 * 86Box	A hypervisor and IBM PC system emulator that specializes in
 *		running old operating systems and software designed for IBM
 *		PC systems and compatibles from 1981 through fairly recent
 *		system designs based on the PCI bus.
 *
 *		This file is part of the 86Box distribution.
 *
 *		Implementation of Slot 2 machines.
 *
 *		Slot 2 is quite a rare type of Slot. Used mostly by Pentium II & III Xeons
 *		These boards were also capable to take Slot 1 CPU's using Slot 2 to 1 adapters.
