Record ID
(RID) ID used for SEL Record access.

Timestamp
(TS) Time when event was logged. LS byte first.
Example: TS:[29][76][68][4C] = 4C687629h = 1281914409 =Sun, 15 Aug 2010
23:20:09 UTC
Note: There are various websites that will convert the raw number to a date/time.

Manufacturer ID LS Byte first. The manufacturer ID is a 20-bit value that is derived from the IANA
‘Private Enterprise’ ID.
Most significant four bits = reserved (0000b).
000000h = unspecified. 0FFFFFh = reserved.
This value is binary encoded.
For example the ID for the IPMI forum is 7154 decimal, which is 1BF2h, which would
be stored in this record as F2h, 1Bh, 00h for bytes 8 through 10, respectively.
