Hi Guys. Your forum has been a life saver for me in the past, so I thought I'd ask a quick question about Windows 7 (any OEM version actually). I have a family member that has a Compaq presario model sr5605f. This system is apparently currently running Vista and they want to install Windows 7. Wouldn't it take an OEM installation of 7 without a slip 2.1 mod because it already has an OEM version of Vista? If it will not take an install of 7, I would need a slip 2.1 modded bios, but I cannot seem to find anyone that has that one available. I would try moding it myself, but it appears the bios you download from the manufacturer is an .exe and I have no idea how to work with that. Any help would be appreciated.
