How to Read the BIOS Identification String on Intel® Server Boards and Systems

The BIOS Identification String is used to uniquely the revision of the BIOS being used on ther server. The string is formatted as follows:

BoardFamilyID.OEMID.MajorRev.MinorRev.BuildID.BuildDateTime

Where :

  • BoardFamilyID = String name for the board family (E.g. S5000PSL, S5000PAL)
  • OEMID = 3 character OEM ID. "86B" is used for Intel servers
  • MajorRev = 2 decimal digits
  • MinorRev = 2 decimal digits
  • BuildID = 4 decimal digits
  • BuildDateTime = Build date & time in MMDDYYYYHHMM format
    • MM = Two digit month
    • DD = Two digit day of month
    • YYYY = Four digit year
    • HH = Two digit hour using 24 hour clock
    • MM = two digit minute

For example, the following BIOS ID string is displayed during POST for BIOS build 3 for the S5000PSL that is generated on December 1, 2008 at 12:00 AM. The string would show as :

S5000PSL.86B.01.00.0003.120120081200



This applies to:

Intel® Server Board S5000PAL
Intel® Server Board S5000PSL
Intel® Server Board S5000VSA
Intel® Server Board S5000XSL
Intel® Server System SC5400RA
Intel® Server System SR2520SA
