Typically you only need to change the CMOS for diagnostic purposes or when you change a component which is built into the motherboard. For instance, if your motherboard has onboard video or sound and you decide to put in a PCI or AGP card, then the CMOS is where you would disable the onboard functions. Another instance is when you add another hard drive and want it to be your boot drive. If both drives are set to cable select, you can override that setting in the CMOS. For the vast majority of people, CMOS is not something you should mess with unless you are in need of a very large paperweight. Hope this helps.

What enables you to access and modify CMOS data?
To access and modify the CMOS data, you would need a CMOS setup utility. Originally, in the IBM AT and a few close clones, it required a separate utility on a diskette. However, manufacturers soon added this utility the the ROM BIOS. So even today, all you have to do is enter CMOS setup is to press a certain day upon booting the system. Delete, F1, and F2 are some of the common keys to use for entering the CMOS setup utility.
Why do you think the trend is to store configuration information a motherboard in CMOS setup rather than by using jumper or switches?
Because you can change the settings to the CMOS setup by pressing a key or combination of keys during the boot process, whereas you have to open your PC to change jumpers or switches.
What should you do if you lose the settings saved in CMOS Ram because of the bettery going bad or being disconnected?
Reboot with a good battery and instruct setup to restore the default settings. Setup has to autodetect the hard drive present, and than you will need to set the date.
If you need to install an external peripheral to take the place of a failed internal component in a notebook what do you do first to disable the internal components?
First go into CMOS setup and disable the internal device.
If need to install an external peripheral to take the place of a failed internal component in a notebook what do you first do to disable the internal component?
First go into CMOS setup and disable the internal device.
How do you reset CMOS when the computer shows CMOS error in setting?
Your motherboard a CMOS jumper, to find it you need to look through user's manual. Also in user's manual it's written what you need to do to clear CMOS memory.
How do you change Wii fit plus from metric?
You need to change your Country to one that uses Imperial (USA) in the Wii Setup Menu.
If you need to install an external peripheral to take the place of a failed internal component in a notebook what do you first do to a disable the internal component?
To substitute an internal device with an external device, first go into the CMOS setup and disable the internal device.
When trouble shootig a computer why might you have to enter CMOS setup?
When you troubleshoot a computer, there are a number of reasons to enter CMOS setup. Here are some specific situations.1. You may need to change the boot order. If you are having problems with the operating system and you need to install it, you will need to boot off of the installation media. If the machine is set to go directly to the C: drive, then the CD or DVD will never load. But you can change it to boot off of the CD/DVD drive first.2. If the CMOS battery dies. If the battery dies and the settings become scrambled, then you'd need to enter the CMOS settings and fix everything after changing the battery.3. If the computer locks up at random. It is possible that the memory is being clocked too fast or is using the wrong latency settings. In some cases, it may be because someone tried to overclock the CPU. So you can fix any wrong values that cause system instability.4. If you add new hardware devices. You might have to enable a hard drive socket that was disabled. Or maybe you just installed a PCI-e, generation 3 card, but it won't enter generation 3 mode. The CMOS might have a setting to enable that.
What happens when your CMOS battery dies?
I think your new to the system if at all the cmos battery is gone when ever you start the system you can see the system that it directly goes to the bios setup and asks you config the system time,date, need to setup so because of this system will be waiting in that position . if not it will be asking you to press the "F1" or "ESC" key on your keyboard
