My motherboard is a Asus Dark Hero


Hey guys, been searching online and got multiple answers on what the cmos button does when you press it/hold it down





1. It resets your motherboard setting to default settings on your CURRENT bios



2. It resets your motherboard bios version to the FACTORY version



3. I clears your cmos chip to factory settings and version just like when you first got it



Also I have a few more questions please to clear up any confusion:



4. Is there any difference between the following methods of resetting BIOS (clearing CMOS) settings:



a.inside BIOS, using option "Load Optimized Defaults" (or, if applicable, load fail-safe defaults)

b. At the back of the motherboard, pressing , Clear CMOS" button

c. On the motherboard, using the (CLRTC) jumper

d. On the motherboard, reseating (not a typo, for non-english speakers) the CMOS battery

e. Reflashing BIOS using the same version



my last question is:



**5. After flashing a newer, same, or older BIOS, is there a need to load optimized defaults and then start setting everything up from there





Thank you again everyone! I appreciate it!

What you ask should be in the manual. The Clear CMOS button clears/reset the bios nvram, which mean that it resets the bios to default settings. It doesn't revert the bios to a previous "factory" version, whatsoever.
