Problem modding logo for CLEVO P640RE

BIOS/UEFI Modding BIOS Modding Guides and Problems
1

Hi,

I have tried to mod the bios for the Clevo P640RE.

I took the source from the XMG site (A clevo reseller) who provide this as thier latest bios update:
https://www.mysn.de/driver/XMG/XMG_P406/…OS_1.05.08a.zip
I modified it using UEFITool 0.21.5 as per guides on this and bios-rom forum.
However when I flash it, it either doesn’t update the image or retains the OEM logo that you would originally see.

Here are the two bios files, with my attempts to mod them:

Perhaps I did something wrong? Maybe the bios is protected? I don’t know.
I also notice that when I flash it gives me a warning saying something about not copying the whole rom as the space available is only 3000Kb or something? I beleive it relates to a line in my batch files:

FLASHME.BAT code:

fpt -f P640RE.8M -l 0x300000 -y
AFUDOS.exe P640RE.5M /p /b /n
AFUDOS.exe /s /shutdown 
 
REM fpt -f P640RE.8M -l 0x300000 -y
REM Call flash.bat
rem fpt /closemnf /y
 
rem Afudos.exe /s /shutdown

@echo off
 
@set BIOS.ROM=P640RE.8M
@if exist MSDM.BIN del MSDM.BIN   
 
:WithoutMessage
 
AFUDOS.exe %BIOS.ROM% /p /b /n /x  %1
 
goto   End 
:End
 

 

Here are the two logos I would like to insert, as close to original format as possible:
640 x 480: https://www.dropbox.com/s/zhmh2rmskoa8orx/8M.raw?dl=0
1920 x 1080: https://www.dropbox.com/s/h1kc9ku9j1cnxle/5M.raw?dl=0

Original OEM logo can be extracted from the first link in the post, or here: https://www.mysn.de/driver/XMG/XMG_P406/...OS_1.05.08a.zip

Thanks in advance.

Have you tried using Intel FPT on this website (see C2 and download version 11.0)?

To mod the logo, and allow itself into the BIOS ROM, you will need to use AMI ChangeLogo 5.0. Remember to mod both logo files or reduce the size of your JPEG if this won’t work.

That might help :slight_smile:
Don’t forget to run as admin, backup using fptw -d my_bios.rom -BIOS and flash using fptw -f modded_bios.rom -BIOS.

Hope this helps!

@Steinberg :
Welcome at Win-RAID Forum!
Since this Forum is not specialized in modding the OEM Logo of Clevo Notebooks, the chances to get help here are not great.
According to my knowledge >this< Forum would be a better source for what you are searching for.
Good luck!

If you should know how to solve Steinberg’s problem, why don’t you post your solution into the Forum?
