I could not find this setting anywhere in my M2N68-AM Plus v0210 BIOS.After some further research I figured that I should perhaps upgrade my BIOS, so I searched and managed to download the latest version (v1804) as a ROM file.
Here’s how to check what BIOS version your computer is using and flash that new BIOS version onto your motherboard as quickly and safely as possible. If your computer freezes, crashes, or loses power during the process, the BIOS or UEFI firmware may be corrupted.
Asus Update is for 32-bit only, AFUDOS doesn't appear to work on my Windows 7 64-bit system (I think it's supposed to run in DOS or something - but that just sounds confusing since I know nothing about DOS). Remember to use a flash drive that is formatted FAT/FAT32 and also rename the file to a short file name such as 1804. ROM file from the file the BIOS downloads from, EZ-Flash does not support ZIP files. (At least for some older BIOS versions.) You must have a FAT/FAT32 (not ex FAT) filesystem.
Highly recommend backing up the current BIOS by hitting the B key, name it something like 0210. Tom, In AI Suite II, click on the update button, then ASUS update. It will ask you how you want to update the bios, and you can select "from the Internet", download the BIOS or whatever.
A BIOS update might be all a user needs resolve them.
Though it's not without hazards, the process is fairly easy. Copy the updated BIOS file to floppy disk or USB drive. When the DOS prompt appears, type the following: afudos /i[name of BIOS file]For example, "p4c800b.rom" might be the name of the new BIOS file.
