A4 Processor Board Assembly Troubleshooting
BIOS Settings
As with other types of PC processor board assemblies the A4 Processor board
assembly has a number of settings particular to the hardware on the board.
These settings are saved in a separate memory location on the board and
accessed by the BIOS (Basic Input Output System) Setup Utility. If these
settings are changed from those that the instrument was initially shipped with
this could cause a problem with the booting and/or functionality of the
instrument.
If the instrument is having a problem booting up, but is functional enough to
enter the BIOS Setup Utility you will want to verify that the BIOS settings have
not been changed. The instrument was originally shipped with the settings
shown in Figure 9-2 through Figure 9-20.
Accessing BIOS Setup Utility
(serial numbers <MY/SG/US51360000)
To successfully navigate the BIOS Setup Utility you will need to have an
external USB keyboard connected to the instrument. Then, when the initial
Keysight Technologies splash screen is displayed at power-up, press F2 on the
keyboard. Once this is pressed you should see a display like that of Figure 9-2,
the main BIOS Setup Utility screen.
If you select to use the “Load Setup Defaults” function found on the BIOS Exit
menu (Figure 9-20) you will then need to reset the following settings. They are:
— “IDE 2:” under “Boot priority order:” to position “1” (Figure 9-19)
