* 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.

According to the manual it has to do with the NMI which
