J6 is open on mine, the jumper is on one pin only.
BIOS Sticker on the board says PhoenixBIOS A486SX, G89295. The BIOS eprom is 940809.
J1 and J2 are both 20 pin headers with pin 4 missing.
U21 and U22 are solder pads only.

spread spectrum frequency-hopping radio used by the Wireless LAN Entry operates in the 2.4GHz unlicensed frequency band.
Each access point can support up to 16 active users.

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. 

Integral Antenna
   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.

The 8227 extended range model supports an external gain antenna. 

Patch 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.

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.
