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. + +For information about coreboot, see http://www.coreboot.org/. + +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. |
