There are a lot of parts on this adapter. It has a fairly high component density.

Unlike the Auto Lanstreamer MC32, Lanstreamer MC32 and the 8229 bridge TR interface card, there are no status LEDs of any sort on this adapter card.

If you use Windows NT 4.0 (workstation or server) with this adapter, you must use Service Pack 3 or higher. Microsoft decided they should count MCA slots differently than IBM did. As a result, IBM Streamer family adapters don't work out of the box on a fresh NT install. You will get "a device attached to the system is not functioning" messages in the system event log and the adapter will not come up.

I don't know if my adapter is halfway broken or not, but thus far only port B on mine works. I am presently investigating this issue to see if it can be resolved.

Microcode Update Warning: The Ardent Tools page about the Dual LANStreamer says: Do not flash the MCA DLS in a 520. Pull the MCA DLS from system and flash in seperate system. Flashing in the 520 CAN PERMANENTLY DAMAGE the microcode on the DLS.

If you do elect to update the microcode on your adapter, it may be a good idea to run your computer on backup power during the flashing process. I would also suggest cycling power to the system before you do the flash to be sure you are "starting fresh".
