Hardware Management (Monitoring and Reporting)
General Firmware Information
Chapter 5

General Firmware Information
Firmware processing is provided by QLogic's Zircon Lite chip and an
auxiliary Winbond chip. The firmware implements industry standard
IPMI Specification 1.0 with the following extensions:
•
BIOS configuration tokens
•
Additional hardware control
•
BIOS security
KCS 1 and BT protocols are supported. Only KCS 1 is used during BIOS
POST. BT is supported at run-time (after the operating system boots).
Date/Time Initialization
The Zircon Lite's date and time is initialized after each power-on by the
BIOS. This enables accurate logging of timestamp information for events
in the SEL.
SEEPROM Organization
There are three Atmel SEEPROMs attached to the main SMBUS for
information storage. These contain the SEL, FRU, and HP NBA Tokens.
The FRU stores the product model, serial number, and other chassis and
system board information.
