/***************************************************************************
Adaptec AHA-1740/44 and AHA-1740A/42A Fast SCSI host adapters
These are actually EISA cards, though they also have a compatibility
mode that provides an interface like the older ISA AHA-154X series.
The HPC microcode is copied to and then executed out of RAM, allowing
it to be reprogrammed by the host.
The AHA-1740 and AHA-1740A have different board layouts and require
different microcode, though they share the following ICs:
AIC-565 Bus Auxiliary Interface Chip
AIC-575 EISA Configuration Chip
AIC-4600 HPC (HPC46003V20)
AIC-6251A SCSI Interface and Protocol Chip
IDT7201 512x9 FIFO (2 on board)
Intel 82355 Bus Master Interface Controller
AHA-1742A is the same as AHA-1740A, only with the FDC populated.
AHA-1744 uses the same layout as AHA-1740, but populates the area
around the SCSI port with DS36F95J differential drivers.
