COMMENTS ="
 The INF-760 is an  Intelligent SCSI  Host Adapter for the EISA bus
systems. It supports SCSI-2 protocol on the SCSI bus and uses EISA bus
master protocol for the data transfer.\n\n
On the INF-760 upto 16MByte of disk data cache is supported, providing
multi-fold performance improvement.\n\n"
