This procedure is a brief description of the software installation process.
For a complete description reference the Installation and Configuration Guide.

This procedure assumes that you have already installed the adapter in the
computer.

The following procedure pertains to both versions 3.51 and 4.0 of Windows NT
and each step contains the necessary notation.

	DataFire PRIme Device Driver software into a 3.5-inch floppy drive.

2.      NT 3.51 - Click the Control Panel icon in the Program Manager to open the
			  Control Panel window.
	NT 4.0 - Select Start/Settings/Control Panel to open the Control Panel 
			 window.

3.      Within the Control Panel window, double-click the Network icon:

	NT 3.51 - and the Network Settings dialog box appears.

	drive and when finished displays the DataFire PRIme Setup Wizard.

	is selected. Select any desired additional incoming transfer capabilities,

4) Software Revision History
   =========================

1/12/98   Version 1.4.0
	- Problem Report #'s:  5120,5294,5180,5184,5189,5186,5191,5192,5193,5219,5017,5187

	- Changes were made to read the correct values out of the registry and send them to the switch.

	- Grayed out some of the timmers so the user can't select or adjust them.

	- Made changes to the driver to use RRAS. 
	- Made changes to the driver so the PPP negotiation timing was correct.
	- The Verifying User Name and Password succeeds and allows RAS or RRAS to connect.

	- Made changes to the driver so when we upgrade from RAS to RRAS our ports are still available for Dial-In or Dial-Out without
	  reinstalling our drivers.

	- Made changes to the driver to fix a problem we had with French National switch types. There is a new Switch Type in the pick
	  list labeled French National (No CRC4). This is for the old French National line type.

5/19/97   Version 1.3.0
	- Changed to make compatible with Digi Wanlinks Frame Relay and X.25
	  packages.

	  channels are in use
	  Corrected several help menu items for use with the config UI.

	  function in E1 mode.

3/17/97   Version 1.2.1
	- Corrected bug in oemsetup.inf to detect compressed version of digipri.dll.
	- Used later revision digipri.dll with changes to correct transfer-in-caps bug.  This also
	  includes bugs that were later corrected in the CSU/DSU page concerning short
	  haul/long haul and its associated parameter (length/attenution).  Also fixed
	  E1 CSU/DSU defaults to include CEPT/HDB3 and inhibited B8ZS in E1 mode.
