Bios Mods -The Best BIOS Update and Modification Source

Hi there, Id love to change to bootanimation / exchange the graphics in this BIOS.
Sadly I cant find a working "EZFlash", which is described in the manual...it does not recognize the BIOS file,
no matter if its ending is .ROM or whatever....

Its an old Asus Z92J Laptop with an AMI BIOS.

Downloadlink to official BIOS (v217 aka. A6J217AG) :

Currently I use the BIOS A6JCAS.206 : (extracted using Universal BIOS Backup Toolkit)

BIOS 217 only offers Merom CPU support.
I dont need that update and I was just looking for a way to change to bootanimation.

Any reply appreciated
