Question

In a BIOS chip, what information is typically kept in the CMOS memory?

I'm sorry, I don't think I made it clear from my question.

I'm trying to find out what information is kept in the CMOS memory, not information about BIOS itself.

Sorry guys (and Girls)

Answer 1

Hi, the BIOS function is simple, it initially runs basic device test programs and then seeks to configure these devices, the system BIOS and the information that is required to configure it are stored on a CMOS chip, the CMOS chip is battery powered, and is rewritable memory, which allows for a BIOS upgrade.
Configuration of the BIOS on a computer is called the BIOS setup, it is also called the CMOS setup. Hope this explains what you are after.

Answer 2

cmos or Complementary Metal-Oxide Semiconductor,is where the bios(basic input output system) uses to store its settings
the cmos stores such settings as hard drive configuration,optical drive settings and most important time and date
the cmos can be reset by moving the jumper(situated next to the cmos retaining battery) from position 1/2 to position 2/3,you should then wait for 20 seconds before returning the jumper to its defualt setting of 1/2
the cmos retaining battery should only be removed in such circumstances as failing to boot after overclocking,but all these tasks should only be carried out by a advanced user
good luck

Answer 3

Go into the BIOS of your computer and you will see what is stored there.

As the BIOS is used to boot the computer, the most important things it need is information about what bootable devices (floppy, hard drive(s), CD drives(s), etc) are attached to the PC so it can access them to boot. It also has to track the amount and type of memory, and the processor.

Most BIOS will also include time and date. Also the ability to password protect the computer at bootup.

Answer 4

appears like the CPU is secure notwithstanding the motherboard has a difficulty. in all likelihood the Flash is having a difficulty. are you able to boot from a CD or Floppy? in case you are able to boot from a floppy then you definitely can burn the hot flash code to the motherboard. Take yet another computing device and get carry of the hot flash from the maker of the motherboard and then setup DRDOS or different DOS OS as well from floppy. Then placed the flash burning application and new flash code on the floppy. a sparkling flash could restoration your problem. Many flash gadgets have documents retention issues at the same time as subjected to warmth over lengthy sessions of time. Motherboard makers will decrease corners by technique of shopping for low rated performance chips to maintain value. Many semiconductor businesses have what's refereed because the "Radio Shack" bin. that's elements that they could have thrown away because they did not meet minimum performance specs, yet rather in the adventure that they labored at room temp at any velocity, they were offered to Radio Shack & others for a fragment of the price for elements that did meet spec.

Answer 5

It has enough memory to hold configuration (setup) info about the computer.

These settings includes date and time, keyboard, HD type, floppy disk type, Quick boot, above 1 MB memory test, memory parity error check, system boot sequence, external cache memory, password checking option, PnP, boot sector virus protection, etc.

Answer 6

Settings on the computer. Things such as your time/date and personal settings.

If your CMOS were to die the computer could not keep up with things that are saved on the computer once you restart it.

Answer 7

All the settings that you are ALLOWED to change are saved in CMOS.

Answer 8

one thing i know.. BIOS password
