Running. Building was fine.

Yes, for Mac support etc. Unfortunately it doesn't work for me. For
starters. it does not identify my chip correctly, it says it's a
FAS100A (it's actually a Symbios Logic 53CF94-2 which is more like a
FAS236).
But after I fixed that it still doesn't work.

One difference between the new driver and the old one is its support
for tagged commands. I haven't found an easy way to disable that yet
though.

Would be cool... Last time I went to something like that was the
Oldenburg meeting of 1998 ;-)

I don't think that was the issue. Roman Zippel provided a patch which
fixed it, but his last comment on the matter was

We never got to that, and Roman seems to have disappeared.

Thanks, I'll try installing a more recent Debian on my Amiga.

Kind regards,
