  The 152x adapter is a PIO (Programmed I/O) 16 bit SCSI Host Adapter.  The
154x is a bus master 16 Bit host adapter.  That is the basic architecture
difference.  The 152x card is being merketed primarily as a DOS adapter.
It does have a BIOS for support of up to 2 hard disks and with the ASW-1210
ASPI driver can support up to 7 hard drives.
