Noncritical malfunctions
cause incorrect results that might not be apparent to
the user. An example of a noncritical error is a memory module failure. If a
noncritical error occurs, an error code is displayed, and the testing is
stopped. Testing can be continued on a noncritical error by pressing the
Esc key.
After a successful POST (one in which no critical errors were detected, and
no beep generated), The system attempts to load an operating system. The
system can be customized for different start (boot) methods.
The system’s default startup sequence automatically looks for the operating
system files on the hard disk if the files are not found on diskette.
Note: Remember that the POST does not test all areas, but only those that
allow the system to operate well enough to run the Diagnostics and Utilities
program.
