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:
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:
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
@if exist MSDM.BIN del MSDM.BIN
AFUDOS.exe %BIOS.ROM% /p /b /n /x %1
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.
