Board Area Format Version

The following table describes the board area format version field.

Table: Board Area Format Version

Bits	Meaning
7:4	Reserved
3:0	Format version number, 0001b for IPMI FRU Spec. The value for this field is 0x01.

Board Information Area Length

Note: This field is denoted in multiples of 8.

The elements of the board information area are padded up to the nearest 8-byte boundary (using absolute offsets). The default pad value is 0x0. The total length of the board information area is in 8-byte units.

Example Content: 0Eh x 8 byte = 64 bytes

Language Code

Default value 00h indicates that the language code is English and all fields encoded as an 11b type are specified in single-byte ASCII format.

Note: For a detailed list of available language codes, refer to the IPMI FRU Specification

Example Content: 0x00 indicates English

Manufacturing Date and Time

This value specifies the date and time that the board was manufactured. This field value is the numeric value that is calculated as the number of minutes from 0:00 hours on 1 January 1996 (1/1/96), and stored as the least-significant byte first (i.e., in offset 03h). If the field is not specified, the default value is 000000h.

Note: There are 525950 minutes in a non-leap year or 527040 minutes in a leap year. This algorithm times out in the year 2028.

Manufacturer Name

The value for this field is Xilinx encoded in 8-bit ACSII + Latin 1. The values for this field are 0x58, 0x49, 0x4C, 0x49, 0x4E, and 0x58.

Manufacturer Type/Length Byte

This value defines the type and length of the board manufacturer field. See Appendix A for information on the IPMI defined type/length byte format. The fixed value for this field is 0xC6, which is decoded as 8-bit ASCII + Latin , and 6 bytes long.

Product Name

The ASCII character value consists of the variable-length product name (maximum length is 16 bytes). The product name is programmed at the time of manufacturing. This value is static for a given board. If the value is less than the chosen board product name length, the remaining/ trailing bytes will occupy empty spaces.

Product Name Type/Length Byte

This value defines the type and length of the product name field. See Appendix A for information on the IPMI defined type/length byte format. The fixed value for this field is 0xD0, which is decoded as 8-bit ASCII + Latin 1, and 16 bytes long.

Board Serial Number

The ASCII character value consists of the variable-length serial number (maximum length is 14 bytes). The serial number is programmed at the time of manufacturing. This value is static for a given board. If the value is less than the chosen board serial number length, the remaining/ trailing bytes will occupy empty spaces.

Board Serial Number Type/Length Byte

This value defines the type and length of the board serial number field. See Appendix A for information on the IPMI defined type/length byte format. The fixed value for this field is 0xCE, which is decoded as 8-bit ASCII + Latin 1, and 14 bytes long.

Part Number

The ASCII character value consists of the variable-length part number (maximum length is 9 bytes). The part number is programmed at the time of manufacturing. This value is static for a given board. If the value is less than the chosen board part number length the remaining bytes are filled with 0x00.

Part Number Type/Length Byte

This value defines the type and length of the part number field. See Appendix A for information on the IPMI defined type/length byte format. The fixed value for this field is 0xC9, which is decoded as 8-bit ASCII + Latin 1, and 9 bytes long.

FRU File ID

This field is used to indicate the version of the binary data used to program the FRU storage device. It is intended to aid with FRU file data identification and its use is optional. Non-00h and non-FFh content indicates that this field is being used for FRU file version identification.

0x00: This field is unused for version identification
0x01: Version 1 of FRU data
0x02: Version 2 of FRU data
0xnn: Version nn of FRU data
0xFF: This field is used for version identification

The Xilinx fixed value for this field is 0x00.

FRU File ID Type/Length Byte

This value defines the type and length of the FRU file ID field. See Appendix A for information on the IPMI defined type/length byte format. The fixed value for this field is 0x01, which is decoded as binary data, and 1 byte long.

End of Fields

The value for this field is 0xC1.

Pad

Pad with 0x00 until the board information area ends on an 8-byte boundary (relative to absolute offsets).

Board Area Checksum
