bserving the Boot Routine
After you perform a visual inspection as described in the previous section, boot
the computer from a diagnostics diskette and, while the boot routine is running,
observe the computer for any indications of problems.
NOTE: To prevent possible damage to the original diagnostics diskette, always
use a backup copy of the diagnostics diskette when servicing a user's computer.
Dell recommends that users make copies of the Dell Diagnostics Diskette. For
instructions, see "Before You Start Testing" in Chapter 4 of the Dell Latitude LM Refer-
ence and Troubleshooting Guide.
To observe the boot routine, follow these steps:
1. Turn off the computer and any attached peripherals.
2. Insert a diagnostics diskette into the diskette drive. Turn on all periph-
erals and then the computer.
