I think X11SPM8_615.zip is the one we are after
SuperMicro is being of no help to me, so I downloaded all the files from their website including those that were not indexed. Could someone help me figure out what the BIOS versions of all these files are? These are all the files I could find for the X11SPM-TF and X11SPM-TPF.
