BIOS configuration data is available in several different forms. This data is actively stored on the motherboard of each individual personal computer.
BIOS configuration data is stored in CMOS memory. That is where all the basic hardware settings are kept. CMOS has traditionally been volatile memory, so a battery is required. Newer BIOSes often use NVRAM.
All the settings from the BIOS are stored in a chip which is located on the motherboard. That chip is called EEPROM (electrically erasable PROM).BIOS configuration setting is store in special memory called CMOS. Which is little powered by a battery. RAM is volatile so when computer turned off, all data lost.This can also happen with CMOS but due to this purpose it is powered by battery. It consumption of power is very low and it can store data for 1 year.CMOS stand for "Complementary Metal Oxides Semiconductor".
The Motherboard configuration is stored in the BIOS setup
EEPROM (Electrically erasable programmable read-only memor)
You verify that you have a valid saved configuration for any device on which you intend to modify the configuration
data is saved by storing
The related link has information on the Bios configuration to run the PCSX2 emulator.
In the BIOS setup program.
The bios should just go to your last saved settings if you just close out of it.
The Del key
Boot Configuration Data (BCD)
BIOS stands for basic input-ouput-system and it is how the machine reads and parses data
