CMOS or BIOS configuration settings
The Motherboard configuration is stored in the BIOS setup
1. Hardware and software configuration information 2. Application settings 3. Users preferences
firmware chip
Settings on a LAN are not stored in any one place; for disaster recovery planning any configuration information should be written down. Most settings for devices on a LAN come from the DHCP server, so backing up that server would preserve most of the typical LAN settings.
yes it is stored in CMOS
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.
On NVRAM.
On 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".
Boot Configuration Data (BCD)
Most of the configuration information (but not all) is stored in the Windows Registry.
