NvramEditor

Edit your motherboard’s BIOS settings as a simple searchable list, and save only what you changed.

HOW IT WORKS

Three steps

NvramEditor works with AMI BIOS. SCEWIN, AMI’s own utility, saves your BIOS settings to a text file. NvramEditor turns that file into a list you can search, edit and compare.

Export

Run SCEWIN to save your BIOS settings to a .txt file.

Download SCEWIN pack ↓

Edit

Open the file in NvramEditor. Search, change options or run Optimize.

Import

Save your changes, then load the file back into the BIOS with SCEWIN.

Step-by-step guide

Before you start. You need an AMI BIOS (most desktop motherboards have one). If SCEWIN says it is not compatible, your BIOS is not supported.

Put the files in one folder

Extract the SCEWIN pack anywhere you like, for example on your Desktop. The folder must contain SCEWIN_64.exe, amifldrv64.sys, amigendrv64.sys, Export.bat and Import.bat. Keep them together.

Export your settings

Double-click Export.bat and click Yes if Windows asks for permission. When it says it is done, a file called nvram.txt appears in the same folder. Copy it somewhere safe. This is your backup.

Open the file in NvramEditor

Open nvram.txt in NvramEditor. Search for a setting, select it, pick a new option and check the block preview before you save.

Save your changes

Save the edited file as nvram.txt in the same folder as the scripts (replace the old one, your backup copy stays safe). Import.bat looks for exactly this name.

Import into your BIOS

Double-click Import.bat and allow it to run as administrator. Wait for it to finish, then restart your PC so the changes apply. Messages are saved in log-file.txt.

If something goes wrong

If the PC will not start after a change, clear the CMOS (see your motherboard manual) or use your board’s BIOS recovery. Common SCEWIN messages:

Unable to load driver Run the script as administrator and make sure both .sys files are in the same folder. Some antivirus programs block the drivers, so check it did not quarantine them.
Platform identification failed Advanced: open Export.bat or Import.bat in Notepad and add /d after /S in the SCEWIN line.
ERROR:57 The file name is wrong or missing. The file must be called nvram.txt and sit next to the scripts.
Cannot update protected variable Your BIOS is blocking changes. On ASUS boards, enable Publish HII Resources (Setup > Tool). On newer boards, also disable Password protection of Runtime Variables (Setup > Advanced > UEFI Variables Protection). Other brands use different names for these options.

Prefer the command line? Run SCEWIN_64.exe /o /s nvram.txt to export and SCEWIN_64.exe /i /s nvram.txt to import, from an administrator Command Prompt. Switches can differ between SCEWIN versions.

FAQ

Good to know

Short answers before you touch your BIOS.

Is it safe to edit my BIOS this way?

NvramEditor only changes a text export on your PC. Nothing touches the BIOS until you import the file with SCEWIN yourself. Keep an untouched copy of your original export so you can always go back, and only change options you understand.

How do I export and import?

With the SCEWIN pack, double-click Export.bat to create nvram.txt, and Import.bat to load your edited file back. Both ask for administrator permission themselves. The full walkthrough is in the step-by-step guide.

Command-line users can run these from an administrator Command Prompt:

# export
SCEWIN_64.exe /o /s nvram.txt
# import
SCEWIN_64.exe /i /s nvram.txt

What does “save only what you changed” mean?

The saved file contains just the sections you modified, so importing it touches only those settings and leaves everything else as it is.

Can a wrong value stop my PC from booting?

Yes, some options can. Clearing CMOS or using your board’s BIOS recovery usually brings it back, but that is not guaranteed on every board. Change a few settings at a time and keep your original export.

What does the $10 service include?

Send your own export on Discord and we set every SCEWIN option for you, then return a file that is ready to import. The app itself stays free.

Does it update itself?

Yes. NvramEditor updates automatically on Windows 10 / 11 (x64).
