Ok, that's probably the same. At least the date matches.

Too bad. So likely all PPCBoot's from 2007 on are affected. Don't know
about the 2006 machines. My 2005 PPCBoot has no network support, but
saveenv works.

Yes.

To make your DS-207 boot standalone, automatically, you will have to
replace the Linux kernel by altboot.img, which fakes a Linux kernel in
PPCBoot-image format.

The other problem is that you can no longer pass arguments, besides
using the interactive mode. altboot.img will default to booting "netbsd"
from your first disk drive.


For the documentation (I'm currently updating it): which addresses are
used in your default bootm command in the bootcmd environment variable
(printenv), i.e. which is the address where the Linux kernel is stored
in flash?
