HP/HPE Trusted Module Status (Type 224)

Source: dmidecode, dmioem.c, and the dumps of the data corpus.

Tells whether a trusted module (TPM or TCM) is present and enabled, and what kind of module it is. The older servers hold the status only.

Table 1. HP/HPE Trusted Module Status structure
Offset	Version	Name	Length	Value	Description
`0x00`	2.0+	Type	`BYTE`	`224`	HP/HPE Trusted Module Status indicator
`0x01`	2.0+	Length	`BYTE`	Varies	Length of the structure
`0x02`	2.0+	Handle	`WORD`	Varies
`0x04`	2.0+	Status	`BYTE`	`BITFIELD`	Bits 0-1: presence, bit 2: option ROMs are measured, bit 3: hidden
`0x05`	2.0+	Extended Status	`BYTE`	`BITFIELD`	Bits 0-1: disable reason, meaningful for a disabled module only; bits 2-5: error condition, meaningful for a module disabled for an error only
`0x06`	2.0+	Module Type	`BYTE`	`BITFIELD`	Bits 0-3: type, bit 4: standard algorithms supported, bit 5: Chinese algorithms supported
`0x07`	2.0+	Module Attributes	`BYTE`	`BITFIELD`	Bits 0-1: mounting, bits 2-3: FIPS certification
`0x08`	2.0+	Version Handle	`WORD`	`HANDLE`	Handle of the version indicator (type 216) of the firmware of the module
`0x0A`	2.0+	Chip Identifier	`WORD`	`ENUM`	The low byte tells the chip, the high byte is reserved
