	I have a question involving Protected mode for 386/486 (no 286)
programming. The scenario is as follows:  The program is a normal DOS
executable that is designed to take COMPLETE control of the pc. (ie it has
no intention of returning to dos once it is running). This program sets up
a simple protected mode 32-bit operating environment solely for the purpose
of experiment with the full power of the 386/486. I have a question about
handling hardware IRQs in this environment. 
	BIOS originally sets the hardware IRQs 0 -7 to use INTs 8 - 15, and 
IRQs 8 - 15 to use INTs 70h - 77h. The IRQ 0 - 7 assignments cause confilcts 
with the reserved exception INTs (ie INT 8 is reserved by Intel for Double 
Fault exceptions, and is also set by BIOS to receive IRQ0 hardware interrupts)
	How should this be handled? Is there anything that needs handling, or
am I missing something in this picture. Do the IRQs have to be re-mapped to 
different INTs that aren't reserved by Intel (map IRQs 0-7 to INTs 32-30)?
If I do have to remap the IRQs, then how do I do so in the 386 environment.
I have seen the BIOS source for an AT that does the original IRQ to INT 
mapping, and how to accomplish this, but its written for a 286 AT and Im 
not sure if that will work on this machine. (PS/2 model 70 386). 
	Any help regarding this, or Protected mode programming in general 
would be appreciated. Unfortunately, most of the information that I have
found on Protected mode has few, if any examples. Thanks in advance...
