Special Note

I added the "Special Note" section at the bottom of the page out of a sense of warning to my fellow Collie users. OZ is basically worthless on Collie unless you move root to an SD card. If that procedure is discussed elsewhere on the site, there should at least be a link to it. --JTD 20:49, 26 April 2006 (BST)

I added a link that seems to cover this but I haven't tried any of this yet. 70.187.178.60 07:17, 25 May 2006 (BST)

Partitioned CF-Media for installation

I just succeeded installing OZ on my Collie using a 128MB CF with one partition covering the whole media. B.D.

I have also had repeated success, flashing from a 1GB microdrive (with 1 partition, /dev/sdb1)
