Answer 2

(A) CMOS error is the error presented if you hear a two tone siren beep in Phoenix bios.

Explanation:

• A CMOS Checksum error is a conflict between the CMOS (Complementary Metal Oxide Semiconductor) and BIOS (Basic Input Output System) that happens when you boot up a computer.
• It occurs when the computer isn't able to read startup information or the data does not match up.
• Complementary metal oxide semiconductor (CMOS) is a small amount of memory on a computer motherboard that stores the Basic Input/Output System (BIOS) settings.
• It instructs the computer on how to perform a number of basic functions such as booting and keyboard control.
• It is recommended that you change the CMOS battery every 5 years.
• Open the BIOS screen and note all the information on a piece of paper.
• It's important that you don't make any modifications.
