1# OpenBMC MRW Requirements
2
3This document describes the data requirements that OpenBMC has on the machine
4readable workbook XML generated by [Serverwiz2](https://www.github.com/open-power/serverwiz).
5The requirements in this document are broken up by the OpenBMC functions that
6use them.

8If a particular OpenBMC implementation doesn't use a certain function,
9then that MRW data isn't required.

11## System Inventory
12
13The system inventory can be generated from the MRW XML.  The inventory
14typically contains all FRUs (field replaceable units), along with a few
15non-FRU entities, like the BMC chip and processor cores.
16
17To specify a target in the MRW should be in the inventory:
18
19* Set the FRU\_NAME attribute of that target.

21**Note**: The BMC and cores will be automatically added without the need to
22set FRU\_NAME.
