that problem. (The video performance is totally irrelevant as VMware only uses it in 80x25 text mode.) I have also read that the mobo is actually a Foxconn 6100K8MA-RS and that some people have had luck in flashing the non-OEM BIOS. I am wondering if that might also help. I am not totally confident in that because among other things, the 6100K8MA-RS is actually a fair bit different than the C51GU01 (parts in all different places, and different expansion slots). Any info would be appreciated.

WHY would you want to do that?
There is a PCI-Express x1 slot on the motherboard.
Black in color, and in-between the black PCI-Express x16 slot, and a white PCI slot.
Use the PCI-E x1 RAID adapter card in the PCI-E x1 slot, and a PCI-Express graphics card in the PCI-E x16 slot. Sheesh!
A PCI-Express slot is not an evolved PCI slot.
Completely different technologies.
PCI uses a shared Parallel bus architecture, while PCI-Express is based on Serial point-to-point.
So your idea of how to 'fix' your problem, is to use a PCI-E x1 card in a PCI-Express x16 slot, and a PCI graphics card in a PCI slot?
Completely backwards.

PCI-Express x16 slot uses the same lanes from the Northbridge, as the OnBoard video?
UTTER NONSENSE!
The Northbridge chip handles the Faster capabilities of a computer.
Handles the Processor, Ram Memory, and HIGH-SPEED Graphics.
HIGH-SPEED graphics is the Accelerated Graphics Port (AGP) technology, and the PCI-Express technology.
The Southbridge chip handles the Slower capabilities of a computer.
The PCI bus is one of those slower capabilities handled by the Southbridge chip.
The PCI bus is also a shared bus. This slows data down.
The AGP bus, and PCI-Express bus are Not shared. They also have a direct link to the Northbridge chip.
The PCI Bus has to go through the Southbridge chip, which has to go through the Internal Bus, THEN to the Northbridge chip.
OnBoard video, or Integrated Graphics, uses the PCI bus.
When you inserted the PCI-E x1 RAID card in the PCI-Express x16 slot, and a PCI graphics card in the PCI slot, BIOS just assigned another IRQ for the PCI-Express x16 slot.
(Interrupt Request)
No fancy technology going on there.
Backwards technology going on with a PCI-Express x1 card in a PCI-Express x16 slot, though.
I do not concur, and do not think that is a good solution, Kevin.

Thank you for the reply but you misread the original problem. I want to operate a better quality, hardware RAID on this motherboard, and I cannot do that with the x1 slot because *real* RAID cards are normally x8 and would not fit in an x1 slot. Yes, the cheapie I bought as a test would have fit in the x1 slot , but that would not help me because the cheapie also would not function with VMware because cheapie RAID cards are firmware implementations whereas real RAID cards offload the RAID processing from the CPU, so as far as VMware is concerned a cheapie RAID will show up only as separate drives, if at all. By the way, I have on several occasions engineered and built an adapter card from scratch and written firmware and software drivers for them, so I do appreciate the differences in bus topologies. I fully understand that a PCI video card is extremely slow. It does not matter because, as mentioned, the intention is to use this system as a server, so video performance is totally irrelevant. Please read questions more carefully.
!O_O! I see, it has to have more than four 1.5TB harddrives, then?http://www.tigerdirect.com/applications/...
Finally got it through my thick head, and appreciate your response, Kevin. Not a fanboy of server computers. Later, joecoolvette
No problem. I don't touch servers much either - set it up and then forget about it for a long time. I later found out that for only twice as much $ as one of those serious RAID cards VMware will get along with will cost, I could get a used server, with the card already in it, that makes this mobo look like a toy. Ah, the joys of shopping for hardware. Cheers, Kevin.

The mobo's chipset is nVidia GeForce 6100/nForce 410. I'd be interested in anyone having any luck using the x16 slot for anything other than video, not just RAID.
SOLVED.I bought a cheap PCIe SATA "RAID" card to test the scenario before investing $$$$ in a real hardware RAID card.As I expected, plugging a non-video card into the x16 slot caused the system to not boot because the x16 slot uses the same lanes from the northbridge as the on-board video, so the motherboard automatically disabled the on-board video and this caused boot failure due to no video being present.As I suspected, plugging in a video card on the (old-style) PCI bus solved the issue and the system worked fine with a non-video card in the x16 slot. In fact, the system was able to boot from a drive connected on the controller plugged into the x16 slot.Of course, this means you need an old-fashioned PCI video card to get this working, and with such an old video card the rig will not be suitable for modern games or DCC.A minor warning is that the card I tried in the x16 slot is only an x1 card, but I see no reason why an x4 or x8 RAID card wouldn't work the same way.Hope this experience helps someone out there.
