How to access the BIOS in Linux using C


Hi,
I am trying to make a utility that gathers system information. I need to access the information stored in the BIOS such as RAM size, Processor speed, etc. Please let me know how to access these using a C program.

Thanks
Shivanu

You can read information about the processor by parsing the file /proc/cpuinfo; this is not stored in the BIOS as far as I know. Neither is RAM size, which you can get through /proc/meminfo.
There's probably also an API call for this somewhere.
The BIOS information itself can be accessed through /dev/nvram.
