Tonight I pulled the 4000D down to install 16MB on the mobo. Way back a long time ago I had pulled the 16MB off because I had been told (erroneously, unless it varies by accelerator) that the 16MB would be higher priority than memory on the accelerator.
I told you that to tell ask you this. When I booted up and checked on the system (happily finding 144MB FastRAM) I noticed that the X-Surf reports as Zorro II. Even though PCI expansion boards probably make this a moot point, I pondered as to whether a Zorro III X-Surf would be fast enough to support 100Mbps, or at least fast enough to fake it?

AFAIK there are very few (no?) 100Mbit ISA NIC's and so the conversation is moot.
The X-Surf uses a 10Mbit ISA NIC (1.25Mbyte/s) well within the bandwidth of it's ISA to Zorro II bridge.

The X-surf cards are only ZII

I think that LoadWB knows that. I believe he's speculating whether it would be possible to make a 100Mbit Zorro III ethernet card that would take advantage of the higher bandwidth available and work at 100Mbit speeds.
One of the reasons that Jens Schoenfeld did not make a ZIII version is that it would have limited his market. It would not have worked in Amiga 2000's or towered A1200's.

There is, and I've written a driver for a zorro II prototype. Unfortunately, the TCP/IP software usually is already at its limits performancewise, and except for having a 100MBit endpoint, the speed gain is indeed moot.
Things might be different with Zorro III DMA, but this is a bit tricky. In any case you need to be using a different TCP/IP stack than MiamiDx (hey, where's Roadstar 68k, wasn't it to be release 5 years ago?), which is already at its limits when doing NAT/Gateway/PPPoE functionality below 100KB/sec with a 68060@50MHz. I haven't been able to push Miami above 800KB/sec at any settings.

Does anyone know if Jens is still around, alive and
well? The end of last december he sent mail asking for
my snail mail address so he could send me a replacement
chip for my "still under warantee" XSurf II. He said
he'd send it right after the first of the new year.
Since then I haven't heard a thing. No response to
multiple email's. I even sent mail on his web site,
no response. I dont understand why he'd ask for a purchase
invoice, offer to send the chip that went bad, ask for
my mailing address, then withdraw product support with
no explanation.

Many years ago I messed with an ISA 100 Mbps card in one of our - even then ancient - Netware 4 servers. I got it to work more or less but the performance wasn't exciting.
As Chris wrote, there's not much point in having a 100 Mbps connect reported that is no faster than a 10 Mbps connect.
I'm currently fiddling around with my new Prometheus bus board (anyone's got a spare Voodoo 3?) and a RTL8139, but I have no hope that throughput moves beyond 1 MB/s, if at all.

Chris, did you ever get that PCMCIA PC-Card USB Host I sent you? (Through Michael Boehmer).

Didn't Olaf say in one of the CAM's that he had an agreement with Hyperion that Roadshow 68k wouldn't be released before OS4 (IIRC, there was a date clause too)?

@BR

I think he's been posting on the comments of the news item about Clone-A.
-
Ok, thanks! If he's posting he must be alive and
well. >:)

i can't get more than 800-830Kbps me too (X-Surf2 on LAN) with MosNet 1.2 and MOS for PowerUP :-/ funny thing is that i'm now on an ADSL2+ internet connection!
I would love a 100Mb NIC card but as Chris said...
-
@platon42
Genesis is slightly faster than Miami and should give you more speed.

Are you sure it's a RTL8139? AFAIK only RTL8029 is stable with the current firmware.
-

Indeed I saw it and held it in my hand once and it looked pretty nice. Unfortunately, I don't have a machine with a PCMCIA port that would fit this kind of card. If'd send you the docs and maybe even a framework, would you be able to write a low level driver for it yourself?
-

I can remember things that long ago. All this quarrelling and fighting should have been over long time ago. But as far as I know Roadstar, which is Roadshow 68k + Reaction GUI would not have been affected by some Hyperion agreement but was not released due to the GUI code not getting finished... :-(

... I have this nifty USB 2.0 10/100MBit Ethernet adapter here for 20 EUR... ;-)

OpenPCI (http://bvernoux.free.fr/DevPCI.php) has got a pretty brand new driver which should actually work - worth a try since I've got a 8139 at hand.
I'm still looking for a Voodoo though - I've been told that Prometheus doesn't work without a PCI frame buffer serving as local RAM.
Just bought one at ebay, inquired before bidding that it really was PCI, wrote it on the bank transfer and I got - an AGP. sigh... :roll:
