OK, I found and fixed the error. The problem was that our low memory support didn't get turned on for Cobalt machines with 32 MB even though they need it... new images are now at http://people.debian.org/~tbm/d-i/images/mipsel/daily/cobalt/netboot/ I'm doing an install in 32 MB right now and it works fine. Can you try this new image and tell me if it works for you?
(Just a little note: if you choose unstable it should just work; if you choose testing, you'll get one error message about low memory failing, but simply ignore that and choose the partitioning tool and continue; it will work.) -- Martin Michlmayr [EMAIL PROTECTED]
