 * 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 AHA-154x series of SCSI Host Adapters
 *          made by Adaptec, Inc. These controllers were designed for
 *          the ISA bus.
