Already tried flash drive in FAT/FAT32/NTFS, also tried several names for the original BIOS: P8B75-M-LX-ASUS-1002.CAP, P8B75MLX.CAP, P8B75-M-LX.CAP and BIOS.CAP. It seems the onboard EZ Flash 2 has something against me... It currently has v0803, the latest version before v1002. I also tried renaming the BIOS to P8B75MLX.CAP so it would automatically boot to the EZ Flash menu, but that didn't happen. I'm certain about the motherboard version because I have the box in my hands. Any more suggestions?
