Описание: Testing if the Gigabyte GA-7ZMM (Socket A / VIA KM133) motherboard actually saves the BIOS date and time after power-off! We set the correct date/time in AMIBIOS, fully power down/unplug the system, wait several minutes (or longer), power back on, and check if the RTC (real-time clock) still holds the settings. Spoiler: Most of these 20+ year old boards reset due to a dead CR2032 CMOS battery or weak retention—watch the before/after results! Includes quick CMOS clear jumper tips (JP3 optional on this model) and battery replacement advice. Perfect for retro AMD Athlon/Duron builders troubleshooting time/date loss.
