6 Troubleshooting 84
Verifying proper operation of key system lights
As POST determines the system configuration, it tests for the presence
of each mass storage device installed in the system. As each device is
checked, its activity light should turn on briefly. Check for the
following:
• Does the floppy disk drive activity light turn on briefly? If not, see
"Floppy disk drive activity light does not light" on page 88.
• If system LEDs are illuminated, see "LED information" on page 93
for a description of the light and steps to take to correct the
problem.
Confirming loading of the operating system
Once the system boots up, the operating system prompt appears on
the screen. The prompt varies according to the operating system. If
the operating system prompt does not appear, see "No characters
appear on screen" on page 86.
