Summary of Operation

lxbios is a utility for reading/writing LinuxBIOS parameters and displaying information from the LinuxBIOS table. It is intended for x86-based systems (both 32-bit and 64-bit) that use LinuxBIOS.

The LinuxBIOS table resides in low physical memory, and may be accessed through the /dev/mem interface. It is created at boot time by LinuxBIOS, and contains various system information such as the type of mainboard in use. It specifies locations in the CMOS (nonvolatile RAM) where the LinuxBIOS parameters are stored.

For information about LinuxBIOS, see http://www.linuxbios.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.
