ICH Development Kit. This is a cursory set of tests designed to provide a level of
confidence in the platform operation.
8.1 Level 1 Debug (Port80/BIOS)
Refer to the steps in Table 23 when debugging a board that does not boot.
8.2 Level 2 Debug (Power Sequence)
Table 23. Level 1 Debug (Port80/BIOS)
Step Test Pass/Fail Criteria Cause of Failure
1 Verify “SYSTEM PWRGD” LED Green
Power sequence failure – go
immediately to Level 2 debug
2 Is “PCI Reset” LED illuminated?
Decimal on Port 80 display
RED
PCI reset stuck – go to Level 3 debug
3 Verify CPURST LED is off Off
CPU reset stuck – go to Level 3
debug
4 Verify Port 80 posting
Port 80 LEDs are posting
boot codes and stopping
System Hang – Check BIOS go to
level 3 debug. Refer to AMI* BIOS
documentation for details.
5 Verify BIOS settings Latest BIOS installed
Contact Intel representative for the
latest BIOS image
6 Verify default jumper settings See default settings Improper jumper settings
