Can somebody tell me what exactly is the type of the memory that the BIOS use? I'm wondering if it is EPROM, EEPROM, FRAM or CMOS. Thanks in advance :wink:

Bios is stored in EPROM (old) or EEPROM chips. Configuration Info is stored in CMOS RAM buffered by a small battery. It usually copies parts in system RAM on boot-up.

EEPROM is standard since the late 90's

On VERY old mobos, the BIOS was in a ROM chip.
I´ve several of this on my collection.
