Hi netters,

	I am trying to setup an interrupt descriptor table in 80386 protected 
mode, based on the program supplied by Tom Green, DDJ sept 89.  I have set up
the actual table and everything seems to be in places ( I have used T Debugger
to check various address) and the program runs ok before I load the idtr.  
However, once I loaded the base address of the IDT to idtr, even before I turn
on the interrupt, the program hangs.  I think the problem is : when I call the routine real_mode(), which is a function to set me back to real mode, somehow the stack got mixed up and would not return properly.  But I did not know why, and I thought loading idtr would not affect anything else, am I right?

	Is anyone out there doing similar things?  I would like to hear from you.  Thanks for reading this.
