Can user programs or operating system write |
| Yes, operating systems and applications that | |||
data to it during normal operation? |
| conform to the TCG standard can write data to | |||
|
|
|
| the TPM during normal operation. Access to the | |
|
|
|
| NV Storage is controlled by the TPM owner. | |
|
|
| |||
Purpose? [e.g., boot code] |

How is data input to this memory? |
| Loading flash memory requires a vendor | |||
|
|
|
| ||
|
|
|
| provided firmware file and loader program | |
|
|
|
| which is executed by booting up the system | |
|
|
|
| from a floppy or OS based executable | |
|
|
|
| containing the firmware file and the loader. | |
|
|
|
| System loaded with arbitrary data in firmware | |
|
|
|
| memory would not operate. | |
