host adapter on the DECstation 5000 series, and for the PMAZ-AA and related
TURBOchannel SCSI-adapter option boards. The
asc is a
medium-performance implementation of the SCSI-I common command set supporting
synchronous and asynchronous SCSI devices. The driver provides no support for
targets with multiple Logical Unit Numbers (LUNs).
