BIOS Settings Verification
Whenever either the A4 CPU assembly or the A4BT1 CPU Battery is changed
there are certain BIOS settings that need to be verified. If these are not set
correctly the instrument may not boot up or operate correctly.
The BIOS settings that need to be verified, as well as the BIOS configuration
screens used, will vary depending on the A4 CPU assembly.
Selection of BIOS Settings Procedure
The MXA has had three standard CPUs:
— Single-Core Processor (standard on MXAs with serial numbers prior to
MY/SG/US49100000; identifies as Option N9020A-PC1 with instrument
software A.02.00 or later)
— Dual-Core Processor (standard on MXAs with serial numbers
≥ MY/SG/US49100000 to < MY/SG/US52090000; identifies as
N9020A-PC2; available as an upgrade for older MXAs)
— High-Performance Dual-Core Processor (standard on MXAs with serial
numbers ≥ MY/SG/US52090000; identifies as N9012A-PC4; available as an
upgrade for older MXAs.)
Each of these CPUs uses a unique BIOS.
The steps below will help you identify which BIOS settings procedure to
perform.
1. Connect an external USB keyboard to one of the front panel USB ports.
2. Turn on the analyzer power.
3. Confirm Agilent Technologies splash screen comes up within a few
seconds. “Agilent Technologies” will appear in white letters on a black
background.
4. Press “F2” and then “Delete” on the external keyboard when at the Agilent
Technologies splash screen to enter the CPU BIOS Setup Utility.The older
CPUs (N9020A-PC1 and N9020A-PC2) respond to “F2” while the newer
CPU (N9020A-PC4) responds to the “Delete” key.
5. If the CPU BIOS Setup Utility main screen appears as in Figure 15-3, follow
the procedure for the Single-Core Processor.
6. If the CPU BIOS Setup Utility main screen appears as in Figure 15-4, follow
the procedure for the Older Dual-Core Processor
7. If the CPU BIOS Setup Utility main screen appears as in Figure 15-5, follow
the procedure for the newer Dual-Core processor
8. If the CPU BIOS Setup Utility main screen appears as in Figure 15-6, follow
the procedure for the High-Performance Dual-Core Processor.
