Gigabyte GA-MA790XT-UD4P NVMe Mod

Recently i bouth an pcixpress 3.0 adapter with a M.2 kinsgton A2000 ssd, to instal in my Ga-Ma790xt-ud4p but my Bios can’t recognize my ssd, searching in the web i find this page, i need someone to mod my bios to use my old motherborad. The lastes BIos versión is F9b.
I really apreciate the help of somebody because i don’t have enouth money to buy a new computer.

Its a Legacy bios, not UEFI, the regular AMI NVMe mod guide will not work for u.
Try this: [Experimental] NVMe Option ROM
