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. 7 8If a particular OpenBMC implementation doesn't use a certain function, 9then that MRW data isn't required. 10 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. 20 21**Note**: The BMC and cores will be automatically added without the need to 22set FRU\_NAME. 23
