Well, Dave, you're the first one who tries to run 2.2.1 on a DS 5k/200 so
this is not going to be a matter of compile'n'go.

The first thing you'll have to check is wether Thomas Riemer's dz driver
works for your /200 too. We don't have any framebuffer console drivers
actually, so please make shure to have support for serial console compiled
in (Virtual Terminal=n, Serial support=y, console on serial port=y,
DZ11=y). I'm not familiar with Tom's dz driver so you may need to pass
command line parameters to the kernel (console=ttySx, with x=[1,2,3]).

Things that definitely will need some hacking are the Ethernet and SCSI
drivers. Ethernet should be relatively easy but SCSI will need some more
work. Fortunately some guys including me have a PMAZ-A card so you're not

If you have further questions, fell free to ask me.

Happy hacking.
