Analyzing the SEL
Whenever an unusual situation is reported, the SEL should be consulted:
SEL Event Example:
112 | 11/02/2009 | 09:11:14 | FW Ver Change #0x51 | 0xC1 0x09 0xFF
The sensor can be found in “Annex A” list by running a search for FW Ver Change:
Let’s analyze the “Event Data”:
Event Data 1: 0xC1
0xC1 = 1100 0001
Bit[7:6] = 11b
Bit[5:4] = 00b
Bit[3:0] = 00001b
: sensor-specific event extension code in byte 2
: unspecified byte 3
: offset from Event/Reading code (offset which triggered the event)
 01h (bit 1): Firmware or software change detected with associated Entity.
Informational. Success or failure not implied.
Event Data 2: 0x09
bit[7:0]: Version change type
 system firmware (EFI / BIOS) change
