Thanks rcork, I am not sure if I know which is PM? Is it the CPUpei? ASUSpei? Assuming it is the CPUpei I have 3 roms that where extracted 2 of them 1k and one 13k This is an Asus G74SX ROG laptop. Is there any other way or program for windows or MAC such as otool to decompile this rom other than Linux or MinGW. There is no straight forward instlaller for it, and does not look so easy to get installed in windows. I do use Linux but have to port over the file no biggie I suppose. I do have some assemblers would they do the trick? IDA PRO for example


EDITED A COUPLE HOURS LATER:

I finally found the installer but getting this error:

$osxfr33k@WIN-L8T7CB4LJK2 /c/extract
objdump -m i386 binary -D 2BB5AFA9-FF33-417B-8497-CB773C2B93BF_1_479.ROM > pm
.asm
$C:\MinGW\bin\objdump.exe: 'binary': No such file


When you load the ROM in MMTool, the module will actually be called "PowerManagement"

As for the error you are getting, looks like you're trying this under Windows. I used Linux as objdump is already installed in Ubuntu. Try downloading an Ubuntu Live CD and just boot from the CD and have the ROM on a usb flash drive.

This is suppose to work under Windows VM right? VMware? I am on a real mac with Windows 7 32 bit VMWARE and found a windows installer for MinGW. It installed fine with all the compilers. C C++ Fortran etc.

I do not see anything listed as Power-management when I load the Asus image rom. Some modules do not have anything written by them could it be one of them?

I attached the bios don't know if you want to see what I am seeing?

I think your laptop has a pre 3xxx gen bios, you probably need to edit the cpupei module as per instructions in the Speedstepper thread to get native CPUPM

Unfortunately I cannot find the string that they find over in that thread. There is a 203 bios but I think it is pre as well.

Question why can't the modules be extracted with mmtool instead of phoenixtools?

Thanks

Decompiling the .ROM file is most definitely not a waste of time. How do you think the fix was discovered in the first place? The same string might be present in all ASUS motherboards but it is not necessarily so for other makes. The purpose of the tutorial is to teach people how to manage their own bios if theirs turns out to be different.



First, thanks !!

I will try on my rampage gene IV ( x79) asap !!

So IF I unlock the UEFI from my Asus with 3xxx, On let say a H61 mobo, is the Multiplier / CPU ratio also fully unlocked so I can OC?

Buoo is correct, you use the old method but speedstepping will not work and AICPUPM.kext will kp on boot. Our only hope there is that Apple decide to use Sandy Bridge-E Xeon CPU's in an updated version of the MacPro, which is anybody's guess :worried_anim:

p8h77-m here guys.
I made all changes in the 8C783970-F02A-4A4D-AF09-8797A51EEC8D_1_386.ROM and when pasted in the dump was getting status: failed in the phoenix mod tool. Thought that I did something wrong with the aforementioned .rom file. After scratching my head for a while I tried again without doing any changes in the dump and, to my suprise, It still get failed.
Moreover it fails to re integrate A1902AB9..blah blah.rom

In advanced I only checked the "No Slic" and "Allow user to modify other modules".

Also tried 1.97 of phoenix mod but same happens.

Thanks in advance for any hint guys.
edit: .pic with error.

Hi,

I would like to say thank you for a guide and would like to give few tips to ASUS Z77 owners which can not bypass BIOS security checks. If EZ BIOS Flash fail security checks and it will if you are using bios with modified modules. Flash your bios using ASUS USB BIOS Flashback future.

I can confirm that it works on P8Z77-M PRO with unlocked/modified bios 1303

Thanks!
