Intel RSD Physical Device Mapping Information (Type 200)

Source: Intel® RSD Firmware Extension Specification Software v2.3.2 (document 337201-003US), section 3.11.

Declares the relationship between physical devices and their SMBIOS representation, allowing to link structures to physical locations of the devices in the system.

Each structure describes devices of one type only. There may be several structures describing devices of the same type, if they do not fit into a single structure.

Table 1. Intel RSD Physical Device Mapping Information structure
Offset	Version	Name	Length	Value	Description
`0x00`	2.0+	Type	`BYTE`	`200`	Physical Device Mapping Information indicator
`0x01`	2.0+	Length	`BYTE`	Varies	Length of the structure
`0x02`	2.0+	Handle	`WORD`	Varies
`0x04`	2.0+	Physical Device Type	`BYTE`	`ENUM`	Type of the devices described by the structure, see Physical device types
`0x05`	2.0+	Reserved	`BYTE`	`0x00`
`0x06`	2.0+	Physical Device Mappings	Varies	Varies	Locations of the devices, 4 bytes each, see Physical device mappings
