No need to disable BIOS write protection, couse it is read only comand. The extraction should not take more than a minute.
No..Not my first mod..It is an ISA mod (Not with a quickie tool), and I don't think it will brick.. It wouldn't hurt my feelings to have someone else do it though..Just trying to help. I don't usually post these things, but I have gotten so much help with OEM7 mods, Just trying to give back a bit...
