Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test only our company’s products. Other brand’s products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. 3.
Phoenix BIOS Error Code Messages The following are the list of messages that Phoenix BIOs can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., and the amount of memory installed. Others may indicate a porblem with a device, such as the way it has been configured. The following lists the explanation of the messages and remedies for reported problems.
Error Codes Error Messages Corrective Action 02B0 Diskette Drive A Error 02B1 Diskette Drive B Error Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see that drive is defined with the proper diskette type in Setup and that the diskette drive is attached correctly. 02B2 Incorrect Drive A type - run SETUP Type of floppy drive A: Not correctly identified in Setup. 02B3 Incorrect Drive B Type - run SETUP Type of floppy Drive B: not correctly identified in Setup.
Error Codes Error Messages Press to Setup, for previous Press to enter Setup Optional message displayed during POST. Can be turned off in Setup. Run the I2O Configuration Utility One or more unclaimed block storage devices have the Configuration Request bit set in the LCT. Run an I2O Configuration Utility. (e.g.
Power-On Self-Test (POST) Error Message The POST error message index lists the error message and their possible causes. The most likely cause is listed first. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer.
Error Message List Error Messages Memory size found by POST differed from CMOS FRU/Action in Sequence Run “Load Default Settings” in BIOS Setup Utility.
Index of Symptom-to-FRU Error Message Error Message List No beep Error Messages No beep, power-on indicator turns off and LCD is blank.

LAN-Related Symptoms Symptom / Error Internal LAN does not work correctly.
Intermittent Problems Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1. Run the advanced diagnostic test for the main board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRU. 3.
