CHAPTER 4
BIOS SET UP
4.1
BIOS Power-On Self-Test (POST)
During the self-test, errors may occur. These errors are communicated through a series of
beeps. The method of beeps used depends on the BIOS program. For example, Microid
Research BIOS uses a combination of low and high tones. AMI BIOS uses a series of
beeps with different error messages that correspond to the number of beeps heard.
