If POST does not detect any errors, the computer will not
beep. This indicates successful completion of POST test. POST has run successfully and
boots from the hard drive (or from a bootable diskette if one is installed in the diskette
drive).
If POST detects errors, the errors are indicated by screen
and/or audible messages. Refer to "Power-On Self-Test (POST) Codes" in the
tables for a list of POST codes and their relevant descriptions.
NOTE:
If the system is not functioning well enough to run
POST, or if the display is not functioning well enough to show POST error messages, refer
to the Troubleshooting tables.
