U30, 60 – IBM 63G9811 (MCA bus interface, used on Lanstreamer MC32, Auto LS MC32 and 8229 LAN bridge TR interface card)

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.

   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". 

      The  Dual LANStreamer MC 32 adapter has two ports with a supported data rate of 4 Mbps or 16 Mbps. You  could use UTP on one port and STP on the other, likewise the data rates do not have to be the same for both ports. The Dual LANStreamer requires a 386 or better. 
 NOTE: To do RIPL, you must use adapter's port A.

Slot 8 Incompatability in 8595 and  9595 
A 00017100 (171) error occurs on POST (Power-On System Test). This problem may occur on 8595/9595 models xLx or xHx systems during the installation of any of the following adapters in micro channel slot 8: 
- IBM LANStreamer MC 32 / 16 
- IBM EtherStreamer MC 32 
- IBM Auto / Dual LANStreamer MC 32 
- IBM Dual EtherStreamer MC 32 
Fix (Pretty wild, eh?) 
Do not install any of the affected adapters in slot 8. Relocate any of the affected adapters to one of the other microchannel slots.

Adapter Data Rate
   This Token Ring Network Adapter can operate at two different data rates: 4 Mbps or 16 Mbps.  The choices are Autosense, in which the adapter determines the data rate, 16 Mbps data rate, and 4 Mbps data rate. (Ed. I recommend setting to 16Mbps if network supports it. Autosense may not correctly set ringspeed)
    < "Autosense">, 16 Mbps, 4 Mbps

Interrupt Level
   Select the interrupt level that the adapter will use to interrupt the system unit.  The preferred interrupt level is 3, but the adapter can operate on any of the four levels if necessary.  NOTE...If multiple Auto LANStreamer adapters are present in the system, they must all be set to the same interrupt level.
    <"Interrupt  3">, 2, 10, 11

Adapter I/O Address Range
   This allows you to select the micro channel I/O address range of the adapter.  This adapter utilizes two 256 byte regions on 1024 byte boundaries. For micro channel I/O cycles, this Token Ring Network adapter is selected when the micro channel I/O address is within its respective 256 byte region. If more than one adapter is used in your computer, each adapter must be assigned separate I/O address ranges.
    <"1C00-1CFF & 2000-20FF">, "2000-20FF & 2400-24FF" and many more...

Remote Program Load Address Range
   This Token Ring Network adapter Remote Program Load (RPL) memory space is relocatable within Micro Channel memory space. The adapter memory space may be located on any 16K boundary from hex 000C 0000 to 000D C000.
    <"Disabled">, "C0000-C3FFF", "C4000-C7FFF", "C8000-CBFFF", "CC000-CFFFF", "D0000-D3FFF", "D4000-D7FFF", "D8000-DBFFF", "DC000-DFFFF"

Streaming Data Select
   This Token Ring Network Adapter can operate with or without Data Streaming.  For best performance, select <Enabled>.
    <"Enabled ">, "Disabled" 

   Bus Arbitration Fairness controls whether the adapter will share the bus equitably with other devices or retain control of the bus as needed.  Under normal circumstances, select <ON>.
    <"Fairness ON ">, "Fairness OFF"

Arbitration Level
   This Token Ring Network adapter utilizes 2 arbitration levels. If more than one adapter is used in your computer,  each adapter must be assigned separate arbitration levels.
    <"Level 8 & 9">, and more...

Parity Enable/Monitor Feedback
   This Token Ring Network adapter provides the capability of generating and checking data and address parity.  In addition, this adapter also provides the capability of monitoring slave device's Selected Feedback Return Exception signals during DMA operations.
    <"Parity OFF/Monitor OFF">, "Parity ON /Monitor OFF", "Parity OFF/Monitor ON ", "Parity ON /Monitor ON "
