nvramtool (previously known as lxbios and cmos_util) is a utility for reading/writing coreboot parameters and displaying information from the coreboot table in CMOS/NVRAM.
The program is intended
... [More] only for x86-based Linux systems that use coreboot, but can also be used for non-coreboot systems (e.g. for dumping all NVRAM bytes). [Less]
Superiotool is a user-space utility which can
- detect which Super I/O chip is soldered onto your mainboard,
- at which configuration port it's located (usually 0x2e or 0x4e), and
- dump
... [More] all register contents of the Super I/O chip, together with the default values as per datasheet (to make comparing the values easy).
It is mainly used for coreboot development purposes (see coreboot.org for details on coreboot), but it may also be useful for other things. [Less]
coreinfo is a small informational payload for coreboot. Currently, it can display CPU information, PCI information, coreboot table information, and show an NVRAM dump.
