Hi I got the SPI PRogrammer and downloaded the EEPROM. I see my original was 6MB but i only had the option of 4MB or 8MB then 16MB. So i chose 8. Is that not correct?

Hi

I've got it by myself because I couldn't wait for your response.
I refered following web-site and could modify my BIOS and succeeded bypassing the whitelist.


https://medium.com/@p0358/removing-wlan-...033a5a5e5a

For the following person, I wrote my knowledge which I've got this activity.

[General knowledge]
(1)BIOS includes various information like Windows License number and so on,
   and the contents are modified by itself.

  ->This means the BIOS binary is different between every environments.
  ->Uploading your BIOS image is risky considering you Windows License number is opened to the world.
(2)UEFI BIOS are consist of regions composed by sections which are compressed.
  ->To modify the contents, it should be uncompressed.

[Procedure]
1.Get my BIOS image
  -> Using SPI flash programmer, read and save to bin file.
2.Modify
2.1 Specify the region where includes whitelist checking logic.
  ->Using UEFITool, open the BIOS file, and search the character string 'unauthorize' coded by unicode.
     You will be able to specify section.
2.2 Extract the section as bin file.
2.3 Open the bin file by HEX editor(I used HxD.)
2.4 Search character string 'WLAN' coded by ascii code.
2.5 Modify flags.
  ->According to above web-site, change two flags 1 to zero.
2.5 Save modified file.
2.6 Replace section.
  ->Back to the UEFITool, and replace the region as modified file.
2.7 Save BIOS file.
3.Write modified BIOS file to the computer.

It takes almost an hour. Let's Challenge!

I couldn't unlock the hidden menus.
Plead tell me how to unlock.

Regards.
