Hi everyone,

  When I spawn a real mode program that itself
switches to protected mode and does some extended
memory access, I get a severe problem and my original
parent DJGPP program crashes.

  I've set everything back to normal including A20
line, GDT, IDT, TS flag and almost everything you can
think of. And what are the hardware interrupts DJGPP
uses for IRQ0-7. Is it INT 78-7fh ? The Task register
is modified my my program. I can't of course set this
back to what it was.

 So, what could be the problem.

And does DJGPP allow me to make reference to any
portion of the extended memory ? I don't think it
does.
Someone please help.

Thanks,
Prashant TR
