What version of qemu? Platform and how are you running it?

Probably the best thing to do is packet capture the VM and see what it sees.

Otherwise you’d want to modify the source so slirp is writing a capture file of frames in and out. something I should do one day, if anything for myself. At least a usermode version of slirp let’s you build and debit it separately too

Heh just google around for the magical string c7200 is mz and I’m sure you’ll find images in no time. From there re-google any image name and you’ll find more.

I’ll do one better, ages ago I not only setup a DecNET with IOS via Dynamips, I even ported over Synchronet to run on it! And of course Pathworks on NT to talk to VMS. It’s fun I can create not only virtual networks, but even virtual companies.

The next thing to do on Windows is to see why 64bit JIT is broken, something with word sizes being more 32bit friendly I think, and having to check Dynamips to make it more strongly 64bit typed. ..

And so you did.

Where did you get the image of IOS for it?

One fellow on that list for running a network of DEC built computers got it to work, and then got the images from an even more involved fellow on the same list.

However he runs FreeBSD and those DEC systems, and of course the Mac’s chosen OS.

I mentioned it here. It really was quite trivial, I’m more surprised that nobody else got it running.

I can probably find the explanation in my collection of e-mail.but some people may not be so gifted.

I should also mention that this is good news, and OS/2 users should feel extremely gifted with something else….
