Caution! This card's ID is shared
with the Intel TokenExpress and Pure Data MC 16/4 TR adapters! Be sure
you get the right ADF. Using an improper ADF has the potential to cause
hardware damage or misconfiguration. (WRW)

It's based on a Texas Instruments chipset, like the Madge Smart Ringnode.
Here are files relevant to the adapter...got 'em while I could...before
the darkness falls, as I'm sure it will. Already Olicom's own support section
appears to have gone dark...fortunately, their FTP server was still running.
Important: Three versions of the
OC-3129 exist. 08A4 (also a duplicate
ID!) with leaded components supports only shielded twisted pair cable (DE9
plug). 08A5 is SMT based and supports
both STP and UTP. 08A6 is SMT
based and supports STP only.
ADF Sections
(08A4, 08A5 and 08A6 are all similar)
AdapterID 0A85h "Olicom Token-Ring
MCA 16/4 Adapter (OC-3129)"
I/O Address Location
Up to four Token-Ring Network adapters may be installed
in this computer. An adapter can use one of four I/O port address
combinations. Each combination consists of two address ranges.
<Choice "0 =
0A20-0A23 & 0A30-0A3F>, 1 = 0A24-0A27 & 0A40-0A4F,
2 = 0A50-0A53 & 0A60-0A6F, 3 = 0A54-0A57 & 0A70-0A7F
Adapter Data Rate
This adapter can operate at 4 Mbps or 16 Mbps. You
MUST set the adapter data rate to the same rate as the Token-Ring Network
LAN segment to which you are connecting the adapter.
<"4 Mbps">,
16 Mbps
RPL Address location
There are 12 possible 8K blocks of PC memory
that can be assigned for accessing the RPL area of the Token-Ring Network
adapter. The preferred RPL address for the adapter is: CC000-CDFFF.
The RPL address must not be assigned for use by any other adapter or option.
<"RPL Disabled>,
CC000-CDFFF, CE000-CFFFF, D0000-D1FFF, D2000-D3FFF, D4000-D5FFF, D6000-D7FFF,
D8000-D9FFF, DA000-DBFFF, DC000-DDFFF, DE000-DFFFF, C8000-C9FFF, CA000-CBFFF
Interrupt Level
This adapter can operate on one of four interrupt levels:
2, 3, 10, or 11. The preferred interrupt level is 2, but the adapter
can operate on any of the four levels if necessary
<"Interrupt 2">,
3, 10, 11
Bus Master Arbitration Level
Bus Master Arbitration level
<"Level 8">,
9, 10, 11, 12, 13, 14
Bus Master Release Timing (absent
in 08A4)
During a Micro Channel DMA operation this Adapter
supports two different ways of releasing the bus after the Preempt signal.
After a Preempt occurs the bus can be released either immediately or after
the maximum time allotted by the Micro Channel architecture. The
best performance is achieved if this adapter is allowed to continue for
the maximum time allowed.
<"Maximum">, Immediately
Cable Type (absent
in 08A4 and 08A6 models)
STP media (Type 6) uses the 9-pin D-type connector (J3)
and UTP media (Type 3) uses the RJ45 phone-jack (J4).
<"STP media (Type 6)>,
UTP media (Type 3)
