                   - Start up or restart your LS20.

                   - The system will boot from the diskette and present
                     a window which allows you the option to flash various
                     options.  Choose "2 - Update Diagnostic".

                   - The system will prompt you to enter the diskette
                     containing BKydiag.us1 and hit enter.  Insert the
                     "LS20 Diagnostics Flash Update Diskette 1 of 2" into
                     drive A and hit enter.

                   - After loading the image from the first diskette, the
                     system will prompt you to insert the diskette
                     containing diagnostics file $BKydiag.us2.  Insert the
                     "LS20 Diagnostics Flash Update Diskette
                     2 of 2" into drive A and hit enter.

                   - After the second image is loaded from diskette the system
                     will ask you to wait while the images are flashed into
                     ROM.  When this is complete you will be prompted to
