********************************************************************
*********************   DO THIS STEP FIRST   ***********************
********************************************************************

#1	From the Win 95 "Device Manager" or "Modem Properties" 
	dialog box, you will need to "Remove" the current 
	installation of the "Rapid Transit 56K ISA Modem"
	or "56K V90 ISA Modem"

#2	Delete the file LTMODEM.INF from the C:\WINDOWS\INF\OTHER  
	directory
	
	**Note1:	Depending on which build of Win 95 you have
			installed on your system. The file may have
			been renamed LTLTMODEM.INF. 

	**Note2:	Depending on which version of Windows you 
			are running. The files may be located in one
			of the following directories:

	                 Win 95a (OSR-1)        C:\Windows\INF
	                 Win 95b (OSR-2)        C:\Windows\INF\Other
	                 Win 95c (OSR-2.5)      C:\Windows\INF\Other
	                 Win 98                 C:\Windows\INF\Other

	**Note3:	If you are running Win 95a or Win 98 on your
			system. The file may have be in the 
			C:\WINDOWS\INF directory.  The file may have
			been renamed OEMxx.INF. In which case you 
			may have to examine each file named 
			OEMxx.INF in order to determine which is the
			correct .INF file

	

#3	Delete the file LTWAVE.INF from the C:\WINDOWS\INF\OTHER 
	directory.
	
	**Note1:	Depending on which build of Win 95 you have
			installed on your system. The file may have
			been renamed LTLTWAVE.INF. 

	**Note2:	Depending on which version of Windows you 
			are running. The files may be located in one
			of the following directories:

	                 Win 95a (OSR-1)        C:\Windows\INF
	                 Win 95b (OSR-2)        C:\Windows\INF\Other
	                 Win 95c (OSR-2.5)      C:\Windows\INF\Other
	                 Win 98                 C:\Windows\INF\Other

	**Note3:	If you are running Win 95a or Win 98 on your
			system. The file may have be in the 
			C:\WINDOWS\INF directory.  The file may have
			been renamed OEMxx.INF. In which case you 
			may have to examine each file named 
			OEMxx.INF in order to determine which is the
			correct .INF file.

#4	Run the A:\PREPSYS.BAT FILE

	The PREPSYS.BAT file is a simple Batch file which will attempt
	to locate key modem driver components in the C:\Windows\System 
	directory. This is normally the default name given to the 
	directory which is created at the time Windows was first 
	installed to your system. The Batch file will then delete 
	these files from the system in preparation for the new 
	drivers. 

	**Note1:	If you have recently upgraded your version of
			Windows or have a custom installation.  The 
			directory may have a different name, such as;
			C:\Win95\System  or  similar name.  If this is
			the case you may see the message;

				  "File Not Found" 
			
			If this occurs you can perform a "Search" for 
			and delete the files listed below. This is the
			same function performed by the PREPSYS.BAT file.
			Provided the files are located in the 
			C:\Windows\System  directory.

				   LTMODEM.VXD
				   LTCOM.VXD
				   LTVCD.VXD
				   LTDSVD.DLL

			This essentially is the same function performed
			by the PREPSYS.BAT file.  Provided the files are
			located in the C:\Windows\System directory.

#5	Reboot your system, when Windows prompts for a driver disk 
	insert the newly created driver disk into the A: drive.
	
	**Note1:	If the file V90_516i.ZIP was unzipped into a
			directory on the hard drive, rather than to
			a floppy disk.  You must tell Windows what
			directory the driver files are located.

	**Note2:	If windows does not prompt for a driver disk,
			then it is possible that copies of the old
			driver files are still present on the system.
			If so, you should perform the installation 
			again from Step #1. If after performing the 
			installation, windows still does not ask for
			a driver disk. Contact Technical Support at
			(510)249-1605 for assistance.
