Celeron Processor
There is one setting in the CPU BIOS that must be verified and may require
changing when the A4 CPU assembly or A4BT1 CPU battery is replaced. This
setting needs to be correct in order for the analyzer to always boot up
correctly.
— "IDE HDD" must be set to #1 in the "Boot priority order"
Changing and saving these BIOS settings requires a USB external keyboard.
Changes to the BIOS are fairly straightforward and should take ~30 seconds.
Verifying Boot Priority
1. Press the Right Arrow on the external keyboard five times to highlight the
Boot tab as shown in Figure 16-15.
