[Request] Unlocked ASUS ROG Crosshair VIII Hero (WiFi) BIOS

As I previously wrote, it is not possible to unlock PCH Fan settings without reflashing.

so can i confirm setup_var_cv SystemAccess 0x0 0x01 0x1 is to show ASPM Support and not something thats going to lock me out,

if anyone else is coming across this and you’re on bios 4501 (19/04/2023) on the asus x570 crosshair hero wifi i can confirm “setup_var 241 37” without the “” will switch ASPM from disabled to auto

very helpful, basically gave me the ability to set my own stuff by setup_var

ifrextractor.exe yourefile.exe verbose
node IFR-Formatter.js yourefile.txt

with Optionally, download IFR-Formatter.js (right-click and Save link as... ) and node.exe. Place them in the same folder as the IFR Extractor output and execute node IFR-Formatter.js yourIfrExtractorOutput.txt in the CLI.

now i can see everything mahahahah!

@Sweet_Kitten wow! glad i didn’t enter this, you’re a sweet loped disguise

danger do not enter setup_var_cv SystemAccess 0x0 0x01 0x1 it will do the following :

The SystemAccess variable is a UEFI firmware variable that controls the access to the system settings. It can have two values: 0 for normal access and 1 for restricted access. If the variable is set to 1, some BIOS options may be hidden or disabled. You can use PowerShell or a Universal Windows app to view or change this variable

so no one knows how to change the Access Level using setup_var ?

why can it not be done with out a flash ?

Access Level is what changes if its visible or not, right ?

Not only access level, there’s at least one more condition that ASUS did preset.

going back to flashing the bios with @MeatWar. so there’s no way this board can be flashed as of yet ? unless I some how magically get flashback working? which would mean pulling sticks of ram and buying a usb drive under 2gb, every usb i have is 16gb and 32gb, i recall flashing this system once before, with a sandisk 16gb, i tried using that very same drive and it didn’t work, i have no way to get to the cmos battery, because the gpu is blocking access, with all the support around the gpu i dont want to play about removing it. i built it, but its not meant to be removed and put back in many times. this really is a massive pain in the power supply.

i have a friend who went to university “learnt computer science” he says, he thinks the files asus use, the .cap files, sent an unlock code to the system, before flashing, maybe there’s away to trick that ? if asus can make and change the firmware, like we have seen from ryzen 2000 to 3000, then 5000, there has to be away, you can’t have that much head room, and not have away to exploit it
