    Thanks for the info. But by previous 156 making the pubkey, do you mean the first 156 of the SLIC table or the 156 bytes immediately before the 182 bytes of the marker? Sorry for nit-picking but I really don't wanna brick my BIOS!

    Thanks so much! I flashed the modified BIOS and my computer's still working! Vista is still activated and ACPIScope reports that the new SLIC Table is in place.

    Great! Glad to hear it went well. :) The fact that you are still able to activate in Vista proves this method is successful.

    Hi,
    i use the Insyde Bios F16a for an HP Pavilion DV5t. I have to change my mini-pci wifi card (an intel 5100agn) with a broadcom 4311 but this bios has a whitelist and the laptop halts with an ERROR 104 - Unsupported Wireless Device.
    So I ask if it's possible to modify or delete this whitelist, a lot of people have this problem and i will be very grateful to the superhero that will help me in defeating evil Insyde whitelist.
    I've tried changing the SPROMM of the mini-pci broadcom card, but it doesn't work, so the only method is to bybass the whitelist.
    Thanks everyone,

    Nihil

    It is possible (probable) that the tool adjusts the checksum when it saves the bios. It is a bit of a process, I have noticed, to save a bios...even one with no modification. I can imagine that when rebuilding the bios, it may adjust, or at least check them, like cbrom.

    If we add/subtract the modules in the future, without using this tool, it may be advisable to open and close the bios with the tool after the modifications are complete..YA think??:D

    Kind of jumping ahead, have to find how to remove the modules first...Hehe

    Hello

    Anyone of you thought about patching the Insyde BIOS to enable VT-x? I have disassembled the BIOS (Acer 8920/6935) but since it seems like BIOS was written in C and compiled it is not easy to understand all the code. Anyway there are no code fragments which would operate on 0x3a MSR directly, I guess that the BIOS is very generic and such 'extra' functionality can be hold in some table referenced indirectly. It is however easy to find all occurrences of rdmsr/wrmsr...

    Maybe you can recommend me a good x86 disassembler which would separate code form data, create labels for branch opcodes and strings etc? Right now I am using x86dis which - while works - is very simple and doesn't distinguish code from data...

    Good work in the Insyde, guys/gals...

    I have an interest in enambling vt-x on a compaq c700 I upgraded the processor on to a c2d.

    Are any of you interested tracking that down in the bios for me? I extracted per the instructions in this forums, found a plethora of stuff, but I'm not good enough to find where vt-x may specified.

    Thanks all,

    -Z

    Insyde Bios for ACER Aspire 4937G

    Further to my previous post, I have unzip the bios until I see the *.FD file. There is only one bios *.FD file. However, the config file seems to instruct the flash utility not to write to the protected area of the bios.

    Could someone tell me how to verify whether SLIC table / SLP 2.0 is in the bios file already? If it is, how safe it is to change the config to write to protected area of the bios.

    Thanks,

    Kumphanart
