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 EXA has had four standard CPUs and three optional CPUs:
— Single-Core Processor (standard on EXAs with serial numbers prior to
MY/SG/US50060000; identifies as Option N9010A-PC1 with instrument
software A.02.00 or later)
— Celeron Processor (standard on EXAs with Option 503, 507, 513, and 526
with serial numbers between MY/SG/US50060000 and
< MY/SG/US52220000; identifies as Option N9010A-PC3 with instrument
software A.04.26 or later)
— High-Performance Celeron Processor (standard on EXAs with Option 503,
507, 513, and 526 with serial numbers ≥ MY/SG/US52220000 and
< MY/SG/US55230000 and standard on EXAs with Option 532 and 544 with
serial numbers ≥ MY/SG/US51440000 and < MY/SG/US55230000;
identifies as Option N9010A-PC5; only supported on instrument software
version A.10.04 or later)
— High-Performance Dual-Core Celeron Processor (standard on all EXAs with
serial numbers ≥ MY/SG/US55230000, identifies as Option N9010A-PC7,
only supported on instrument software version A.16.05 or later)
— Dual-Core Processor (optional on EXAs; identifies as N9010A-PC2; only
supported on instrument software versions A.02.00 and later; available as
an upgrade for older EXAs)
— High-Performance Dual-Core Processor (optional on EXAs; identifies as
N9010A-PC4; only supported on instrument software versions A.10.04 or
later)
— Intel Core i7 Processor (optional on EXAs; identifies as N9010A-PC6; only
supported on instrument software versions A.16.05 or later)
Each of these CPUs used unique BIOS when they were introduced. However,
the high-performance dual-core processors and the high-performance
Celeron Processor use the same 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.
