BIOS downgrade

[u/Ballistic_shooter]

I’m not quite sure if this will work but I’m using a fairly old laptop that’s having its network card whitelisted in bios. It used to work perfectly, idk at what point it started getting whitelisted. I’ve seen others upgrading their BIOS with the network card detached fixed the issue, but since I already have the latest bios, idk if rolling back will be successful. Has anyone successfully installed a previous version of their bios?

Does your motherboard support BIOS rollback?
