9	---help---
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.
