Hi, just modded a bios using the award mod tool. It was an old MSI-7046 board and I thought it would be a good candidate for a mod Anyway all went well, everest says that the SLIC is there and windows 7 works fine and activates, but Vista (a preferred choice for this machine) just says the activation was unsuccessfull, and has the usual 14 days or so to activate. I've checked the SLP, the SLIC and the Certificate and all are ok (I used the same ones to activate another computer) Bit odd, unless I've missed something I thought the SLIC2.1 was backwards compatable. Do I need to do anything special to get Vista to work. Maky thanks in advance.
