    I have a big problem.

    I tried flahsh with external floppy but somethins go wrong.

    Notebook totally died.

    When I push power button nothing happen.

    With hot air I removed bios chip from motherboard. I bought ch341a programmer.

    Now I have two problems:
    - software maybe not recognize chip; it's should be a Winbond 25x80
    - bios file is a .WPH ... software accept .bin or .hex

    Someone can help me ?

    pleaseee

    Can anyone tell me which bios chip is compatible with Acer Aspire 5920G ?

    I'm not able to read on my chip; on internet I found for Phoenix the chip is an Winbond 25X80VS1G.

    Can I use another chip ?

    Hi Everyone!

    Just upgraded my 5720z(zg) - ICL50's gpu ( Dead 8400m GS --> 9600m GT ) and I want to flash BIOS using the v1.45 Black Edition linked on the first page.
    So I managed to download and it may come as a silly question, but how do I flash it properly?

    --------------------------------------------------------------------------------------------------------------------------------------------
    offtopic
    Also bought 2x2gb (800mHz) ddr2 and planning to upgrade the processor too ( T2330 ---> T9300 )
    Any recommendation, suggestions or personal experience?

    ps: I'm kinda new here but I've found a lot of useful and intersting information which helped me alot and I'm very thankful for them.

    Hi everyone,

    I have a Acer Aspire 9920. I bought just a 9600M GT graphics card (VG.9PG0Y.005 Acer Aspire 6930G 6935 nVIDIA 9600M GT 512MB)
    I'm succesfull flashed the modded SBIOS and VBIOS and I have a perfect view on my laptop screen.

    But when I install the NVIDIA drivers I've got a BSOD error or the device can't start (error 43).
    I have Windows 7 64 bit and I tried NVIDIA driver version 275.33 and 309.08

    Is this an hardware issue or can it be an incompatible VBIOS?

    Thanks!

    I did download from above link files:
    icl50_1.45_black_edition_40.fd
    icl50_1.45_mxm_edition_30.fd
    (for Acer Aspire 7720). I did recently update microcodes in original ACER 1.45 BIOS. I did check both files with "Intel Microcode List ver0.4" tool and did get following info about CPU microcodes:
    CPUID=6F4 Rev=26 2006/03/12 CRC=DA8E97D1 Off=C3FA0 Size=1000 Plat=0,2,4,5,6,7
    CPUID=6F5 Rev=38 2006/07/25 CRC=6333B559 Off=C4FA0 Size=1000 Plat=7
    CPUID=6F9 Rev=83 2006/09/28 CRC=85B7E1DF Off=C5FA0 Size=1000 Plat=7
    CPUID=6FA Rev=94 2007/09/24 CRC=613BCE61 Off=C6FA0 Size=1000 Plat=7
    CPUID=6FB Rev=B6 2007/07/13 CRC=2831CEE4 Off=C7FA0 Size=1000 Plat=7
    CPUID=6FD Rev=A3 2007/08/13 CRC=89C0D01F Off=C8FA0 Size=1000 Plat=7
    CPUID=10661 Rev=33 2007/03/16 CRC=9E99CC48 Off=C9FA0 Size=1000 Plat=7
    CPUID=10670 Rev=05 2007/02/09 CRC=7E1FBC19 Off=CAFA0 Size=1000 Plat=7
    CPUID=10671 Rev=106 2007/03/29 CRC=80731B2D Off=CBFA0 Size=1000 Plat=7
    CPUID=10674 Rev=405 2007/07/20 CRC=735D9FE0 Off=CCFA0 Size=1000 Plat=7

    Original 1.45 file:
    CPUID=6F4 Rev=26 2006/03/12 CRC=DA8E97D1 Off=C3FA0 Size=1000 Plat=0,2,4,5,6,7
    CPUID=6F5 Rev=38 2006/07/25 CRC=6333B559 Off=C4FA0 Size=1000 Plat=7
    CPUID=6F9 Rev=83 2006/09/28 CRC=85B7E1DF Off=C5FA0 Size=1000 Plat=7
    CPUID=6FA Rev=92 2007/03/13 CRC=13ED7841 Off=C6FA0 Size=1000 Plat=7
    CPUID=6FD Rev=A3 2007/08/13 CRC=89C0D01F Off=C7FA0 Size=1000 Plat=7
    CPUID=10661 Rev=33 2007/03/16 CRC=9E99CC48 Off=C8FA0 Size=1000 Plat=7
    CPUID=10670 Rev=05 2007/02/09 CRC=7E1FBC19 Off=C9FA0 Size=1000 Plat=7
    CPUID=10671 Rev=106 2007/03/29 CRC=80731B2D Off=CAFA0 Size=1000 Plat=7
    CPUID=10674 Rev=405 2007/07/20 CRC=735D9FE0 Off=CBFA0 Size=1000 Plat=7
    CPUID=10676 Rev=60C 2008/01/19 CRC=FBAC0EED Off=CCFA0 Size=1000 Plat=7

    Now I am a bit confused with those different CPUIDs in original file vs those modified. What was the purpose to change the microcode CPUID=10676 to CPUID=6FB?
    10676 = Core 2 Duo T9300 I have installed in laptop and now I am afraid to use that modified BIOS.

    After extra checking I see 6FB = T7800, T7700, T7500, T7400, T7300, X7900
    So it looks like adding support for some CPUs at cost of other ones (T9300, T9500, X9000). Am I correct?
    Does someone remember why such a change?
    And what is the difference between black_edition vs mxm_edition anyway?

    Hello

    I have upgraded my acer 5720zg with t8300 cpu, new fan, ssd drive and 4 gb ram.

    Next on the list is gpu.
    I found a few comments from NetRoller3D here and there, (mostly on youtube) and ordered compatible cards. It was the only info I could dig up, and I now have two mxm II cards.

    A toshiba gt230m for a500.
    And an Asus gt240m for C90s / M90j

    The Asus gt240m arrives tomorrow, but I just noticed it does not have a bios chip on board, so I suppose it will not work either.
    As far as I know, it is not possible to integrate vbios into the sbios on 5720zg.

    I have ordered bios chips and resistors, I know how to solder the bios chip and resistor onto the gt230m but is there a tutorial or guide on how to solder to the gt240m?

    Any help would be greatly appreciated :)
