Phoenix ISA/MCA/EISA BIOS Beep Codes:
The beep
codes are represented in the number of beeps. E.g. 1-1-2 would mean 1 beep, a
pause, 1 beep, a pause, and 2 beeps.
- With a Dell computer, a 1-2 beep code can also indicate that a bootable add-in card is installed but no boot device is attached. For example, in you insert a Promise Ultra-66 card but do not connect a hard drive to it, you will get the beep code. I verified this with a SIIG (crap -- avoid like the plague) Ultra-66 card, and then confirmed the results with Dell. Submitted by John Palmer.

Codes:
If you know
what these codes mean, plese let me know. If you have an unknown code, please
let me know so I can get it added here.
One beep,
starting out low, then ending high. Submitted by Stu.
Continuous
beeping, each lasting about three seconds. The beeping does not stop. Seems to
be CPU related. Submitted by baders.
Submissions:
- Cold boot only on my new board (Asus P4T-E, bios 1005) I experienced the normal 1 beep and then 5 seconds later, 3 short beeps and then my system went into sleep mode. Changing the Suspend Mode to off OR increasing the # of seconds to enter suspend from default cured the problem. Submitted by Steve Trembley.
- Award BIOS 6.00PG/Asus P4T-E: 4
long beeps when turning on your system might indicate yout CPU fan is
either damaged ot running to slow. Check your CPU fan. Clean or replace it
with a new one.
Submitted by Philipp Golemis - Award BIOS 4.51PG/Soyo SY-6BB:
A repeating high/low beeping. This is due to excess heat alarm. Solution:
Change the settings in the BIOS or add/replace CPU fan.
Submitted by Michel Carlier (Belgium) - Award BIOS/Asus A7V133: Check
"Fan Check Beeping" under the "Power Management"
options in the BIOS.
Submitted by Jonathan Gardner - Award BIOS 6.00/Abit KR7A-133:
One low pitched tone for every 5 seconds, over and over. System boots
fine, but will not reboot from a warm boot. The system will reboot from a
cold boot though. Check the fan speed in the BIOS and change it to a
higher speed.
Submitted by Dave Lowe - NTL - Award BIOS 4.51PG/Gigabyte GA-BX2000: Five short beeps sound when the main BIOS is corrupted and the spare BIOS has to be loaded as only choice for successful boot. Submitted by Andy
