Summary of Operation
|
|
--------------------
|
|
nvramtool is a utility for reading/writing coreboot parameters and
|
|
displaying information from the coreboot table. It is intended for x86-based
|
|
systems (both 32-bit and 64-bit) that use coreboot.
|
|
|
|
The coreboot table resides in low physical memory, and may be accessed
|
|
through the /dev/mem interface. 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 CMOS (nonvolatile RAM) where the coreboot
|
|
parameters are stored.
|
|

Ideas for Future Improvements
|
|
-----------------------------
|
|
1. Move the core functionality of this program into a shared library.
|
|
2. Consider adding options for displaying other BIOS-provided information
|
|
such as the MP table, ACPI table, PCI IRQ routing table, etc.
