Welcome to the ReBarUEFI wiki, here you will find guides for adding the module along with the various modifications required on some motherboards for full functionality.

You can find the firmware modification guide starting with Adding FFS module.

If you're having any problems after successfully doing all the required modifications see Common issues (and fixes) before opening an issue.

Over 200 different motherboards have been tested to be working.

@Biogent ASUS P8Z77 WS RX 6700 XT 16GB Y Resume from sleep works. Strange fake (or no 🤔) "CSM disabled - No" but without ReBAR it turns to "Yes" without any changes in BIOS/EFI. There are warning beeps (1 long and 3 short) at startup and black screen due to Windows login screen (possibly to start GPU driver). But no any other errors or issues at all, ReBAR works perfectly.

Can't access bios. My guess is that this ReBAR is also 'enabled' on the integrated GPU (and it does not support it). Can't turn on secure boot.

@SignalSpectre ASUS Rampage IV Formula Arc A770 16GB N Resume from sleep works. X79 only needs DSDT patching if Linux. Don't use an ARC GPU with a 4 core ivy bridge cause no rebar can save you from the bad Intel driver optimization (in Overwatch I lost around 80 fps going from the RX570 to the ARC, in Apex the loss was about 60 fps, all of this with rebar enabled).
