Verifying the condition of the storage devices As POST determines the system configuration, it tests for the presence of each storage device installed in the system. As each device is checked, its activity indicator should turn on green briefly. Check the activity indicators for the hard drive(s), DVD-ROM drive, floppy drive, and any other 5.25-inch device you may have installed. If any of these indicators fail to light up, refer to the related problems listed in the "Component troubleshooting" section. 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 the "No characters appear the display monitor" item on page 93. 5 System troubleshooting Component troubleshooting Listed below are specific problems that may arise during the use of your server and their possible solutions.
