Radio PC Card Configuration 2-27
MX2A137REFGD Revision A MX2 Reference Guide
Installing NDIS Drivers
The NDIS driver is the low-level protocol that runs the wireless LAN PC
card.
• If you wish to use another version of TCP/IP besides Novell
TCP/IP over ODI, use the information in this section to ensure
that the implementation will work correctly on the MX2.
• For other software implementations, you can use various
configuration files to configure a generic NDIS implementation
on the MX2.
NDIS for TCP/IP
Normally, the IP stack talks to a packet driver, which accesses the
physical hardware. Packet drivers have not been developed at this time
for the RangeLAN2 PC card. To fool the IP stack into thinking that a
packet driver is installed, a driver known as a shim can be used.
In this implementation, the NDIS driver talks directly to the RF
hardware. An NDIS–to–packet driver shim sits above the NDIS driver
and translates calls to the packet driver interface into calls that the NDIS
driver can understand. The IP stack will make calls to the packet driver
shim as if it were talking to the hardware directly. The IP stack has no
knowledge of the NDIS driver.
Using the NDIS–to–packet driver shim allows many third-party TCP/IP
implementations to work on the MX2.
Complete the following steps to install the packet driver shim:
1. Start the Configuration Utility by double-clicking on the icon in the
Configuration Utility group on your PC.
2. From the Main Menu, select the Custom button.
3. An Open dialog box will appear (see screen displays in Chapter 4).
Select the PX_PKDRV.CFG configuration file. In the next Open
dialog box, select a program settings file. (If you do not have a
specific one that you want to use, select DEFAULT.PRS.)
The following files are included automatically as part of the NDIS-
to-packet download:
DIS_PKT.DOS - NDIS-to-packet driver shim driver
PROTOCOL.2 - Sample NDIS configuration file
RL2PCM.COM
- Proxim RF ODI Driver
