The CMOS chip in your computer is backed up by a battery (like a large watch battery) this only kicks in when the computer is switched off. Since the chip requires VERY little power to maintain its settings, the battery will keep the settings for a long time - sometimes years.
What else can I help you with?
Motherboard settings are stored in a small amount of RAM located on the firmware chip and are called?
CMOS or BIOS configuration settings
What should you do if you lose the settings saved in cmos ram?
Nothing, the computer will run fine on the default settings usually.
What component is necessary to save system settings whe you power off the computer?

What is c mos ram?
Cmos ram refers the random access memory used by the cmos which is the primary bios setup on the computer. Most computers use a regular loaded ram to load the basic input output system. The cmos ram can also sometimes refer to the cache that the motherboard has. In general when you mention cmos three things should come into mind. The CMOS battery, the CMOS ram ( stores settings) and the BIOS (basic input output system) Hope this Helps!

firmware chip
Do the bios look to cmos ram settings to find out which secondary storage device should have the OS?
yes
The most reliable way to restore settings is to keep a written record of all the changes you make to?
Cmos ram
Where is cmos setup stored?
Cmos ram.
Why do you have to have CMOS settings?
The CMOS remembers the time and date settings of the computer, and also remembers the Hardware settings.

Yes
What should you do if you get the POST error CMOS checksum bad?
cmos ram might be corrupt. run bios setup and reset bios to default settings. if it occurs again try, flashing bios.
