INT 1A - Intel Plug-and-Play AUTO-CONFIGURATION - GET PCI IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. ROUTING TABLE
	AX = B406h
	ES:DI -> IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. routing table header (see #01259)
Return: CF clear if successful
	    AX = 0000h
	    WORD ES:[DI] = size of returned data
	CF set on error
	    AX = error code (0059h) (see #01243)
	    WORD ES:[DI] = required size of buffer

Format of Intel Plug-and-Play AUTO-CONFIGURATION PCI IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. routing header:
Offset	Size	Description	(Table 01259)
 00h	WORD	length of IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. routing table buffer
 02h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	-> IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. routing table array buffer (see #01260)

 0Eh	BYTE	(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. v2.1+) device slot number (00h = motherboard)
