	AX = B101h
	EDI = 00000000h
Return: AH = 00h if installed
	    CF clear
	    EDX = 20494350h (' ICP')
	    EDI = physical address of protected-mode entry point (see <a href=../../it/31/7.html>#00731</a>)
	    AL = PCI hardware characteristics (see <a href=../../it/30/7.html>#00730</a>)
	    BH = PCI interface level major version (BCD)
	    BL = PCI interface level minor version (BCD)
	    CL = number of last PCI bus in system
	EAX, EBX, ECX, and EDX may be modified
	all other flags (except IF) may be modified
Notes:	this function may require up to 1024 byte of stack; it will not enable
	  interrupts if they were disabled before making the call
	some BIOSes do not change EDI, so applications looking for the
	  protected-mode entry point should set EDI to 00000000h before
	  calling this function
