Setting DIP Switch Locate the DIP Switch (SW1) to set the correct configuration for the following purposes: l Flash ROM BIOS Update. l CPU upgrade. l Cache mode (reserved).
POST Checkpoint Codes POST is performed by the BIOS when the computer is reset or booted. POST tests and initializes key components. When a POST routine completes, a code is written to I/O port address 80h. Display this code by attaching diagnostic equipment to I/O port address 0080h. Uncompressed Initialization Codes Code D0h D1h D3h D4h D5h D6h D7h D8h D9h Description The NMI is disabled. Power on delay is starting. Next, the initialization code checksum will be verified.
Power On Self Test POST Phases Every time the system is power on, BIOS executes two types of POST routines: System Test and Initialization System Configuration Verification Test and initialize BIOS for normal operations. Compare defined configuration with hardware actually installed. BIOS Error Reporting If an error occurs before the display device is initialized, a series of audio beeps will be emitted to indicate that a fatal error is detected.
If an error occurs after the display device is initialized, the error message is displayed. A prompt to press will appear with the displayed error message. Error Message 8042 Gate - A20 Error Address Line Short C: Drive Error C: Drive Failure Cache Memory Bad, Do Not Enable Cache.
Invalid Boot Diskette Keyboard Is Locked…Unlock It Keyboard Error KB/Interface Error No ROM BASIC Off Board Parity Error On Board parity Error Parity Error ??? The BIOS can read the disk in the floppy disk drive A:, but can not boot the computer. Use another boot disk. The keyboard lock is engaged. The computer must be unlocked to continue. There is a timing problem with the keyboard. Set the keyboard option in Standard Setup to Not Installed to skip the keyboard POST routines.
