Пакет nvramtool: Информация

nvramtool is a utility for reading/writing coreboot parameters
and displaying information from the coreboot table.

At boot time, coreboot places a table (known as the coreboot
table) in low physical memory.  The contents of this table are
preserved even after coreboot transfers control to the kernel and
the kernel initializes itself.  The coreboot table contains
various system information such as the type of mainboard in use.
It also specifies locations in the CMOS (nonvolatile RAM) where
the coreboot parameters are stored.
