Follow the steps listed below to ensure the best and proper
installation of the V.90 upgrade. Place a copy of the unzipped
contents of the V90_516i.ZIP file onto a floppy disk to create
an installation diskette.
********************************************************************
********************* 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

**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.
Download Driver Pack

Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
