BIOS Beep Codes and what they mean

Postby ThEvil0nE » Tue Jun 25, 2002 11:56 am

May not be standard beep codes but are most common. Depending on the BIOS manufacturer, the keyboard controller failure could be three, four, five, or six beeps. Always consult your motherboard documentation
and BIOS manufacturer.

Hope this might help :wink:
GoodLuck!!!

Number of beeps Problem description Troubleshooting recommendation

1
Refresh error Reseat memory or replace with known good chips.
2
Parity error Reseat memory or replace with known good chips.
3
Base 64K memory failure Reseat memory or replace with known good chips.
4
Timer not operational Repair/replace motherboard.
5
Processor error Repair/replace motherboard.
6
8042__gate A20 failure Reseat keyboard controller chip, replace keyboard controller chip, check for a keyboard fuse, or try a different keyboard.
7
Processor exception interrupt error Repair/replace motherboard.
8
Display memory read/write failure Replace video card or video card memory.
9
ROM checksum error/Faulty BIOS chips Replace chips or motherboard.
10
CMOS shutdown register read/write error Repair/replace motherboard.
11
Cache memory bad

Any other beeps
RAM problem Reseat the RAM or replace with known good chips.

:idea: PhoenixBIOS

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 new 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 newer 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.

:idea: Dell BIOS

Because Dell uses motherboards and BIOSs from several manufacturers, their computers use a variety of beep codes. Instead of listing each model's beep codes, links are provided to the support pages of several popular Dell desktops.

Sticky meaning those with "goo" on top of the forum??? That'll work. It is a good reference. I wonder what's that sticky goo made of :roll:

I think they pull :wink: it out of a dumpster behind a sperm bank and and swirl some vegamite in it for color :twisted:

2. If you do know tell -
3. If you think you know refer to 1.
