Know The BIOS Beep Code List -All Desktops

When you power on your computer, the motherboard's basic input/output system (BIOS) first detects the computer's internal hardware configuration and then performs the power-on self-test (POST). The POST executes several diagnostic tests that check the basic functionality of the power supply, motherboard, CPU, I/O Bus Controller, RAM, keyboard, and video components. If the computer passes the POST, it will usually return a single short beep or two short beeps, depending on the BIOS manufacturer. If the POST detects any problems, it will halt the boot process and return an error message either visually on the screen and/or audibly through a series of beeps.

Unfortunately, there is no official standard for beep codes. Depending on the BIOS manufacturer, a keyboard controller failure could be three, four, five, or six beeps. While this document lists common BIOS manufacturer beep codes, you should always consult your motherboard's documentation, the manufacturer's Web site, and the BIOS manufacturer's Web site for a definitive beep code list for your particular BIOS. The information contained in the following lists was gathered from various BIOS manufacturers' Web sites.

http://www.phoenix.com/NR/rdonlyres/81E6C43C-93BD-4097-A9C4-62F05AAD6025/0/biospostcode.pdf

Unfortunately, PhoenixBIOS beep codes are significantly more complicated than other BIOS manufacturers. Instead of a single beep code set, PhoenixBIOS codes consist of a series of beep code sets separated by a short pause. Older Phoenix BIOS Plus and PhoenixBIOS 1.x systems used a series of three sets, while the PhoenixBIOS 4.x systems use a series of four sets. The codes listed below are only some of the more than 100 codes for the PhoenixBIOS 4.x. For a complete list of Phoenix BIOS POST task routines and beep codes, please visit their Web site or review your motherboard's documentation.
