Thanks to Busykid508 for the ASROCK A780GMH mod! I successfully activated Win7. I have the version 1.20 modded BIOS and the manufacturer has the newer version 1.50. My question is this, after successfully activating WIN7 on the 1.20 mod BIOS ver. can I update my BIOS to 1.5 orig. manuf. ver. (it will erase the SLIC file I think) and still have Win7 working? I appreciate a response, thanks.
