Also - Z2 memory willbe slower than a moderately fast disk.

A good idea.

> There are also some dummy drivers included for the USB and the microSD card reader of the ZZ9000. But, they’re just skeletons for future driver development. As for today, the ZZ9000 with firmware 1.5. does not seem to expose the required register-sets for these functionalities.

This shouldn't be necessary (why doesn't the card have its link
address in the firmware?)

You can configure that with ifconfig.  and ist stylistically the
wrong thing to do - you could boot two machines with the same
kernel...

paraphrased from "man ifconfig"

ifconfig zz0 link 68:82:f2:00:01:00 active

or put it into /etc/ifconfig.zz0 to be automatically set at boot time
as the first configuration option

link 68:82:f2:00:01:00 active
up
inet ....
inet6 ....

Sorry I didn't comment anymore on your older driver, I'll start with this
one. It have been very hectic weeks ...
