12 | If you have a TPM security chip in your system, which | |
13 | implements the Trusted Computing Group's specification, | |
14 | say Yes and it will be accessible from within Linux. For | |
15 | more information see <http://www.trustedcomputinggroup.org>. | |
16 | An implementation of the Trusted Software Stack (TSS), the | |
17 | userspace enablement piece of the specification, can be | |
18 | obtained at: <http://sourceforge.net/projects/trousers>. To | |
19 | compile this driver as a module, choose M here; the module | |
20 | will be called tpm. If unsure, say N. | |

21 | Notes: |
22 | 1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI | |
ec4a162a | 23 | and CONFIG_PNPACPI. |
7f2ab000 RA |
24 | 2) Without ACPI enabled, the BIOS event log won't be accessible, |
25 | which is required to validate the PCR 0-7 values. | |
