While I was inspecting POSReady2009 for some information I stumbled upon OEMBIOS files that caught my eye. Not only I was surprised to find them on this edition but the signature of oembios.cat appears to be invalid. What am I missing here? Which is the Marker string of this version of OEMBIOS.DAT? Source is an untouched iso (0E9E37F9268BBB7181E0A1AE561C178382CC3014) and it's easy verificable by extracting setup.wim without installation. Thanks
