Как распространить TSTP при запущении программы как другой пользователь

Я думаю, что вы ищете, это Flashrom . При условии, что ваша система поддерживается, вы можете прочитать контент вашего BIOS путем выдачи

# flashrom -r 

, если вы хотите только сохранить так называемый CMOS CMOS (те вне байты, которые вы сохраняете конфигурацию, например, сигнализация на RTC et Al) Ядро NVRAM водитель и устройство могут помочь вам:

config NVRAM
     tristate "/dev/nvram support"
     depends on ATARI || X86 || (ARM && RTC_DRV_CMOS) || GENERIC_NVRAM
     ---help---
       If you say Y here and create a character special file /dev/nvram
       with major number 10 and minor number 144 using mknod ("man mknod"),
       you get read and write access to the extra bytes of non-volatile
       memory in the real time clock (RTC), which is contained in every PC
       and most Ataris.  The actual number of bytes varies, depending on the
       nvram in the system, but is usually 114 (128-14 for the RTC).

       This memory is conventionally called "CMOS RAM" on PCs and "NVRAM"
       on Ataris. /dev/nvram may be used to view settings there, or to
       change them (with some utility). It could also be used to frequently
       save a few bits of very important data that may not be lost over
       power-off and for which writing to disk is too insecure. Note
       however that most NVRAM space in a PC belongs to the BIOS and you
       should NEVER idly tamper with it. See Ralf Brown's interrupt list
       for a guide to the use of CMOS bytes by your BIOS.

       On Atari machines, /dev/nvram is always configured and does not need
       to be selected.

       To compile this driver as a module, choose M here: the
       module will be called nvram.
