INT 15 U - AMIAmerican Megatrends, Inc.(American Megatrends, Inc.) A hardware, software and firmware company founded in 1985. PCI BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. - CPU(Central Processing Unit) The microprocessor which executes programs on your computer. SPEED CONTROL
	AX = DA01h
	CL = subfunction (00h-02h)
	    00h set low CPU(Central Processing Unit) The microprocessor which executes programs on your computer. speed
	    01h set high CPU(Central Processing Unit) The microprocessor which executes programs on your computer. speed
	    02h get current CPU(Central Processing Unit) The microprocessor which executes programs on your computer. speed
Return: CF clear if successful
	    AH = current/new CPU(Central Processing Unit) The microprocessor which executes programs on your computer. speed (00h low, 01h high)
	    AL = ??? (00h)
	CF set on error
	    AH = error code (86h unsupported subfunction)
Notes:	in the v1.00.05.AX1 BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly., subfunctions 00h and 01h are NOPs in both
	  protected and V86see Virtual-86 Mode modes due to a test of MSW bit 0
	setting the CPU(Central Processing Unit) The microprocessor which executes programs on your computer. speed also generates the same audible signals generated
	  when manually switching speeds with Ctrl-Alt-Gray- and Ctrl-Alt-Gray+
BUG:	the BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. apparently intends to return CF set if ???, but fails to use
	  a different exit path in that case, resulting in CF clear
