| 10 | If you have a TPM security chip in your system, which |
| 11 | implements the Trusted Computing Group's specification, |
| 12 | say Yes and it will be accessible from within Linux. For |
| 13 | more information see <http://www.trustedcomputinggroup.org>. |
| 14 | An implementation of the Trusted Software Stack (TSS), the |
| 15 | userspace enablement piece of the specification, can be |
| 16 | obtained at: <http://sourceforge.net/projects/trousers>. To |
| 17 | compile this driver as a module, choose M here; the module |
| 18 | will be called tpm. If unsure, say N. |
| 19 | Notes: |
| 20 | 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI |
| 21 | and CONFIG_PNPACPI. |
| 22 | 2) Without ACPI enabled, the BIOS event log won't be accessible, |
| 23 | which is required to validate the PCR 0-7 values. |

| 58 | (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it |
| 59 | will be accessible from within Linux. |
