To enable rebar you need to use modgrub, follow this guide from step 5. VarOffset of 4g decoding of this board is 0x1.

Thank you for your work. Any chance you can do one for H94 Pro 4? (not the “M” version) Thank you! link to the bios is not the latest one but thats the one i need!
I’m only interested in ReBar option, as i get errors on compiling DSDT and i don’t know how to fix them!

Hello, sorry for the late reply, i’ve been busy irl and i just have the mood to make this one.
Here you go, try this: H97P4Rbar.rar (7.2 MB)
If you successfully update to this bios, could you see PCI Subsystem Settings > Above 4G Decoding in the bios menu?
Thank you!!! Actually no, i will have to use ami bcp to unhide the hidden settings. I will give a try and let you know.
Edit: Yes i can see it.

Please try if the toggle work, just make sure to disable CSM before doing so, use rebarstate for any other card than gtx 16 and rtx 20 series, use nvstrapsrebar for turing cards. I update everything in the bios except mcode for 306C3 since i guess you wont need anything for it
My gpu is a
RX580
It is working even it says : no hardware support, unsupported gpu ? Probably i will install later on the drivers fro Nimez. Thank you for your help!!!
Well it is normal for gpuz to say that, but as long as in Advanced > Vulkan there is no 256MB memory heap, and in adrenaline > performance > tuning, resizable bar toggle is enabled (red), then rebar is working as intended.

I think it needed a couples of reboots. Now i turn on pc and there no 256 memory in vulkan, also Rebar is enabled in adrenaline. Again thank you for your help.
The only problem is black screen till windows loads. I can see the “old bios boot sequence” , press del to enter bios, and have a black screen. I don’t remember now where i read about this problem on this forum!
Maybe try to update the gpu vbios gop to latest available gop? Polaris latest is at 1.70.
Or maybe try to enable igpu to see if it does the same when igpu is used aswell.
