    If you are interested in learning how to enable VT without modifying BIOS, please read post #1 here:-
    Acer Laptop with Phoenix BIOS: Enable Virtualization (Test Machine: Acer Aspire 9420)

    If you want to learn how to modify BIOS image to unlock hidden menu, please read post #2 in the same thread. I already put the link to original thread by rbjack in the post. I'm not very good in writing step-by-step guide but please read post #37 in the same thread. You should be able to figure out how I locate the offsets by comparing the notes in the post with Acer Aspire 5570/5570z v3508 original BIOS image.

    Good luck. :D

    Tested by ZakMcRofl on Aspire 5652, flash ok but screen stays dark. Had to recover via USB floppy drive.

    @lloco73 can you please add this to the first post? I wonder why there are no PM's on this forum...

    Edit: I analyzed the broken 3.66 mod. There is a typo in this line:
    updated VGA Bios 7600Go (v5.73.22.55.03 --> v5.73.22.22.33) G73M
    correct:
    updated VGA Bios 7600Go (v5.73.22.55.03 --> v5.73.22.55.33) G73M

    The new bios some differences:
    - higher memory clock rate (375Mhz instead of 350Mhz)
    - higher Thrtl voltage (1,1V instead of 1,0V)

    Maybe those are responsible for the black screen / lockup...

    Edit2: I used the PhoenixTool.exe from MDL to insert the modified bios into the otherwise untouched original bios and it was enough to cause the blank screen. Then I used Nibitor to adjust the bios settings to the original GPU bios, did not help either. So the 05.73.22.55.33 is simply not compatible with Acer Aspire 5652.

    @Modders: If you could replace OPROM5.ROM (G73 Rom) in the 3.66 already posted with the original, I believe you could save a lot of time and it should make the bios work. I tried to do that but got size errors that I can't handle.

    ok, read and understood.

    I successfully recovered from the broken 3.66 Acer 5650 bios mod so I have a working CRISIS recovery floppy.

    Here's my request:
    Original bios:
    http://global-download.acer.com/GDF...p3=Aspire 5650&OS=V10&LC=de&BC=Acer&SC=EMEA_8

    If possible:
    - unhide Intel VT menu (priority)
    - update to Acer SLIC v2.1 from slic 2.0

    Bonus (not important, maybe for others):
    - unhide any menus you can find (SATA AHCI, Speedstep. any "harmless" menu)

    RW-Everything-Report and original bios here:
    http://www.multiupload.com/MOAB2NVNRS

    @Modders: See EDIT2 in the post above, if you could replace OPROM5.ROM (G73 Rom) in the 3.66 already posted with the original, I believe you could save a lot of time and it should make the bios work. I tried to do that but got size errors that I can't handle.

    If you can't wait, contact the original modder to do the job for you.

    Firstly, thank you very much for your work. I'm looking forward to testing it out. Getting the "Advanced NB Options" section working at a later time would be great, since I think SidePort memory is causing some problems with the xf86-video-ati driver when using KMS under Linux.

    Unfortunately, I can't get CRISIS to work. The Fn+Esc sequence works, but the Phlash16 (1.6.5.4) included in the package doesn't seem to support the flash chip found on the LT31 (I confirmed this by trying it on a different DOS image). If I replace it with a working version (1.7.0.14), it still doesn't flash. Therefore, I'm a bit leery of flashing your BIOS onto it. Any suggestions?

    EDIT: Yes, I replaced the CRISIS BIOS file. :)

    ssorgatem claimed (post #167) that he can recover corrupted BIOS on Gateway LT31xx. Maybe you could ask him how. :) I'm totally agree that you should worried to flash the modified BIOS. I'm myself has brick my Acer Aspire 9420 a couple of time. Once you get CRISIS disk working, you can proceed flashing BIOS with modified image.

    @ssorgatem, can you share the procedure to recover corrupted BIOS for Gateway LT31xx?

    Hi kizwan, I can wait just fine, I just wanted to do some research of my own instead of sitting around and being a consumer only. No harm in trying to learn new things, right?
    I'm looking forward to your mod.
