[Request] Asus X99-E Rebar support

Hello, i tried to mod the X99-E Beta BIOS 2101 to enable ReBar support, but i failed.

Can somebody please mod the Bios 2101 or 1902 to include and enable the ReBarUEFI driver?

Link to the Bios Versions: https://www.asus.com/de/supportonly/x99e/helpdesk_bios/

It is the Mainboard Asus X99-E NOT X99-E WS.


@Kendoo285 try this: X99EMod.rar (6.3 MB)

Sorry, that bricked my bios. I had to remove the cmos battery, use the clear cmos jumper and i had to remove all my ram to kick in the bios recovery.

Hello @Kendoo285,

Did it not work at all, or after you set a value with ReBAR Sate exe ?

Hello, it did not work at all.

I first flashed the original bios, than i flashed the modded .rom bios with afuwin (GAN support).
After that my computer started with a black screen.

Here is a modified 2101 version. Simple Rebar added with patches
