Interrupts and FAR calls from DPMI (Developers)

posted by Laaca , Czech republic, 27.02.2012, 10:03

I want do do some experimetns with PNP BIOS and SMBIOS. These services are called by FAR Call with parameters pushed od stack. There is no problem in real mode with it but how to do it from DPMI (I want to use realmode interface)

Normally I use int 30h/AX=300h (or 301h) with values passed into register structures but now I have to first time solve how to add parameters from DPMI into realmode stack.

Can you show me some DJGPP C code for it?
(I will programm it in Freepascal but C is readable for me)
