Hello,

does anyone has information about BIOS reprogramming, and BIOS hardware "basics"? I want to know how does the computer maps it, loads it, or something, what regions are mapped and where.. Could anyone give me some links, search engines are full of shitty links to commercial pages.

Thanks for help.

There is no real standard.
Different BIOS vendors and even same vendor w/ different version do things like map CMOS data to different area's. As chipsets change so changes the code....

If your really interested in making your own BIOS you might want to check out http://www.linuxbios.org/

If I remeber correctly, "The Undocumented PC" (book) has some info and there is a little in Ralf Brown's int list stuff.
