I have a AMI bios v2.3. mobo MSI 945gcm7-f; ms-7507 [v1.0 (?)] I don't have a floppy disk drive. I do have support for booting from USB, i've updated manufactured BIOS through msi liveupdate utility, so it went all automatic, thus i don't know how to proceed regarding 'manually' flashing modded BIOS. I have within the modded bios zip a .230 and .XRM-MS file type. I don't know how to proceed. the help file from my BIOS manufacturer is outdated since it explains using a floppy disk drive. I have digged some MDL forums sections, I read about afudos, flash DOS, usb boot disk. Still helpless.
