“I have received many emails and questions in the forum on how to flash the illustrious BIOS. Many people seem in awe of this simple task. ‘What is a BIOS flash? And what is a BIOS,’ some of you might ask. And for some, this may be a no-brainer, but for the new it can be a little daunting. The BIOS is a firmware driven device which controls the functions of your motherboard, and is usually updated as new fixes and new support are added to the features of the board. BIOS stands for Basic Input/Output System. Updating this firmware is a task called flashing the BIOS and is not as hard as it may seem.”

“The Basic Input Output System – aka BIOS – resides in a small Flash EEPROM memory module on the motherboard. It’s a form of read-only memory, but may be rewritten or programmed when the right tools and techniques are applied. During PC startup, the processor on the motherboard always executes the program stored in the BIOS as its first major maneuver.

Anchor Link CMOS Checksum Errors
Information Only Last Reviewed: 2011-02-10
“A checksum is computed as an error-detecting code, to protect the BIOS settings stored in the CMOS memory. Each time the system is booted this number is recomputed and checked against the stored value. If they do not match, an error message is generated to tell you that the CMOS memory contents may have been corrupted and therefore some settings may be wrong.
“The most common cause of checksum errors in CMOS is a battery that is losing power. Viruses can also affect CMOS settings, and motherboard problems can also affect the stored values. Follow the instructions in this section to address the CMOS corruption.”
