change into real mode
Posted: Wed Apr 10, 2002 11:00 pm
Hello,
I have some questions here on loading a kernel from a disk, in PMODE.
1.I want to change into REAL mode so as to use BIOS interrupts and then
change into PMODE again. But I dont know how to exchange data between
the two modes.
2. Is it possible if I only use NASM and DJGPP? I dont want to use GRUB
and binutils. I just want to write it myself.
3.which method is easy, changing into Real mode or VMM(virtual machine mode)?
thanks in advance.
