1. If an error is detected on the system test, memory test, display
test, or real timer test, perform the system board isolation procedures
in section 2.4.
2. If an error is detected on the hard disk test, perform the HDD
problem isolation procedures in section 2.6.
3. If an error is detected on the keyboard test, perform the keyboard
problem isolation procedures in section 2.7.
4. If an error is detected on the floppy disk test, perform the FDD
