Accessing BIOS memory from user space

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi All,

My board is having 8MB of memory of which 2 MB is for the BIOS. I am loading Linux at 2 MB but at initialisation time I give all 8MB for Linux. Linux marks the 1st 2MB as non-usable and makes use of the rest of the 6MB.

I have a requirement to access the 1st 2MB directly from the user space. Can anyone give me ideas as to how to do this?

Is /dev/kmem a possible candidate? I am not sure how kmem behaves for BIOS memory.

Thanks in advance
Raghav
