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:
2.
Twelve bytes are reserved for the serial number of the board in ASCII format. For
example, this field could contain:
3.
Sixteen bytes are reserved for the board ID in ASCII format. For example, for a
16 MB, 25 MHz MVME167 board, this field contains:
4.
Sixteen bytes are reserved for the printed wiring assembly (PWA) number
assigned to this board in ASCII format. This includes the
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 a 16 MB, 25 MHz
MVME167 board at revision A, the PWA field contains:
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:
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 systems serial ID, for boards 1used in a system.
