Making 32-bit Dos Os
Posted: Fri May 10, 2002 12:14 pm
Can anybody tell me the best way to go about making a 32-bit dos clone.
What i mean by this is to run progs that now need DPMI
extenders.I have up to now been making a real mode dos clone and then adding a extender,but i am now thinking that this may not be the best way to do it.
This os does not have to run dos 16-bit progs,but has to run progs made with djgpp and free pascal etc for Dos.
And needs to be able to access ports and hardware etc.
It may not even be multitasking i do not know yet.
The main ? is how to do the equivalent of dos interrupts in PM ?????.
Thanks in advance.
