Nope, it's a new one made for you. You could wait for someone with the same motherboard to come around and try it, but there's no telling how long that could take. fzeven's been modding bioses for a long time. I wouldn't worry about it.
Dear Fzeven! Thanx for your work. Your F7 modded bios for GA-MA790FX-DS5 working perfect. I flashed the bios (under DOS) and my Vista Ultimate 64bit stayed activated. On Everest ACPI is _ASUS_ Notebook. Thank you again. (Sorry for my bad english) descent7
