Sorry I forgot to say I tried opening the image with AMI BCP, both UEFI and legacy versions, as well as MMTOOL, and they all spit errors at me "Platform Identification Failed" (UEFI AMI BCP) "Couldn't open the file!" (AMI BCP 3.51) and "Error loading ROM image" (MMTOOL). Which is what lead me to thinking it must be an Insyde BIOS type which I have no tools for. What tool did you use that read the file correctly?
