    Hi,

    Just for kicks I tried playing around with this BIOS, as we know we cannot inject a SLIC into an Intel AMI multi-part BIOS like this mobo has so I used Universal BIOS Backup ToolKit 2.0 (detected as AMI) to dump the clean BIOS into one rom file, I then loaded the rom into AMI Tool 1.61 (detected as AMI) like you normally do and while processing I get "Boot block checksum not valid" (now I get this error when I tried to SLIC my Asus laptop BIOS as well so maybe it's not necessarily an Intel only issue.)

    MMTol is unable to load the rom as well, so is it safe to assume this is not a standard AMI BIOS?
