If not, see "Diskette Drive Activity Light Does Not Light" on page 89. Does the hard disk drive activity light on the control panel turn on briefly? If not, see "Hard Drive Activity Light Does Not Light" on page 89. Confirming Loading of an 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 "Initial System Startup" on page 85.
