rewriting content of BIOS
Posted: Wed May 26, 2004 11:00 pm
Dear Sir,
Is it possible to rewrite the content of BIOS through C program. If we know the port no. shall we able to write some thing into that area.
what i need is to reduce the extended memory to 4MB through my program.
will the outportb will help to rewrite content to 4MB(or something) if so how
i know the port nos. 30h and 31h where the extended memory lies and how to read the content of that using inportb() and outport().
regards,
anil
