This eVGA X299 board does have multiple switchable BIOSs to cover for a bad flash, so if you don't mind trying the UEFITOOL method I can give it a try as long as it isn't a permanent mod that can't be recovered by flashing a clean BIOS. If this is a permanent mod, maybe I need to wait for another option. Thanks,
Serg008 please upload Dell vostro 2520 mod. Can this be used to activate Windows 7? Or else please provide mod for windows 7.
It was a personal mod (done from clefranc's PC bios backup) To enable Dell 2.1 SLIC try to use slp utility look here and here for details
