    I found a very cheap 8600M GS and I bought it because it was almost free.
    Can I make the internal display work on this one?
    Thank you guys!

    Install the modded SBIOS - if this results in garbled colors on the screen, then it's doable. If, however, the display remains dark, then it won't work.

    Hi
    I updated bios to icl50_1.45_black_edition_40.fd
    (Acer5720G GF9600 laptopvideo2go version 280.36,T9300) changing
    name to CL50145A.fd and using InsydeFlash. Now have access to the BIOS, I see the logo black_edition but when it logs into the system BSOD appears(SATA Mode:AHCI), when I change to IDE mode, login system stops at the welcome message and then get a black screen
    burned to CD CL50142A.fd recovery was successful but the problem is the same
    I burnt a DVD CL50145A.fd but the restoration has failed
    Where can I get BIOS.WPH, I have only BIOS.fd

    The 5720G has an Insyde BIOS, not Phoenix.

    So, the FD file is just right for recovery. (WPH is for Phoenix BIOSes.)

    Simply rename the FD file to "ICL50HW.FD", burn to a CD, then use Fn+Esc to load it.

    Hi .NetRolller 3D,

    I've been experimenting with Fujitsu-Siemens Amilo A 1667g(Uniwill p50ca) laptop for some time.
    It has MXM1 slot, originally equipped with ATI x700.
    Replaced with -
    HD3850, HD4650 - laptop won't turn on, it behaves like there is short-curcuit.
    x1800, x1900 - works fine, however it detects 5 monitors, which is just weird)
    9600 GT - turns on after ~30 sec delay, boots in BIOS and starts loading OS until OS should switch from text mode to graphics mode - then it just stays black, windows however continues to load and laods successfully, GPU-Z some what identifies video board.

    There is no 'mxm structure is invalid' message, however laptop waits ~30sec with display off, so I figured I've dig in mxm structure..
    So far i've been able to open BIOS with MMTool v3.19 and extract some modules from it, however I can't find mxm structure in it.

    mmtool output -

    PCIAddOnRom - LAN bios


    So.. any advice how to find mxm structure in here?
    Or.. can mxm video card function without mxm structure in BIOS?
    Are mxm structures cross-compatible between different laptops?

    link to my BIOS - http://uniwill.com/UserDownload/P50CA/bios/P50CA_BIOS_107.zip
    Maybe you can take a look.

    Thanks,
    lbr

    orginal Bios 1.45 - driver 280.36 works perfect
    1.45_black_edition -driver 280.36 = Black screen
    driver 257.21 works good with B.edition

    NetRolller 3D- Can you unlocked EIST in your acer
    I don't see this option in my bios

    @paymey: You likely have a short on the DVI connector, causing the driver to always detect a DVI display plugged in - check with a multimeter.

    @lbr: I think I posted a BIOS for the A1667G earlier in this thread. If not, I'll post it soon.

    Forgive me NetRolller 3D, but I don't understand the answer to my question.
    we have almost the same Acer and I wanted to know if you can disable the Enhanced Intel SpeedStep ® Technology (EIST) in your BIOS.

    I made my own Modified INF for 280.26 they work perfectly

    In Advanced CPU configuration, disable "IST Configuration" ("Enabled" actually means "enabled and locked", while "disabled" is "disabled and unlocked", meaning that you can still re-enable it with ThrottleStop, allowing for dual-IDA).

    @lbr: Link fixed.
    I can't remember exactly which component I modded - I basically added a new interrupt handler for the MXM interrupt.
