Time to mod acer insyde bios?

Friends at the sony forum manage to hack the insyde bios to unlock menu:
http://forum.notebookreview.com/sony/473226-insyde-hacking-new-vaio-z-advanced-menu-bios.html

A lot of acer uses insyde bios. Maybe its time to start with acer's thread

But I am stuck at a step and need your help

Firstly, download python to your USB drive (must be version 2.6.1)
PortablePython1.1Py2.6.1 ? Portable Python

Secondly, dump your bios using this: (100% cerdits goes to the author) http://urlisdown.org/Tools/SLIC_Dump_Toolkit/BIOS_Backup_TooKitV2.0.rar
Once you dump it, put the dump on the app directry of the python folder
(X:\PortablePython_1.1_py2.6.1\App ,Where X is your USB drive letter)

Thridly, download the advance menu script on the first page of this post:
http://forum.notebookreview.com/sony/473226-insyde-hacking-new-vaio-z-advanced-menu-bios.html
Put the file in the app directory of python

Now run CMD with admin powers
cd to the app directory of python in your USB drive
and type this:
python advanced_menu.py dump.rom new.rom

You should see a slew of errors:
File "advanced_menu.py", line 82, in
raise ValueError("Invalid VSS signature")
ValueError: Invalid VSS signature

If we manage to solve this error, we might be able to start modding insyde bios
(I heard is quiet easy to solve this error by using hex editor and stuff, which i dont understand )

Thanks in advance

 

I guess there no intrest......

 

Obviously, the script is not flexible enough to work on all computer. You'll need someone with good python programming skill to read the python script to figure out how it work. For example, if current script works with 123 computer, download the 123 BIOS & start debugging the script. When you know how the script works, you will be able to mod any Insyde BIOS regardless brand/model. Writing simple document explaining how to mod Insyde BIOS is good idea too.

 

The script doesn't work, because it is tailored for that one specific model. It uses a fixed offset for the variable to adjust.

Upload your DSDT somewhere (together with advanced_menu.py), and I will attempt to create a version for you.

Or, read http://marcansoft.com/blog/2009/06/enabling-intel-vt-on-the-aspire-8930g/ on how to do it yourself. (Note: Have the EFI specification at hand; InsydeH2O is a Tiano-derived EFI implementation.)

 

does anybody know the patch offset for acer extensa 4630g? patch offset 0x258 does not work....

 

I looked at your BIOS. It does not use a "hidden variable" to show/hide advanced menus - it hides them unconditionally. You need to patch the setup utility itself to reveal them.

 

hi .NetRolller 3D

So, how do patch the setup utility itself?

Thanks

 

i have an acer aspire one 522 model and id like to unlock the advanced settings in bios if possible

heres the link to bios: http://global-download.acer.com/GDF...EONE&Step3=AO522&OS=ALL&LC=en&BC=ACER&SC=PA_7

thanks in advance!

 

Anyone one? How do I patch the setup utility?

 

This error while dumping the setup:
Traceback (most recent call last):
File "dumpsetup2.py", line 282, in <module>
strings = StringTable(pe, STRING_TABLE)
File "dumpsetup2.py", line 42, in __init__
offsets = struct.unpack("<%dI"%count, self.data[16:16+count*4])
struct.error: unpack requires a string argument of length 8389024

help!

 

Hi

I got the bytecode. After that, I have no idea what to do

 

There is dedicated Insyde BIOS mod team at BIOS-MODS. You have better luck there.

 

how did you obtain this?
