    I was wondering if anyone can help me out with an issue.

    I have an alienware 18, I flashed a vbios from a vbios modder, basically modified version of svl7's vbios.
    I had svl7's vbios running before that just fine.
    After the flash the system does not post. The lights turn on, CPU fan spins up,but does not boot/post

    I tried a power drain, removing CMOS and Power drain, Removing a stick of ram and power drain. Any clue as to what I can do?

    Did you flash the BIOS or the vBIOS?

    Iirc, you should be able to reflash every card, when installing them in slave slot 1 by 1. That worked for the older models m17x and m18x.

    Did you flash one or both cards?
    Primary/Master = Left / Secondary/Slave = Right

    I flashed both cards

    I tried to boot up with one card on the right side, it wouldn't go through.

    removed both cards, the device can boot up (as expected)

    I will try to make it boot with a card on the left side. unless there is a trick i can do in the bios

    I couldn't get it to work with either cards on either side.

    without the GPUs I was able to boot to windows, switch to iGFX.
    Went to device manager, uninstalled hidden devices. It would boot up with a card in either slot. booted to USB to flash older vbios, but it says it cannot see any nvidia GPU. (tested for both primary and secondary) When I booted back to windows and switch to binary GFX, We go back to square 1 with no booting when either card is in a slot

    The AW18 BIOS tends to be a bit finicky from what I've read about it, you could reset the BIOS, do a power drain, then try again to flash.


    But

    flash aw18 unlocked bios with cards removed, set video mode to sg, re-install both nvidia cards, make bootable dos USB key with proper vBIOS and nvflash DOS version, reflash both cards, switch back to PEG mode.
