### Can I use Resizable BAR on my system without modifying BIOS ?
You can use Linux with **4G Decoding on**, recent versions will automatically resize and allocate GPU BARs. If your BIOS doesn't have the 4G decoding option or the DSDT is faulty you can also follow the [Arch wiki guide for DSDT modification](https://wiki.archlinux.org/title/DSDT#Recompiling_it_yourself) using the modifications from [DSDT Patching](https://github.com/xCuri0/ReBarUEFI/wiki/DSDT-Patching) and boot with ```pci=realloc```.

### I set an unsupported BAR size and my system won't boot
Clear CMOS and Resizable BAR should be disabled. In some cases it may be necessary to remove the CMOS battery for Resizable BAR to disable.
