There's a new dream team on the block.
That may be you, your favorite PS/2 and your IBM 10/100 Mbps Ethernet Adapter (9-K)!
After weeks and months of reverse and forward engineering, we now have drivers for this very late manufactured, 32-bit Micro Channel 100 Mbps capable Ethernet Adapter type 9-K, code name "San Remo", that IBM released only for the RS/6000 series as one of
the very last MCA cards.
For 30 years there were no drivers outside of AIX, IBM's proprietary Unix operating system.
Today you may start running it in Windows 95, probably also 98, and Linux 2.2! Get your copy here:

And as our friend Shane pointed out:

FYI, there’s a seller on eBay that has >200 of these in “new, bulk” condition for ~$60 shipped and shipping costs drop if you buy multiple cards.

...and shipping costs drop if you buy multiple cards.

I'm prompting for how much shipping "and handling" costs can be reduced for multiple adapters - Us Yanks could probably have four put in a USPS box shipped for far less than $140.

Cool stuff, will definitely try it out on a 9595 or server 520 and
report back. If only I had a little more time to play around with MCA ...

The problem with using a 9-K in an Intel system is the processor load.
On a 7030-3BT I have about 4.5MB throughput with a comparatively
sluggish AIXwindows. A 9595 will not achieve this. As soon as a GUI
comes into play, the 90MHz Pentium will go to its knees.

In any case, thank you for your work, which I greatly appreciate!

New link with "Make an offer": https://www.ebay.com/itm/196091827841

The seller seems to be willing to sell multiple adapters (from two up) for $20 each, and is negotiable on shipping using UPS (U.S.-based buyer) for far less costs than on the auction listing...

Why? It's a DMA enabled card.

Ryan

Interrupt rate - not sure if the card has batching or moderation
available (this would be on the PCI side) - that would help a lot.

I hope it works for all of you without any headaches.
If you would like to benchmark it (honestly, I would like you to benchmark it!), I've created a zip file containing matching versions of the netio benchmark for Win32, Linux, OS/2 and AIX that should enable most of us testing the adapters in our favorite
environments:

http://www.holzapfel.biz/8F62/netio132-ibm.zip

Just start one executable on a connected powerful computer with the "-s" parameter to start a server, then run the executable on the Micro Channel machine using the "-t <server-ip>" command line argument.

So my switch shows 100MB FDX, I did the test again with sysmon showing CPU usage in Windows 95 and it's 100% CPU with the 9-K. I am pretty sure I'm just maxing the CPU at this point in terms of top end speeds.

For some reason the Reply TurboProcessor is a slow board despite the Syncrostream controller. A Pentium OverDrive at 83Mhz on a TurboProcessor 60/80 is about 20% slower than most online benchmarks of the same chip or any rando 486 board and even my own
IBM PS/Valuepoint 433SX/X (Type 6382), http://ps-2.kev009.com/pcpartnerinfo/ctstips/3aa2.htm, which just stomps the shit out of the Reply TurboProcessor in terms of performance. I've never used the benchmark tool Chirstian provided, maybe this weekend I'
ll compare it against the Valuepoint which has a 100mb 3com ISA card.

Any chance you measured the CPU usage when benchmarking the 3com card?

Our glorious tool https://ardent-tool.com/NIC/Ethernet_Bench.html#Results indicates 28.1 % load with the 3C529 on a 486SX-33, doing around 950 KB/s (under Linux!).

The Lacuna has a BIU, not a SSC.

Yeah, the Reply may have an actual SSC, but how much did IBM "tweak"
it?Sordid reminds me of the T/R chipsets that IBM fabbed for third party manufacturers.

How about a little M or Type 4 hot n heavy action?

What's interesting is the mixed performance on the RS/6000 systems. The later mid-range workstation machine with a faster CPU performs worse than the early 1992 high-performance server class system. I assume, the 7013 was built specifically for high-

throughput and low-latency applications.


In particular, the memory bandwidth is insane on the POWER2 systems.
The MHz is also misleading, it is a superscalar processor with 2 integer
units and has double the cache (10ns I believe). It would be
interesting to compare the context switch time of the PowerPC.

That the Lacuna and Reply perform so low is disappointing, but maybe there's a reason why IBM did not sell this adapter to PS/2 users - or maybe we will find a magic switch to make the card operate faster.

I suspect you may be able to profit from games with the tx and rx
interrupt masks.. the Linux pcnet32 driver looks like it has a (limited)
poll mode which would be preferable to dealing with an interrupt for
every packet on this old hw.

With your driver, the 9-K is three to four times faster than the
Etherstreamer MC32, which was up to now the fastest Ethernet adapter for
the IBM PS/2. The system remains responsive even if Sysinternal's
process explorer claims 100% CPU utilization.

Well done!

Will try your Linux driver with Slackware 11 and the second release of
your W95 driver as soon as possible.

Well, there are different amounts of RAM.

What effect does adding RAM have to performance? Where is the sweet spot?

What are the chances of a DOS driver?

The leaked sources for the original PCnet DOS packet driver are around.
They are plain x86 Assembly, processed by

# MAKE Version 3.6
# TASM Version 3.1
# TLINK Version 5.1

Generally, the places such a driver needs modification to work with our 9-K are well known to Ryan and me and properly documented now - but I'm not that fluent in Assembly (yet).
Furthermore, the DOS driver is working in 16-bit mode only, while the 9-K ASIC and also the PCnet chip in our case need some 32 bit addressing.
So it's a little more to it, but generally doable.
Maybe in the boring, gray start of next year I could look into it.
If someone else is willing to pick that up, I'm happy to help :-)

I've been pretty decent writing code for c# and such, but not sure if I could pick this up and be useful. I'd have to start reading about it and see.

As far as the 9x driver, I have been unable to get the updated driver working at all. Even with a fresh install of Windows 95. I'll get an IP but can't ping the gateway, the reply times out. I didn't change any of the default settings of the driver.

.. I think the buffer or whatever was set to RX + TX. This weekend has been bit busier than I expected and I have to run so.. not sure how much I can play with it more this weekend. Also... with the fresh install, the 32bit driver for my BusLogic card
is intermittently loading... which what the hell?!?! So I want to nuke the install again and find a more trusted ISO of Windows 95 C. Downloaded some fresh copies last night and had one fail that it couldn't find a file in a cab in the middle of the
install... turns out people commented on the download page that the ISO was wonky. I dont burn the ISO's to CD-R as ZuluSCSI will emulate them as a CDROM if you put the ISO on the SDCard and name it properly.

Anyway, with the fresh install, performance was a tad better. I truly think the reply board is slow in general. The 486 Overdrive 100mhz and Kingston TurboChip also both score about the same as the POD83... which is 20% slower than any rando board

out there that can take these chips. I've had a few others with the Reply board get the same results. Not sure why.

I keep having the suspicion that these are passed to the PC-Net

Would be cool to see what the ASIC parameters are on your AIX server for the fields we aren't able to infer their meanings. Maybe a project for next year when your time allows.

So from the hardware point of view, the only difference is that in the 9-K case, the hardware access is tunneled through the PC 750's PCI-to-MCA bridge, and then through the 9-K's MCA-to-PCI ASIC bridge.

My guess is a timing problem in the PCI-to-MCA bridge. May I ask you for another test run? The PC 750 supports a PCI bus clock of 50MHz. I could
imagine that the MCA bus would cope much better with this than with the
66MHz bus clock.

The AMD K6-III can handle an external clock of 50MHz according to the
PowerLeap upgrade manual:
https://ardent-tool.com/CPU/PL-K6-IIIv2.pdf
It then runs internally at 300 MHz. That should be enough to get
100Mbits out of the LAN.

With a 50 MHz base clock instead of 66, the adapter tops out at ~6700 k/sec:

Hmmm, very silent here. I hope I'm not the last man standing.

After a lot of fiddling with the kernel source code I have found a way
to establish a reliable and persistent network connection under
Slackware 11, Kernel 2.4.33.3. The solution to the puzzle here was to
build the network driver as a module, to load the module via /etc/rc.d/rc.netdevice and assign a static ip configuration via /etc/rc.d/rc.inet1.conf, /etc/resolv.conf and /etc/hosts, ymmv.

Involved was a 9595A, P90, 256MB RAM, now with a 10/100 network link. A
big thank you to all who were involved in the driver development and
especially to Christian, who sent driver patches and was patient with me.

Here are the netio 1.30 client results.

The patch and C-file won't work with a 2.4 Kernel out of the box.
I already started porting the sanremo.c to 2.4, but it's not final yet, I have no patch and corrupted my 2.4 Linux partition >.<
I can send it to you for further testing. It's not fully cleaned up, but should compile and give a connection.

Interestingly, the 2.4 Kernel seems to tackle some performance issues: It now seems to hand the network subsystem buffers straight down to the card for DMA.
Seems to only profit in one direction, and degrade in the other.

This is what I measured on an 8595 with Pentium 200, Kernel 2.2:
