Single-Core Processor
There are two settings in the CPU BIOS that must be verified and may require
changing when the A4 CPU assembly or A4BT1 CPU battery is replaced. These
settings need to be correct in order for the analyzer to boot up and operate
correctly.
— "IDE 2" must be set to #1 in the "Boot priority order"
— "CK-408 Spread Spectrum" must be set to "Enabled"
Changing and saving these BIOS settings requires a USB external keyboard.
Changes to the BIOS are fairly straightforward and should take ~30 seconds.
