## Enable ReBAR and choose BAR size
After flashing the motherboard with the new UEFI image, you need to enable ReBAR, enable "Above 4G Decoding" (if you have the option) and disable CSM in UEFI setup, and then run `NvStrapsReBar.exe` as Administrator.

For older motherboard without ReBAR support, enablging ReBAR depends on Above 4G Decoding. So if you accidentaly turn it off later and can not POST, you need to clear CMOS. Remember to disconnect wall power before you clear CMOS. The Clear CMOS button present on some motherboards may still keep the current date and time. The current date has to be reset to recover the board. So if needed, you should short the Clear CMOS pin headers (with a screwdriver that is metallic, and the metal is not painted / coated), or by removing the battery for 1 to 5 minutes. Another way is to move the GPU to a different PCI slot, or replace it with a different model, if you have an extra. If you can enter UEFI Setup, you can manually set back the year to a value before 2024, reboot, and restore the year after.

`NvStrapsReBar.exe` prompts you with a small text-based menu. You can configure 2 value for the BAR size with this tool:
