requested to insert the driver disk into the drive and specify the appropriate directory.
If you are using the original driver diskette, the files required for installation are located
in the "\WINNT" subdirectory.
If the specified drive and directory are not correct, Windows will default to
automatic installation of your SCSI hostadapter. Should Windows NT have recognized
your SCSI hostadapter and installed the appropriate driver automatically, we still
recommend using the driver contained in the host adapter package. In this case you
would have to uninstall the driver at this point by selecting the driver and clicking on
the Delete button. Restart Windows NT so that you can access the connected devices.
7.4 Summary of DC2974.SYS Command Line Switches
If you wish to use the Power Save function or if any problems are caused by
customised configurations, you can add the following switches to the SCSI driver
Start the "REGEDT32" program. Display the SCSI adapter parameters by
opening HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, and Services in
that sequence. Then choose "DC2974" and select Device. A DriverParameter entry
listing the current settings will be displayed on the right panel. Click on DriverParameter
to open a dialog that allows you to change the parameter settings.
The following parameters are supported by Windows NT:
/ID=x x = SCSI ID of the hostadapter. The SCSI-ID of the hostadapter will be set
automatically if this parameter is not specified. Valid SCSI-ID values are
0 to 7. Hostadapters supplied with a SCSI setup ignore this parameter and
use the setup settings instead.
/LUN This parameter enables the device's support of several LUNs (Logical
Units). However, most SCSI devices only have LUN 0 available to them
so that you will need this parameter only for special cases. Hostadapters
supplied with a SCSI setup ignore this parameter and use the setup
settings instead.
/*SN=.. Specifies the Target-IDs for which the synchronous/asynchronous data
transfer settings of Windows' Device Manager are to be ignored, i.e. for
which control is be given to the SCSI device. Hostadapters supplied with
a SCSI setup ignore this parameter and use the setup settings instead.
/!SN=x,..,x This parameter defines the devices that are to run in asynchronous
instead of in synchronous mode, independent of the Windows mode
