2. Windows NT 3.51 Installation
2.1 If you are using Windows NT 3.51 with the XJEM3336 or
CCEM3336 Ethernet*Modem Adapters
--------------------------------------------------------------------
We highly recommend that you obtain and install Windows NT Version
3.51 Service Pack 5 before installing you adapter. There are several
fixes in SP5 which take care of several PCMCIA issues.
Installing the driver

- The Network Adapter Dialog box will appear. Click on Do Not Detect,
then click on Continue.
- From the Add Adapter Dialog box, select <Other> Requires disk from
manufacturer and click on Continue.
- Insert the Installation diskette into the floppy drive.

2.2 Obtaining and replacing PCMCIA.SYS
----------------------------------------
There is a problem with Windows NT version 3.51 if you use a
COM port other than COM3 with the USRobotics-Megahertz 336 Ethernet
Combo card XJ/EM3336. To correct this problem, you will need to
replace your PCMCIA.SYS file with a new version located on the
Microsoft FTP site.
A PCMCIA.SYS correction is now available (HOTFIX #Q152124) but is
not fully regression tested and should be applied only to systems
experiencing this specific problem. Unless you are severely impacted
by this specific problem, Microsoft recommends that you wait for the
service pack release containing this fix. Contact Microsoft Product
Support Services for more information.
The PCMCIA.SYS correction and installation instructions can be
obtained from Microsoft at the following location.
Via a web browser:
ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT351/
hotfixes-postSP4/Mhz-fix
Via an ftp utility:
Location: ftp.microsoft.com
Directory: /bussys/winnt/winnt-public/fixes/usa/NT351/hotfixes-postSP4/
Mhz-fix
Rename PCMCIA.SYS in the \WINNT35\SYSTEM32\DRIVERS directory.
Download PCMCIA.SYS from the hot fix section of the Microsoft FTP
site, and place it in the WINNT35\SYSTEM32\DRIVERS directory.
You may also download and install Service Pack 5 which includes
the above mentioned fix.

4. Troubleshooting
----------------------
You can verify which COM port your Combo card is configured for
by checking Main->Control Panel->Network. Highlight the Installed
Adapter and select Configure. Note the COM port setting.
In Windows NT 3.51, if you do not have the updated pcmcia.sys
installed, you will get 6-7 entries for Pcmcia Error 0006 in
Administrative Tools->Event Viewer. The modem and network should
still work.
Even if you don't see a server, check Administrative Tools->
NT Diagnostics->Network->Statistics. You should see bytes
received/transmitted.
All the installable ranges may not be supported by the card. Do not
install to the following IO Ports: (180, 1A0, 1C0, 1E0, 280, 2A0, 2C0, 3E0).
Note: If you have installed a Microsoft Service Pack, you will need
to re-install the service pack after the network is completely
installed. Then you will need to recopy PCMCIA.SYS to the
C:\WINNT35\SYSTEM32\DRIVERS directory.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
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.
