Mecer often uses standard OEM boards (e.g., Intel H81, H110, H310 chipsets). If Mecer’s site lacks updates, the original motherboard brand’s BIOS might work, but verify compatibility first.
The system will reboot — it may power cycle a few times. Then enter BIOS and load “Optimized Defaults” (F9), save & exit (F10).
Only when needed. Once every 2–3 years is fine for security, but skip updates if your system is stable.
