32-BIT DOS
Posted: Wed May 15, 2002 11:00 pm
Can some one explain how to make a 32-bit PM dos os?
By this i meen to run programs like what are made by djgpp and free pascal for dos
but with out the DPMI exstander,it dos not after run dos real mode stuff.
But need direct port accec and easy programing like dos.
It's the interrupts i can not get my head round,I know how
real mode interrupts work,But not PM one's.
Like in linux the int 0x80 how do that work compead to int 21 ?.
Thanks in advance.
