IBM Wireless LAN (Advanced) and Wireless LAN Entry files that work for
me. My working 8227 DOS RPL Boot Diskette image is the SAMPBOOT.DSK image.
This is used when creating the OS/2 DOS Client RPL Image.

support up to 16 active users.
Wireless LAN Entry 8227 card
The 8227 card is functionally identical to the IBM Wireless LAN Entry
Adapter that the clients use, except that it has additional flash memory
on it. The 8227 card comes preloaded with operational software loaded on
the flash memory. When the 8227 is switched on, it verifies that the card
is in Local Program Load (LPL) mode and loads the code from the card.
The 8227 can load its operational software and configuration information
in one of two ways - local program load or remote program load.
The integral antenna is built in to the transceiver which
in turn is part of the PCMCIA Wireless adapter and is the only one which
can be used in a workstation. It transmits over a 360° area with equal
signal strength in all directions. In many environments this antenna will
be used in both the
workstations and the 8227s. An 8227, so equipped, should be mounted
high up. Install it against a ceiling, for example, as close to the center
of the required operating area as possible. The workstations in the cell
can be arranged anywhere within the area of coverage. This antenna should
only be used in the horizontal plane.
Wireless LAN Entry 8227 XR card
The 8227 extended range model supports an external gain antenna.
The patch antenna is an alternative to the integral antenna
for the 8227. It
connects to the PCMCIA Wireless adapter by cable, so it may be installed
some distance from the 8227 itself. The range of transmission is asymmetrical,
forming two lobes of 180° each. One lobe takes the shape of a pointed
dome and has a range somewhat greater than the integral antenna. The other
lobe is a flattened dome and covers a much smaller area. This antenna is
typically mounted high up against a wall and oriented such that the largest
lobe points in the direction of the largest workstation concentration.
Local Program Load (LPL) -- This
is the default loading mode. The operational software and configuration
information for the 8227 are contained on the 8227 card you received as
part of the kit. In LPL mode, the 8227 loads its operational software and
configuration information directly from the 8227 card installed in its
adapter slot. Chapter 3 describes the procedures you will need to follow
to perform an LPL installation of the 8227 card.
Remote Program Load (RPL) -- If
you change the loading mode to RPL, the operational software and configuration
information are automatically obtained by the 8227 from a file server on
the local Ethernet segment (see Figure 2-1 in topic 2.0). The software
and configuration files on the
8227 card are ignored. Chapter 4 describes the procedures that you
will need to follow to perform an RPL installation of the 8227 card.

8227 Card Removal
1. Make sure the 8227 is off.
2. If the external patch antenna is being used, disconnect the
antenna cable from the adapter cable.
3.Push the adapter ejector button.
4.Pull the adapter out of the adapter slot.
5.Put the plastic adapter-slot cover over the adapter slot.
