NOTE: This may cause Temp/Permanent Damage to your motherboard, if not done right


WARNING: Do this at your own risk
IDIOT ALERT: Your BIOS must support logos. If u see a nice fullscreen bootup logo, you are good to go. Also if you are not familiar with the terms - BIOS, Flash, Motherboard, Floppy, Recovery. Please DONOT procede


1) Download Archive and extract
2) Covert a suitable image to 640x480 and 256 colors. Save it as a TIFF file
3) Downlad your motherboard's BIOS
No you can't use your friends
4) Open CMD
5) Browse to where you extracted the archive
6) Place downloaded BIOS File here
7) Goto AWBM dir
8) Convert your TIFF file to AWBM Format using the tiff2awbm tool

eg: tiff2awbm logo.tiff LOGO.BMP

9) Copy LOGO.BMP to directory where the BIOS and CBROM215.EXE are
10) Now to see what all your Bios has

CBROM215.EXE Bios.bin /D

If you see something like

LOGO BitMap 7560Ch(469.51K) 039AFh(14.42K) LOGO.BMP

You are good to go.
11) Now to replace your logo

CBROM215.EXE Bios.bin /logo LOGO.BMP

It will now show a progress bar and will complete succesfully

If it shows, not enough space, your image is too complex too fit. Use another image

Also 800x600 Images can also be used, but very few and low detail images will fit into the BIOS ROM. For most images CBROM will say not enough space

This has been tested succesfully on

ASUS A7N8X-E Deluxe
MSI PM8MV

Be extra careful with motherboards that donot have removable BIOS, if you screw up, you are gonna have to pay quite a bit

BTW Thats my logo, feel free to mod it

here is also the 16/10 Intel boot logo I'm using now (white Apple on black background + intel logo)

I hope you guys like these logos. They are pretty simple yet looking nice IMHO

All these logo are 640x480@8bit BMP, cbrom.exe compliant for Award/Phenix Bios.


now, CBROM for dummies :

check with your mobo's vendor / bios revision for compatible CBROM version, find suitable version CBROM.EXE on google and download.
in Windows, run CMD and CD to your CBROM directory, where you also copied your BIOS file to flash and the logo you want to use.

command to add your logo to your bios with CBROM is :

CBROM.EXE biosfile.rom /logo logofile.bmp

biosfile.rom is the bios you dumped from your mobo, or any bios you want to use with your mobo, so change it to the name of your bios file...
/logo is the cbrom switch to add BMP 640x480@8bit logo to bios file
logofile.bmp is your logo, so change it to the name of logo file you want to add in your bios file !

concrete example for my intel mobo :

CBROM.EXE 945gms2.f3 /logo intellogo.bmp

now you can flash the new bios file to your mobo and enjoy your logo.
beware that CBROM overwrites your bios file, so a make backup of it before modding it...
