I hope you forgive me a non-MorphOS posting, but at least this is an off-topic group, and I hope to reach most Pegasos users in this forum.
NetBSD/ofppc supports the Pegasos2 hardware perfectly since quite some time (including Firewire, Gigabit ethernet, etc.). Since last month it also supports RDB partitions, to allow users to run MorphOS and NetBSD in parallel on the same disk (in different partitions).
Something which was never tested is to run it on a Pegasos1. To find out how much work is needed to support the hardware it would be great when there are Pegasos1 users who have some time and interest to try it out, and are skilled enough to analyze and describe the problems they encounter.
Anybody who is interested can mail me. I will provide them with recent bootloaders and test kernels.
