The fields are defined as follows:
1. Four bytes are reserved for the revision or version of this structure. This
revision is stored in ASCII format, with the first two bytes being the major
version numbers and the last two bytes being the minor version numbers.
For example, if the version of this structure is 1.0, this field contains:
0100
2. Twelve bytes are reserved for the serial number of the board in ASCII
format. For example, this field could contain:
000000470476
3. Sixteen bytes are reserved for the board ID in ASCII format. For example,
for an MVME162 board with MC68040, SCSI, Ethernet, 4MB DRAM, and
512KB SRAM, this field contains:
MVME162-23 (The 10 characters are followed by six blanks.)
4. Sixteen bytes are reserved for the printed wiring assembly (PWA) number
assigned to this board in ASCII format. This includes the 01-W prefix. This
is for the main logic board if more than one board is required for a set.
Additional boards in a set are defined by a structure for that set. For
example, for an MVME162 board with MC68040, SCSI, Ethernet, 4MB
DRAM, and 512KB SRAM, at revision A, the PWA field contains:
01-W3814B01A (The 12 characters are followed by four blanks.)
5. Four bytes contain the speed of the board in MHz. The first two bytes are
the whole number of MHz and the second two bytes are fractions of MHz.
For example, for a 25.00 MHz board, this field contains:
2500
6. Six bytes are reserved for the Ethernet address. The address is stored in
hexadecimal format. (Refer to the detailed description in Chapter 4.) If the
board does not support Ethernet, this field is filled with zeros.
7. These two bytes are reserved.
8. Two bytes are reserved for the local SCSI ID. The SCSI ID is stored in
ASCII format.
9. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the memory mezzanine board in ASCII format. This does not
include the 01-W prefix. For example, for a 4MB parity mezzanine at
revision A, the PWB field contains:
3837B02A
10. Eight bytes are reserved for the serial number assigned to the memory
mezzanine board in ASCII format.

11. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the serial port 2 personality board in ASCII format.
12. Eight bytes are reserved for the serial number assigned to the serial port 2
personality board in ASCII format.
13. Eight bytes are reserved for the board identifier, in ASCII format, assigned
to the optional first IndustryPack a.
14. Eight bytes are reserved for the serial number, in ASCII format, assigned
to the optional first IndustryPack a.
15. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the optional first IndustryPack a.
16. Eight bytes are reserved for the board identifier, in ASCII format, assigned
to the optional second IndustryPack b.
17. Eight bytes are reserved for the serial number, in ASCII format, assigned
to the optional second IndustryPack b.
18. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the optional second IndustryPack b.
19. Eight bytes are reserved for the board identifier, in ASCII format, assigned
to the optional third IndustryPack c.
20. Eight bytes are reserved for the serial number, in ASCII format, assigned
to the optional third IndustryPack c.
21. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the optional third IndustryPack c.
22. Eight bytes are reserved for the board identifier, in ASCII format, assigned
to the optional fourth IndustryPack d.
23. Eight bytes are reserved for the serial number, in ASCII format, assigned
to the optional fourth IndustryPack d.
24. Eight bytes are reserved for the printed wiring board (PWB) number
assigned to the optional fourth IndustryPack d.
25. Growth space (65 bytes) is reserved. This pads the structure to an even 256
bytes.
26. The final one byte of the area is reserved for a checksum (as defined in the
MVME162Bug Debugging Package User’s Manual) for security and data
integrity of the configuration area of the NVRAM. This data is stored in
hexadecimal format.
