Power-On Self-Test

The POST (Power-On Self-Test) is a series of initialization routines and diagnostic tests that the system
BIOS runs when the computer boots. The system BIOS will not boot the operating system if system
memory, the CPU, DMA, or the interrupt controller fails the POST diagnostic tests. POST progress is
indicated by a sequence of codes. If possible, error messages are displayed. No beep codes are sounded.
You should not interpret the failure of one or more POST tests as a hardware, software, or firmware
failure. First, confirm the failure with a "clean" boot:
• Remove all accessories, including RAM boards, floppy drive, port replicator, PC Cards, printer,
external monitor, pointing device, and keyboard.
• Provide "clean" ac power—no auto adapter or unusual ac adapter configuration.
• Press the system-off button to start from a known state.
If the computer fails to boot with a clean boot, it requires repair. If an error message is displayed,
confirm the problem using other diagnostic tools.
The following tables list error codes and error messages. Not all POST messages indicate a hardware,
software, or firmware failure—some messages are informational messages.
