POST error codes
Each time you power-on the system, it performs a series of tests that check the
operation of the system and some options. This series of tests is called the
Power-On Self-Test,orPOST. POST does the following operations.
vChecks some basic system-board operations
vChecks the memory operation
vStarts the video operation
vVerifiesthat the diskette drive is working
vVerifiesthat the hard disk drive is working
If the POST finishes without detecting any problems, a single beep sounds and the
first screen of the operating system or application program appears.
Note:
Type2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, and 6348 computers default
to come up quiet (no beep and no memory count and checkpoint code display) when no
errors are detected by POST.
Toenable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
1. Select Start Options in the Configuration/Setup Utility program (see “Setup Utility
program”on page 10).
2. Set Power-On Self-Testto Enhanced.
If the POST detects a problem, an error message appears on the screen.A single
problem can cause several error messages to appear.When you correct the cause of
the first error message, the other error messages probably will not appear on the
screen the next time you turn on the system.
In the following index, Xcan represent any number.
