Hi All!

I'm trying to unlock Resizable BAR for my old GS75 Stealth 9SG laptop (i7-9750H, RTX 2080 Max-Q).

I've been following the steps on https://github.com/terminatorul/NvStrapsReBar and https://github.com/xCuri0/ReBarUEFI.

I've gotten to the point of flashing the new BIOS image/modded with the new NvStraps.ffs file, but I get an error when I use the built in UEFI flasher of "Update Failed - Wrong Image Format 11!"

Using the advanced BIOS options I was able to enable ReBAR for the Intel HD Graphics 630 card but not the RTX 2080 Max-Q. Also changing the Aperture Size to 2048M(from 256M) doesn't seem to change the BAR size reported by GPU-Z or nvidia-smi.

Also - the donate link in the pinned thread isn't working for me (I click it and nothing opens) - so if there's a different link or a direct link needed, please let me know.

My BIOS version is E17G1IMS.111 and can be downloaded from: https://www.msi.com/Laptop/GS75-Stealth-9SX/support?sub_product=GS75-STEALTH-9SG
(the .zip file is too large to be attached)
