DESCRIPTION
This driver provides access to SCSI devices connected to NCR-5380/NCR-53C400 SCSI adapter.

It's possible to use the adapter without IRQ line. The data rate then slightly decreases (by 20-30%).

The flags keyword in the configuration file can be used to set some adapter driver parameters:
