Bios Beep Codes

Beep Code Manual
American Megatrends Int. & Phoenix



When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.

AMI Beep Codes
Beep Code Meaning
1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity circuit is not working properly.
3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU has failed.
6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7 beeps Virtual mode exception error.
8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card.
9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty.
10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS.
11 beeps Bad cache memory. An error in the level 2 cache memory.
1 long beep, 2 short Failure in the video system.
1 long beep, 3 short A failure has been detected in memory above 64K.
1 long beep, 8 short Display test failure.
Continuous beeping A problem with the memory or video.



Phoenix Beep Codes
Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps.

Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes. Click here for AMI BIOS beep codes.

Find the Temp Folder in Vista and Windows 7

Vista and Windows 7 don't use the same location for temporary files as XP does. Here's an easy way to get the full path of the Temp folder. Click the Start orb, enter CMD, and press Enter. In the resulting Command Prompt enter the command ECHO %TEMP%. This displays the full path of the actual Temp folder. It will normally take the form C:\users\username\AppData\Local\Temp, where username is your user account name.

One way to view that folder is to use the CD (or CHDIR) command right in that Command Prompt, enclosing the full pathname in quotes if it contains any spaces.

If you want to view the folder in Windows Explorer you may run into one small problem; the AppData folder is marked as hidden. Supposing you can't see that folder, you'll need to do this. Press F10 for a menu in Windows Explorer and choose Tools | Folder Options. Click the View tab. Choose the option "Show hidden files and folders" ("Show hidden files, folders and drives" in Windows 7) and click OK. Now you can navigate all the way to the Temp folder

Clearing Memory Cache

When your computer is running for quite some time, you will notice that it slows down due to idle processes. You can use this method to free up unused RAM and speed up your computer. It requires you to create a desktop shortcut and then open it to clear the memory cache.

First right-click anywhere on the desktop and select New > Shortcut.


Now enter the following line when asked for location of the shortcut and hit Next:

%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks


Give it any name and hit Finish.


Now open this newly created shortcut and you will notice a slightly better performance

configure a SOCKS proxy server

Inspired by my wife's difficulty connecting to the internet due to new security policies at her organization, I decided to try a proxy to allow her to use Windows Live Messenger.


The Linux SOCKS proxy server implementation these days is made under the name DANTE

• edit the config file (/etc/socks/sockd.conf). 
• It is in this file logging is enabled via the syslog mechanism and internal and external addresses are bound. Whereas the internal bindings include a port specification, the external one does not.
   
• The comments are well formed I'd also spend a little time looking them over.
  
  The details:
  

  logoutput: syslog
  
  internal: eth1 port = 1080
  internal: 127.0.0.1 port = 1080
  
  external: 1.2.3.4
  # or
  external: eth0

  To achieve full access (no username/password).
  

  method: username none
  
  # Not using authentication, so unnecessary
  #user.privileged: proxy
  
  user.notprivileged: nobody

  The access controls for sockd daemon are last. They are checked against in the order they appear in the configuration file. Notice, don't open your proxy server to the wild world - you've been warned.The first three directives control which IP ranges that have accesss to the server.
  
  - The from: is were the details of the IPs are added. In my cause it is the IP space the clients live in.
  - The to: option is one of the IPs the proxy server is bound to that the given IP range can speak to. It is set to the addresses Dante/sockd is listening on.
  The last of the three drops any requests that don't match either of the first two directives.
  
  
  

  client pass {
  from:  192.168.0.0/16 port 1-65535 to: 0.0.0.0/0
  }
  
  client pass {
  from:  127.0.0.0/8 port 1-65535 to: 0.0.0.0/0
  }
  
  client block {
  from:  0.0.0.0/0 to: 0.0.0.0/0
  log: connect error
  }

  The next four configuration points control who 'routing'.
  - Requests from anywhere to the loopback addresses are dropped.
  - From the loopback addresses and 192.168.0.0/16 are allowed to communicated over tcp or udp protocols.
  - Finally, drop everything else. 
  
  

  block {
  from:  0.0.0.0/0 to: 127.0.0.0/8
  log: connect error
  }
  
  pass {
  from:  192.168.0.0/16 to: 0.0.0.0/0
  protocol: tcp udp
  }
  
  pass {
  from:  127.0.0.0/8 to: 0.0.0.0/0
  protocol: tcp udp
  }
  
  block {
  from:  0.0.0.0/0 to: 0.0.0.0/0
  log: connect error
  }

• Start Dante/sockd.
  

  sockd -V 
  sockd -d

Restore Panels In Ubuntu Back To Their Default Settings

Messed up your panels in Gnome?

Maybe your new to Ubuntu and accidentally deleted items or the panel itself and now you can't figure out how to get it back.

Sure, you can add a new panel and rebuild it by adding the items back on the panel.
Instead of going through the trouble, there is an easy fix that will restore your panels back to their default settings quickly.

Open up a Terminal window, by clicking on Applications \ Accessories \ Terminal. Or, if you deleted the top panel and cannot access the menus, just press ALT+F2 and in the run dialog box, type gnome-terminal then click on Run.

You can also browse for applications, such as Terminal from the Run window, by clicking on the arrow icon next to 'Show list of known applications" and browse for Terminal.

Once the Terminal window opens, enter the following command at the prompt:

gconftool-2 – -shutdown

(Note: There should be no spaces between the two dashes before shutdown.)

gconftool – -recursive-unset /apps/panel

(Remember: There should be no spaces between the two dashes before shutdown.)

Then enter the next command:

rm -rf ~/.gconf/apps/panel

And enter one more command:

pkill gnome-panel

Both top and bottom panels will appear (if missing) with their default settings. Now you can customize them to your preference and get on with using Ubuntu.
