Adding the Device Driver to System Memory
You must load the driver into system memory. For the AM-212-20 diskette drivers you must also specify
the diskette format and density on the
cause the driver to use the default values for a high density (1.44MB) native AM-SCSI format diskette.
The
SYSTEM
command line has the following format for the AM-212-20 diskette drivers:
SYSTEM driver/N /F:format /D:density cache-size flush-time
format can be:
AMOS
DOS
SCSI
density can be:
720
1.44
cache-size
flush-time
Only the first character of the switch value shown above is required. However, using the full switch name
makes the command line more understandable. Spaces are not allowed within the switch strings.
Add
SYSTEM
statements similar to these before the final system command:
SYSTEM FLH.DVR[1,6]/N /F:SCSI /D:1.44 200K 1
;
;load AM-SCSI high density driver and initialize write
;cache with a 200KB buffer and a 1 second maximum
;time between buffer flushes
SYSTEM FLD.DVR[1,6]/N /F:SCSI /D:720
;
;load AM-SCSI double density driver without write cache
