    I'm curious about 2 things...

    I did a search and I haven't seen any requests/posts for a Acer 4920 BIOS. Is this BIOS perhaps the same as another here?

    Is there a similar program for editing an Award BIOS?

    I have a Jetway NF-93 mini-itx board that has an Award BIOS that ignores some CPU features and I'd be very interested if there was some way to enhance it to enable these.

    In the mean time , I tried open my bios with PBE 2.2.0.1 - it says BCP not found.
    I tried opening with PBE PRO 2.2.1.3 - it says PSI Aanlysis Fail.
    I noticed that you could not open too another bios for some Aspire new model.
    Phoenix Mod Tool says - bios new style.
    Any progress on this new bioses ? Is there a new utility to open these new bioses?
    And a stupid question - how do you get into Emulation screen in PBE ?

    Thank you

    Hi guys,

    I have collected the BIOS MOD requests which I haven't processed yet. I will working on the oldest first & then on to newer one. Please wait, I'll work as fast as possible.

    @seaman, I already tried to split the Aspire 8942G BIOS image to correct length & offsets but PBE still can't open it. Your only option is by modding (to be exact, re-build) it with Phoenix SLIC Mod tool. You still can follow the tutorial (PDF file) you downloaded earlier. The only difference is you will need to use Phoenix SLIC Mod tool to decompress the original BIOS image & re-build the modified BIOS image after you have modified it. I'll looking into this later.

    Yes, there are software/tools for Award BIOS. To modify Award BIOS, first you will need to understand it's structure.

    Every computer have unique BIOS. Only computer which share the same motherboard & same BIOS chip may share same BIOS image. As for your Aspire 4920 BIOS, I'll look into it later.

    Hey kizwan,

    I have got one question.

    Acer changed the VGA Bios Version (Ati 5650) between the Bios version 1.13 and 1.17.

    Will it be possible to extract the VGA Bios out of the 1.13 and rebuild the 1.17 bios with the VGA bios from 1.13?

    At least we was able to open the bios with the Phoenix Tool after the cut down to 2048KB.

    Thanks

    Yes. Locate the VBIOS in the option rom. When you select any option rom, you will see what it is at the status bar. If it is VBIOS for your 5650, you'll see "ATI" at the status bar.

    Hey kizwan,

    there is no option rom visible in Bios Editor.

    If I open the rom file I get the following errors,
    "An unsupported module class 'Q' was found in file _Q00, do you want to continue?" "Yes/No"

    "An unsupported module class 'H' was found in file _H00, do you want to continue?" "Yes/No"

    "An unsupported module class 'K' was found in file _K00, do you want to continue?" "Yes/No"

    There are 3 modules are under "Other Module", could one of them e the VGA bios file?

    Aspire 7741G BIOS is not compatible with PBE. You still can decompress & re-build with Phoenix SLIC Mod tool. However, it is hard for me to do it since I don't know which option already unlocked & which aren't. It is also hard to re-build with Phoenix SLIC Mod tool since it have limited functionality unlike PBE. Please follow the tutorial (PDF file) to learn on how to unlocked the hidden option yourself.

    I can see one locked option in Aspire 7520 BIOS image which is Processor Assisted Virtualization. I'm not sure which processor do you have & does your processor support Virtualization. If you can install 64-bit OS on VMware Workstation, that mean Virtualization mode is enabled by default. Which means you don't need modified BIOS with Processor Assisted Virtualization option unlocked. If you have any specific request please specify here.

    This is modified BIOS image for Aspire 5930. It based on BIOS v1.23. What changes in this image:-
    Intel SpeedStep menu
    Aspire 5930 BIOS_v1.23 IST MOD.rar

    Please make sure your notebook can recover corrupted BIOS with CRISIS disk before flashing BIOS with this modified BIOS image. I will not responsible for any problem. Good luck. :)
