You are the genius! I tried yours and it worked great. I then tried 555LE's ROM file but I renamed it to ASUSBIOS.rom. It also worked. So both of yours work!! What happened was that in the same directory, there are the original BIOS file, AC86AA31.rom, and the mod BIOS, AC86AA31_SLIC.rom. The DOS is stupid enough or smart enough that when typing AFUDOS AC86AA31_SLIC.rom /P /B /N it actually picked up "AC86AA31.rom" and flashed it. This is a good lesson learned. Thanks a lot!
Thank you IPMARK. But now I'm again confused. The link you gave me, there is written for bios: "BIOS: EFI (INSYDE)". Is that the same thing as UEFI, because on my MBO site it says "64Mb AMI UEFI Legal BIOS with GUI support"? Also, (the link you gave me) it says: "SLIC: Asus 2.1 Cert: Asus". Is that okay, since I have an ASRock ? Thanks for your time! Greetings to you from Croatia.
