7. Maintenance Diagnostics 7.1 Introduction 8355 N/B MAINTENANCE Each <strong>tim</strong>e the computer is turned on, the system bios runs a series of internal checks on the hardware. This poweron self test (post) allows the computer to detect problems as early as the power-on stage. Error messages of post can alert you to the problems of your computer. If an error is detected during these tests, you will see an error message displayed on the screen. If the error occurs before the display is initialized,then the screen cannot display the error message. Error codes or system beeps are used to <strong>id</strong>entify a post error that occurs when the screen is not available. The value for the diagnostic port (378H) is written at the beginning of the test. Therefore, if the test failed, the user can determine where the problem occurred by reading the last value written to port 378H by the 378H port debug board plug at Mini PCI Slot or by the PIO debug board plug at PIO port. 116
