It is posible to use my real mode interrupts in Pmode, or it?s necesary to create other?
The bios interrup it?s accesible in Pmode?

You have two options: either write a V86-mode monitor in your kernel, and execute BIOS interrupts inside there, or re-implement the functionality you need from the BIOS. It is usually considered easier (and better, from a performance point of view) to re-write the BIOS services inside your OS.

Tim Robinson:
How is V86-Mode monitor? ???
In the case to reimplement the functionality of a BIOS, I want to create same interrupts?
Thanks

Try to get hold of the source code,for a DPMI exstender like cwsdpmi or go32-v2,as these use both methods
