chipsec.modules.spr.rtclock_fhf module

Warning

This is a temporary module to replace the common.rtclock module for FHF platform until the 600S Series PCH is released.

Checks for RTC memory locks.

Since we do not know what RTC memory will be used for on a specific platform, returns a WARNING (rather than FAILED) if the memory is not locked.

Returns WARNING because “protected” bytes in CMOS memory are not write/read protected. This may be an issue in case firmware stores sensitive data in these CMOS locations. If nothing sensitive is stored in CMOS then you can ignore this warning.

usage:

chipsec_main -m common.rtclock [-a modify]

  • -a modify : Attempt to write to CMOS to determine write protection

Where:

  • []: optional line

Examples:
>>> chipsec_main.py -m common.rtclock
>>> chipsec_main.py -m common.rtclock -a modify

Note

This module will only run on the following platforms:

  • FHF system

  • PCH 600S series PCH
