I started to set up a Pentium MMX 200 based setup, running DOS at least for the time being. As for networking I have 3Com Etherlink XL PCI, model 3C900-COMBO. I have used MTPC as the IP stack for my earlier builds, so wanted to use the same this time. To start with, I downloaded 3Com Etherdisk CD 5.4 from Vogons library:

http://vogonsdrivers.com/getfile.php?fileid=9 … &menustate=34,0

The 3C90XPD.COM packet driver from that package loaded fine, but when trying to run any of the MTPC applications, the system just froze. Recovery possible only via hard reset.

After some research, I was able to find an older version of EtherCD from here:

https://archive.org/download/ethercd-5-1

I mounted the BIN/CUE image, extracted 3C90XPD.COM from there, and that's that: with the older version, MTCP now works perfectly. I'm attaching the extracted packer driver .com and the related config utility extracted from the CD in this message, in case someone stumbles upon the same issue.

I'd be happy to upload also the whole cue/bin image to the Vogons library, but not sure what's the process, so if anyone can help with that, it would be great.
