Hey there, friends. I’ve looked into this online and found several explanations about the CMOS button. On your Asus Dark Hero 1 motherboard, pressing or holding it usually resets the system to its default BIOS settings. It also restores the BIOS version back to the factory level. Clearing the CMOS chip brings everything back to the original factory state, just like when you first installed it.
Regarding your questions:
4. The methods for resetting BIOS differ in how they handle CMOS clearing—options include BIOS settings, physical buttons, or jumper connections.
5. After updating BIOS, whether you load optimized defaults and then configure everything from there depends on the specific BIOS version you’re using.
Thanks again for your questions! Let me know if you need more details.
It doesn't perform a full factory reset of your BIOS. Instead, it removes any custom configurations and brings everything back to the standard settings.
Once it was displayed, all traces of the initial BIOS disappeared and were replaced. To restore it, you'd need to install a previous version of the BIOS.
Thanks for the update, Skiiwee29. It's really helpful to know what's going on. I've been looking for two days now and everyone seems confused about how CMOS interacts with BIOS updates—whether it overwrites your current BIOS or switches to a factory version. There are many mixed opinions online. Your questions are valuable, and I'm happy to help clarify further. Thanks again!
I noticed the same query but different responses from others. It’s important to resolve this so everyone stays clear. I’m feeling a bit confused right now. https://forums.
people are providing unclear and overly complicated responses to what seems like a basic inquiry.
Also @Skiiwee29 Consider using different or same BIOS depending on the issue. If the CMOS button just resets the current version back to defaults, it likely won’t fix a corrupted BIOS. Also, flashing to the same BIOS version is generally safe. (During my update, after finishing I saw no signal on the monitor. After pressing reset everything worked again, but I’m unsure if the installation was complete.)
When BIOS is damaged, posting the system often becomes impossible and may need a USB flashback for recovery if supported, or switching to a different BIOS if available. Issues with faulty BIOS are frequent, particularly with Gigabyte models. Updating to an older or newer BIOS can help, though it isn't guaranteed.
