    How to upgrade graphics card for UEFI windows 8 install


    Hi, I am tring to do a clean install of Win 8 in UEFI mode and can't figure how to get a graphic card to work. Some advise turning off secure boot ( How?), but i can't even get started. When I disable CSM in my Asus M5A97 motherboard, my screen goes blank. I had an Nvidia 7300SE card which needs an upgrade to run in Win 8, but the new drivers wont install in my XP 32 computer. I finally gave up and ordered a new GT220 card which is supposed to work in Win 8, only to discover that it needs new drivers installed too. So, how can I upgrade my card to work in a UEFI installation?
    If I get some one to upgrade the drivers in a Win 7 computer, can I then switch the card over to my computer? Or, can I go into troubleshoot, command prompt during startup and get Win 8 to install the graphics driver before the OS install? It's really a catch 22 situation. You need the new drivers for the install, but can't install them until after the install. I would really appreaciate any advice. Thanks

    I looked at the Owner's Manual for the board, and it looks nothing like the one for my Intel based board (P8Z77). You mention CSM, but I don't see it in the Bios setup.

    But, to start, you are installing Windows 8 using the x64 bit install? Windows won't install in the UEFI configuration as 32 bit.

    To Enable the Windows 8 secure boot, you have to disable the CSM... If you do have it, there should be some options that go with it. The CSM would have most of the options relating to UEFI. There may also be a Secure Boot option which allows for selecting UEFI or Legacy OSes, but it is hard to tell without the actual options you currently show.

    The video card and Windows 8 secure boot is not a driver, but a firmware update. I know EVGA is sending out firmware updates for some of its cards. I do not know if a GT220 is involved. But the board does seem to have, or had, an INT 19 Trap Response, which does seem to deal with OpRoms. Perhaps changing that setting might help.

    Perhaps explaining some of your options on the boot tab of the bios might help. I see it does have the Direct Bios option to go straight into the bios.

    Windows 8 will install with Secure Boot enabled.

    For a test install in a test rig, with GT 220 card, in uEFI mode, with a VGA Monitor, no driver problems.

    I've seen that issue in the past, and it usually comes down to font corruption or incorrect fonts on the installation media (UEFI boot is really sensitive to this, apparently). In both situations I ran into this on, there were fonts from the release candidate on an RTM installation media, causing this exact issue (including working properly when CSM was enabled, effectively BIOS booting, and not UEFI booting).

    Thank you for your thoughful replies. I have struggled on this for 3 weeks now and my mind is twisted into knots. Here's some more info I forgot to include. My current system is Windows XP 32 bit and I am trying to do a clean install on an Asus m5A97 R2.0 board with new OCZ Vertex4 SSD from an OEM Windows 8 64 bit DVD. The disc is a UDF disc,so based on what I've read, I converted it into a bootable (I think) ISO disk which I then sent to a USB drive formatted in FAT 32. I also am getting a" NTLDR is missing" message at startup which leads me to believe that it may not be bootable. Both the IMG 2 ISO program for the DVD, and the Windows 7 USB program let you select a bootable disk and I wasn't sure I should select bootable twice. I may have done it on just one.


    If my understanding of firmware is correct, it goes directly to the graphics card GPU. So, does that mean I can install new firmware on another computer and then transfer the card to mine? Both of my graphics cards work in the new computer until CSM is set to UEFI, but the new one will not work in windows XP, so I assume it's for a 64 bit system. My Bios has an advance mode which has a CSM set up option. Under enable, it selects bios or UEFI automaticaly, and when disabled it is strictly UEFI. I read that to be sure in install under UEFI, it had to be disabled. Again, thanks to all for your help. This seem to be a very helpful group.

    Correct, CSM means BIOS booting, basically. To create boot media, it would benefit from doing so on a Windows 7 or Windows 8 system and following the tutorial here.

    There may be some misunderstanding, and hopefully it isn't me. I may use incorrect words for different things, and as Theog said in an earlier post, the terminology can get a little confusing.

    But on my ASUS (Intel) board, the Compatibility Support Module (CSM) has several settings. If enabled, it allows for UEFI, Legacy, or both types of boot devices. It also has settings for UEFI or Legacy or Ignore, OpRoms for Network, PCIe, and Storage Devices. So why do they call a CSM a Compatibility Support Module? Probably because its purpose is to create compatibility with non-Windows 8 systems.

    Disabling the CSM enables Windows 8 secure boot. The system will not complete the boot process with Windows 7 or with a discreet video card, not even my brand new GTX 680, unless it has UEFI compatible firmware.

    The Secure Boot option below CSM in the setup page has options for Windows UEFI or Other OSes (e.g. Ubuntu).

    The OEMs seem to have done their Bioses or UEFIs (or whatever you call the chip that controls the boot) differently. And they seem to be evolving almost monthly. I believe it is going to be very confusing trying to give guidance on how certain options need to be set, and what they mean when they are. Even the messages you get when you violate the secure boot seems to be different.

    Thanks All again. To theog;That's good to know as I don't even know how to turn secure boot off. To clumerty; Before I discovered the video problem, the boot problem was my main problem and I thought I finally had it solved. I've tried at least a dozen programs that worked for others, but failed for me. I was my understanding that the Window 7 to USB download contained to windows 7 components that would allow me to create a bootable USB as if I had a windows 7 system. And, the USB drive is recognized as UEFI by my board. I don't have access to a windows 7 computer. Saltgrass, I will try to install with CSM enabled. I have tried this before, but can't remember whether it was with a ISO with GPT or UDF and MBR. I've tried so many things, I can't remember. If I can get the system up, I can get new firmware from Nvidia which may work for UEFI. Then, I can re-install with UEFI. Of course, I have Two problems now. It may take a while before I get back, as I only have one power supply and have to switch back and forth. I may also remake my ISO disk and my USB drive. At least I'm not alone now, and that's a real boost to keep going. There's got to be a way.

    ISO's burnt to disc are UDF.

    Legacy Windows install, is MBR.

    uEFI Windows install, is GPT.

    OK! I finally got it working! I couldn't get the USB metnod to work, so I used to ISO disk I made by sending OEM UDF disc to hard drive and then back to disk through an ISO program. I formatted the ssd to GPT and left the CSM enabled. I checked with msinfo32 command and it says it is UDFI and 64 bit so I'm extremely happy! I don't have secure boot, but understand that's not much of a problem and can be turned on after install. I was pretty frustrated by the new system with little things lie
