Note from Andreas: The zip files contains my modification for
use with IBM OS/2 networking, simply copy it's content to \IBMCOM\MACS

to Andreas again for writing it!)

the 50 pin cable from the side card is attached in only one way.

The DAS side card's cables will only fit in the base card if the side
card is to the right of the base card. It was easier to put the cables
on before trying to put the adapters in the MCA slots because you can have
both cards "flat". For us with NP-MCA-3 cards that were banged about some,
check the (exposed!) pin header on the base card. Some of the pins may
have been bent some, and trying to install the cable will be frustrating.
Looks like its time to start my work on a FDDI Howto/FAQ?
No need someone else already did... Google is your friend!
> Does anyone have a manual for this card?
Not sure if this one matches your cards?
IIRC, Win95 has built in support. NT 4.0 has built in support
(and auto-detects it, unlike the SK-Net FDDI adapter). Uses Npmca.sys for
the driver. I tried a while ago to find the diagnostic program for the
adapter and failed. Anyone? Editor - Andreas Kohl foundt them...
NP has since been bought out, and the new company has extremely limited
support for NP hardware, mostly switch related. Nothing microchannel. Still,
for FDDI networks, it is my preferred adapter.
Support for Multi Channel Architecture
The BSI-2 device provides three Input Channels and two
Output Channels, which are designed to operate independently and concurrently.
They are separately configured by the user to manage the reception or transmission
of a particular

Modes and Interrupt Level
WARNING : DATA STREAMING
MODE should be selected ONLY if you are sure that this machine supports
data streaming. This will result in better performance. SLOW
MODE should be selected if this FDDI adapter is installed in
an older Model 80 that has not had the IBM EC applied. (Ed.
I think this refers to the non-busmaster

Using arbitration levels, this adapter accesses memory
directly without burdening the computer's main microprocessor. An arbitration
