Memory Diagnostics
If you have relocated any memory addresses, you must
change the addresses to their original locations before
running the memory tests or they will not work properly.
If an error occurs during a memory test, the program displays
this message:
Press to view faulty memory chip.
Press Enter. The program displays a diagram of the main
system board and highlights the faulty memory chip.
Hard Disk Diognostics
Hard disk diagnostic tests may be destructive or non-
destructive. Destructive diagnostics destroy data on the hard
disk, but non-destructive diagnostics do not. Be sure to back
up any data on your hard disk before performing any
destructive tests. The following table lists which tests are
destructive and which are not.
