Intel STL2 manual 4.6Error Messages and Error Codes, 4.6.1POST Codes

Basic Input Output System (BIOS) STL2 Server Board TPS

mode operation, PHLASH (in non-interactive mode only) automatically updates only the main system BIOS. PHLASH senses that STL2 is in recovery mode and automatically attempts to update the system BIOS

Before powering up the system, the user must obtain a bootable diskette that contains a copy of the BIOS recovery files. This is created by running the “crisdisk.bat” from the compressed recovery file distributed with the BIOS.

Note: During recovery mode, video will not be initialized and many high-pitched beep tones will be heard. The entire process takes two to four minutes. When the process is completed, the tones will stop. The user may see a “Checksumerror” on the first boot after updating the BIOS. This is normal and should correct itself after the first boot.

If a failure occurs, it is most likely that of the system BIOS .ROM file is corrupt or missing.

After a successful update, power down the system and remove the jumper from pins 9-10. Power up the system. Verify that the BIOS version number matches the version of the entire BIOS used in the original attempt to update.

4.6Error Messages and Error Codes

The system BIOS displays error messages on the video screen. Prior to video initialization, beep codes inform the user of errors. POST error codes are logged in the event log. The BIOS displays POST error codes on the video monitor.

Following are definitions of POST error codes, POST beep codes, and system error messages.

4.6.1POST Codes

The BIOS indicates the current testing phase during POST after the video adapter has been successfully initialized by writing a 2-digit hex code to I/O location 80h. If a Port-80h card (Postcard*) is installed, it displays this 2-digit code on a pair of hex display LEDs.

Table 4-23. Port-80h Code Definition

Code	Meaning
CP	Phoenix* check point (port-80) code

The table below contains the port-80 codes displayed during the boot process. A beep code is a series of individual beeps on the PC speaker, each of equal length. The following table describes the error conditions associated with each beep code and the corresponding POST check point code as seen by a ‘port 80h’ card. For example, if an error occurs at checkpoint 22h, a beep code of 1-3-1-1 is generated. The “-“ means there is a pause between the sequence that delimits the sequence.

Some POST codes occur prior to the video display being initialized. To assist in determining the fault, a unique beep-code is derived from these checkpoints as follows:
