Hello @bsnider2686 o/

ok i cannot figure out what is wrong i used a bios that was already modded for an x99 deluxe and it worked for rebar but it did not recognize my m.2 drive and it was slightly different pcie options so some of my slots would not work so I know its possible now i tried the patch but could get no where i also tried the modded bios for this motherboard on another post and it just cause no boot no post

yes, to use UEFIPatch, you can use either cmd or powershell “.\UEFIPatch .\file-bios.rom”

it does work couldn’t go to full unlimited but its working i will do some gaming and see how well it does

I was able to extract and modify my dell bios from an exe. I have followed the instructions and modified the bin, but when I flash the bin it is not recognized. I have read Dell accepts exe and rcv, any tips?

@AyieD
Security measures prevents mod files by regular flash tools, your should check for an ME Service Jumper (Dell Optiplex 3090 SFF/MT?), dump bios region, mod and then write it, using Intel FPT tool, alternative SPI IC bios programmer.

I’m following a guide (https://www.youtube.com/watch?v=waIjkovptXA) to enable ReBar on my B450M Gaming, just bought a B580 and I really need it lol. The already modded bios is a bit old, could anyone mod the latest (F67d) with the same patches?
Here the old bios: B450MGMod.64a - Google Drive

Hello @dam ,

Doesn’t the B450M Gaming already have ReBAR (CAM) in the official BIOS?

EDIT: Oh, unless you are using a pre-ReBAR support CPU?

Best regards

this motherboard natively support ReBAR lol as stated 68k, if it still does’nt show, just need to unhide it in the Peripherals setting should be (?).

@dam If you have a ReBAR supported CPU, all you need to do is set Compatibility Support Module (CSM) to disabled and usually the Smart Access Memory (SAM), also known as Clever Access Memory or Resizable BAR option appears. It will be somewhere near to the Above 4GB option.

If you get stuck, I’ll look for pictures.

You mean the section which starts with EACC… ?

Yes, this specific section. Strangely enough, UEFI tool and mmtool_a4 shift this section differently, one is up, another one is down.

It also appears that the sections are compressed, so the “free” space between volumes 01 and 02 does not look like a bunch of FFs.

Base address of EACC is preserved
