 * 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 the following network controllers:
 *            - SMC/WD 8003E (ISA 8-bit);
 *            - SMC/WD 8013EBT (ISA 16-bit);
 *            - SMC/WD 8013EP/A (MCA).
