Just stopping by...

Anybody having any issues with the IBM Ultimedia Sound Windows NT
driver? Card ID DFE5.

I still have the AMD source code for the AMD chipset that is used on
the 100 TX IBM MCA network card that I got after cracking AMD's zip
file password. If we have any new programmers in the group that have
time and want to get down and dirty with it, it's all yours. If
you've ever used the card on a RS/6000 MCA you know it FLYs when doing
file transfers.

Enjoy

As noted before, the problem in writing a driver for this card is not the
AMD PCnet32 chip on this card - it's well documented in data sheets from
AMD and there are open-sourced Linux drivers for it. I myself once wrote
a driver for a PCnet32 chip from the same family (newer variant with
integrated PHY) for our router OS at work because Hitachi used it on an
evaluation board for their SH7751 CPU.

The tough job is the Adaptec chip that does the bridging between the
Microchannel bus and the PCI interface of the PCnet32. To access
the Ethernet MAC, you have to go *through* this bridge chip, which is
difficult if you know nothing about it.

My current guess is that the only possible source of information about
this would be the source code of the AIX driver for this card. If anyone
has access to AIX sources, I'd be more than willing to look into this
issue - I have myself a useless 9-K lying around that would be a perfect
replacement for the less-than-perfect Olicom 2335 in my server...

Best regards

Alfred

The bridge chip does the magic for us. We know how to config the
bridge chip to give resources to the card. So the only thing we don't
know is what register in the bridge chip to clear the interrupt. The
rest with your expertise on the PCnet chip is I/O mapping. Has
anybody ever tried in debug to clear the interrupt on the PCnet side
to see if the bridge chip passes it through??

Hi,

Should I have missed any information about this card, feel free to send me
links to it. The last thing about the 9-K I saw was a rather minimal ADF
file mapping a small I/O window - too small to hold the PCnet32's full
register set, and back then when I looked into the contents of that I/O
window it didn't look at all even like a part of a PCnet32's register set.

Mine still works well in a Model 90. I've since come by a few more that I
have not yet done anything with.

I now have one of the cards, thanks to Louis. So if anyone picks up the
torch and needs a tester...let me know.

I think the answers are here. Anybody know these guys? They've seen
the source code based on what they say in section #2.
