| 11 | This driver emulates a TPM, providing access to base functions | |
| 12 | such as reading and writing TPM private data. This is enough to | |
| 13 | support Chrome OS verified boot. Extend functionality is not | |
| 14 | implemented. | |

37 | help |
| 38 | Some broken TPMs have a limitation on the number of bytes they can | |
| 39 | receive in one message. Enable this option to allow you to set this | |
| 40 | option. The can allow a broken TPM to be used by splitting messages | |
| 41 | into separate pieces. | |
