Trying to unlock my bios by following donovan6k tutorial but stuck in assembly code (using IDA PRO)


My problem: - 2 hidden tabs: ADVANCED AND POWER
                    - hidden BOOT MODE (its hidden since i bought with win 7 pre-installed)

BIOS LINK REV 3.7 VERSION 6.30 .  THEY HAVE 2 FOLDERS: Win 7 and 8
DUMP FOLDER IS EXTRACTED FROM folder win 7 x64 (i'm using win 7)

Using Universal IFR Extractor to obtain offset in IFR.txt (attached)


Image BIOS (include where i'm stuck in IDA)


log.pdf file is my reference to know what BIOS has in each tab. Tried to modify individually but i can't boot 'bootx64.efi' in usb to change var.
I found out that it had Boot mode in p.97 and SECURED BOOT DOESN'T INCLUDE.

hope someone find a solution.

Hi Da Vinci Code

I check the result and it runs as 32-bit platform but i'm currently using Win 7 x64
Anyone help me?
I follow this tutorial: http://donovan6000.blogspot.com.au/2013/...tings.html

but I can't run UEFITool.exe to extract the bin file. It suddenly shutdown when im trying to run it.
UEFITool is from CodeRush. http://forums.mydigitallife.info/threads...and-editor


Edit: I can extract the bin file from UEFITool ver 0.30 alpha 19.
