Grounding Instructions

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided – if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock.

The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor.

If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the product’s plug. Repair or replace

damaged or worn cords immediately.

Chapter 2: POST Diagnostics

Power-On Self-Test (POST) Errors

Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem.

If a system boot is incomplete (for example, the system is turned off while it is going through the POST), then the next time the system is powered on you may get a message stating that the previous boot was incomplete. The BIOS will revert to safe values for the chip set, caches, I/O components, etc. This provides the best possibility of returning to the Setup routine and to normal functioning, but these values do not always produce maximum system performance. To achieve maximum performance after the BIOS has reverted to safe values, re-enter Setup and select the maximum performance values.

If, for example, the terminal was simply turned off during POST, you can return to the maximum performance values by simply entering Setup and exiting or by rebooting.

During POST, you are asked to press <F1> and boot with the default configuration. If you simply presses <F1> and then do not later return to Setup, the system will boot; but the external cache will not be enabled, even though the default configuration will enable the cache.

2-2 Chapter 2: POST Diagnostics

Recoverable POST Errors

Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. If the Beep Error Codes option is set to ON in BIOS Setup, a series of 2 beeps is issued followed four (4) groups of 1 to 4 tones. These tones correspond to a specific Recoverable POST Error. The table below indicates this correlation. These Beep Codes are to assist in understanding an error in the case where the primary display is non-functional or a non-LCD/CRT.

Error and Beep Codes

The following is a list of the checkpoint codes written at the start of each test and the beep codes issued for terminal errors. Not all Test Points are issued by all of the systems. If no beeps are issued for that code, the Beeps column remains blank. In such cases, rely on the on- screen information.

The BIOS also can issue the following beep codes during POST:

• One long tone followed by three short tones if the video

configuration fails.

• One long tone followed by two short tones if an external ROM

module does not properly checksum to zero.

An external ROM module (LAN or Video board) can also issue audible errors, usually consisting of one long tone followed by a series of short tones.

2-6 Chapter 2: POST Diagnostics

Terminal POST Errors

There are several POST routines that issue a POST Terminal Error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, then writes the error to port 80h and attempts to initialize the video. The handler writes the error in the upper left corner of the screen (using both mono and color adapters). The routine derives the beep code from the test point error as follows:

1. The 8-bit error code is broken down to four 2-bit groups.

2. Each group is made one-based (1 through 4) by adding 1.

3. Short beeps are generated for the number of times in each group.

Example: Test point 01Ah = 00 01 10 10 = 1-2-3-3 beeps

Test Points and Beep Codes

At the beginning of each POST routine, the BIOS outputs the test point error code to I/O address 80h. Use this code during troubleshooting to establish at what point the system failed and what routine was being performed.

If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code (see previous section) and attempting to display the error code on upper left corner of the screen and on the port 80h LED display.

If the system hangs before the BIOS can process the error, the value displayed at the port 80h is the last test performed. In this case, the screen does not display the error code.
