I/O Port 4D1h			Interrupt Edge/Level Select Register 2 (R/W)	Reset Value: 00h
Notes: 1. If ICW1 - bit 3 in the PIC is set as level, it overrides the setting for bits 7:6 and 4:1 in this register.
	2. Bits [7:6] and [4:1] in this register are used to configure a PCI interrupt mapped to IRQ[x] on the PIC as level-sensitive
		(shared).

7		IRQ15 Edge or Level Sensitive Select. Selects PIC IRQ15 sensitivity configuration.
		0: Edge.
		1:	Level.

6		IRQ14 Edge or Level Sensitive Select. Selects PIC IRQ14 sensitivity configuration.
		0: Edge.
