My computer's ROM setup routine is located at 0f000h:0100h.  There's a jump
from there to the actual code (jumps past the data), which leads me to
speculate that this address may be standard (I mean, it's such a nice *round*
number).  Anyone know where the setup program is in their computers?  Anyway,
I don't have the setup utility for mine, so I wrote this little program:

	cseg	segment	para public 'code'
		assume	cs:cseg
		org	100h		; make it a .COM program
	begin:	jmp	start
	setup	label	dword		; the ROM BIOS CMOS setup
		dw	0100h,0f000h
	start	call	setup		; call the setup,
		mov	ax, 4c00h	; then terminate, errorlevel==0
		int	21h
	cseg	ends
		end	begin

My setup utility gives me the option of either returning to DOS, which will
return control to this program (at which point the program terminates and
the user is returned to the DOS prompt), or rebooting.
 
Warning: if there is no setup utility at 0f000:0100h then this program will
have unpredictable results, probably causing the computer to 'hang'.  The
author's computer is an Autocomputer VIP Model: AUVA 220 (IBM PC-AT
compatible).  Your mileage may vary.
