Error Features Cmos checksum error defaults loaded

If you are interested in what is Cmos checksum error defaults loaded, then translated from English this message sounds like “CMOS checksum error, parameters loaded by default “.

To make it clear what I’m talking about, I’ll explain to the reader what is CMOS As you know, today’s computers are difficult imagine without BIOS – a set of programs “sewn” into your hardware a computer. The latter allow you to configure hardware components of your PC, they are responsible for downloading the operating systems and so on.

BIOS settings that the user can change in the BIOS Setup, stored in a separate dynamic memory chip under CMOS (Complementary Metal-Oxide-Semiconductor or in Russian “Complementary Metal Oxide Semiconductor”). Volume the memory of such a chip is usually only 256 bytes, and in it in addition to the settings of your BIOS, a number of parameters of your PC.

For the CMOS chip to remember the specified data, it needs to constant food (albeit in a minimum amount). Last thing implemented by a miniature battery (usually CR2032), which supplies CMOS board for several years (on average 5-6 years). Herself the battery is usually next to the motherboard’s CMOS chip circuit board.

When you turn on the computer, the current amount is compared data in CMOS with a benchmark, and if these amounts are not match, then the user gets a Cmos checksum error defaults loaded.

Also, in rare cases, the cause of the described dysfunction can be influenced by viral programs. What is it means Cos checksum error defaults loaded we figured out Now let’s think about how to fix it.
