Which chip is used to store information that describes specified device parameters?
CMOS chip
What is cmos used for?
C MOS is the complementary metal -oxide semiconductor which is used to hold dates, time and system setup parameters.
Why does a computer turn on if the CMOS battery is removed?
Removing the CMOS battery will not prevent the computer from turning on, it will only cause the information in the CMOS RAM to be lost (while the computer is turned off). When you turn on the computer after the CMOS battery has been removed, while it will turn on it will most likely not boot the OS correctly but will stop in the BIOS and require you to completely setup the CMOS parameters again before you can tell it to continue..
When is necessary to change CMOS parameters?
It's simple about that changing the parameter of CMOS. When you have to install Windows or OS, you have to change CMOS parameters. Otherwise, you have to change something, such as first boot device and second boot device. CMOS can perform some function to block the autorun function from USB port. Thus, your computer may have good security. And you can also change to control some parameter for your computer's hardware devices, like Fan,temperature and so on... That's all I remember about that. Thank you everyone who ask this question. - Aung Zin Linn (I.D.C.S student, Ygn)
Where are post instructions stored?
Power On Self Test instructions are part of the BIOS that is stored in EPROM. Some of the parameters used by the EPROM are stored in the BIOS CMOS chip.
What is the recommended CMOS setting for IDE hard drives?
For almost all modern computers and hard drives, the only settings you should set is for the parameters of the disk to be detected automatically.
Will system boot up normally to operating system level if CMOS battery is dead?
CMOS holds many of the boot parameters, such as what type and size of hard disk, the type and speed of the processor and other critical information. Many times the computer can still boot with a dead CMOS battery, but the information will not be available and will affect the process. Replace the battery then run through the setup procedure to save the values.
What is a CMOS socket?
A CMOS socket is to plug a CMOS transistor into. Alternatively, a CMOS socket is to plug a CMOS integrated circuit into. CMOS, by the way, stands for, "Complementary Metal Oxide Semiconductor".
Where is cmos setup stored?
Cmos ram.
Where does the CMOS password appear?
Modern PCs store the CMOS password in the CMOS memory itself.
Do you need a cmos battery for your computer to boot?
Most new computers can automatically determine the correct settings needed for your hardware, and some even store configuration data in a non-volatile Flash chip. These computers effectively do not need a CMOS battery for anything except maintaining the correct time. Older computers, where you had to specify the parameters for the hard drive in the BIOS, need a CMOS battery. Otherwise, you would have to enter them in every time you booted the computer.
What the function of cmos?
CMOS (Complementary Metal Oxide Semiconductor) is a technology for making solid state devices such as integrated circuits. People who aren't electrical engineers are probably most familiar with the term from its use in the part of a computer that stores configuration information. CMOS devices use less power to maintain their state than do alternative technologies such as TTL and NMOS, making a CMOS memory chip a good place to keep data that needs to be retained even when the computer is turned off and unplugged (a small battery is used to supply power to the CMOS chip). The CMOS settings include things like the parameters for hard drives (more important in older drives, when autodetection was less common and the number of cylinders, heads, and sectors often needed to be set manually) and information about on-board devices that need to be accessible before the operating system itself is loaded.
