    Hi
    I have aspire 7750G-9807 and of course I can't switch between ATI/Intel graphic cards.
    I installed modded bios but I can't find "PowerXpress Setting" option =(
    i changed "Always Enable PEG" to enable - but it doesn't helped.

    Can anyone help me ?
    The powerXpress is just a window where u hav to changed the muxed fixed scheme, look carefully it should be there

    Hi ogwarsaw

    Thanks for your replay.
    But in this section BIOS -> Advanced -> Video Configuration -> Pci Express Graphic

    I have only 3 options
    ASPM: with options (Auto selected)
    1)Disable
    2)L0s
    3)LosL1
    4)Auto

    Peg Workaround: with options (Disable selected)
    1)Disable
    2)Enable

    Always Enable Peg: with options (Enable selected)
    1)Disable
    2)Enable

    And I really can't find any "PowerXpress Setting"

    Thats odd because when i go into my bios the powerXpress option is right under the "always enable Peg". All i know is that this bios has worked great with the 7750g-6662 model and other models not sure how it works with the 9807 model. I would suggest re-downloading and installing the bios and try it again. Make sure you downloaded the bios mentioned previously in the thread you probably accidentally downloaded the wrong one. Let me know how that turns out

    Curious what is your motherboard? I have 7750G-6669 with JE70_HR motherboard.

    Also some have said they first have to install the OEM 1.20 BIOS.

    I just tried update bios again - but nothing changed
    But in device manager I have "Amd Radeon 6600M and 6700M Series" - so I guess I can use only one video card, at least it's not a Intel video card =))

    Wow so what are you worried about u have 2 great cards that are practically the same. I had an intel 3000 and 6650m and all my games only read the intel one till i downloaded the bios so i had a huge problem. Either way u still have to use one card anyways thats what the bios does it lets u only pick one card to use manually. Switchable graphics is suppose to have one weak card for basic use and a strong card for gaming and it was suppose to switch automatically. Guess this function only works good in theory. Im just doing everything on my radeon card i dont even switch to intel even when im not gaming

    I'm a game developer so for me it would be nice to have easy way to check game performance on slow and fast graphic card %(
