These puppies clean up signals, making them more "square".
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.
Slot 8 Incompatibility in 8595 and 9595 (SF2223)
Failure to Obtain IP Address Via DHCP on Token Ring w/ SP2 (Q163383)
The 8-digit error codes on the display panel are 0281nnx0, where:
The first and last digit is always 0
281 is the decimal equivalent of the device ID
nn represents the type of error
x represents the slot number of the adapter in
The values for nn are:
|85||Configuration Compare failure|
|90||Adapter Card Test failure|
|91||Open Phase Test failure|
|93||Transmit/Receive Test failure|
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.
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 that support data rates 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

Adapter Data Rate
This adapter can operate at 4 Mbps or 16
Mbps. Autosense - adapter determines 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)
16 Mbps, 4 Mbps
Interrupt that the adapter uses to
interrupt the system unit. Interrupt level 3 is preferred, but
the adapter can operate on any of the four levels if
necessary. Note: If multiple
Auto LANStreamer adapters are in the same system, they must
all use the same interrupt level.

Adapter I/O Address Range
range of the adapter. It uses two 256 byte regions
on 1024 byte boundaries. For micro channel I/O cycles,
this 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.

Remote Program Load Address Range
The adapter's Remote Program Load (RPL)
memory space is relocatable within M/C memory space. The
memory space may be located on any 16K boundary from hex
000C 0000 to 000D C000.

Streaming Data Select
The Adapter can work with / wo Data
Streaming. For best performance, select
<"Enabled ">, "Disabled"
Bus Arbitration Fairness controls whether
the adapter shares the bus equitably with other devices
or retains control of the
bus as needed. Under normal circumstances, select
<"Fairness ON ">,
This adapter uses 2 arbitration
levels. If more than one adapter is used in your
computer, each adapter
must be assigned separate arbitration levels.

Parity Enable/Monitor Feedback
This adapter can generate and check data
and address parity. It can also monitor slave device's
Selected Feedback Return Exception signals during DMA operations.
