What is nvramtool
nvramtool is:
nvramtool is a utility for reading/writing coreboot parameters in NVRAM/CMOS and displaying information from the so-called ‘coreboot table’.
The coreboot table resides in low physical memory. It is created at boot time by coreboot, and contains various system information such as the type of mainboard in use. It specifies locations in the NVRAM/CMOS (nonvolatile RAM) where the coreboot parameters are stored.
