the number 57344 is my vga bios size, you have to replace this number
with the size of your vga bios (in boths places of my config: ROM_SIZE
and FALLBACK_SIZE)
I suggest to use awardeco or amideco tool to extract the vga bios from
original bios. The RAM memory dump didn't work for me on epia.
You don't need to pad your vga bios if you use exact size in the config.
