Need help with (old) AMI BIOS

Hi,

I have a ASRock 870 Exteme3. It has a AMI BIOS (no EFI) but the boot splash is just ugly, so I decided that I want to change it. Now I googled for hours, hunted old tools and finally found some that worked. The Problem: They don't find the image. So I extracted all modules with MMTOOL (v3.12) and inspected every module by hand but the only images I found are for hibernation.

Does anyone remember how to change the splash screen?

If needed here the BIOS directly from ASRock: http://www.asrock.com/mb/overview.asp?ca...20Extreme3

Thanks for any help.
