I doubt, that there are DoC's available with 1.8V supply. The stuff looks more like random nonsense. Use a recent 2.6 kernel with the new diskonchip driver. We don't know which kernel modifications are on the Knoppix CD, so please use a kernel >= V2.6.8.1 from kernel.org and if the problems persist the latest MTD patches from the MTD website. tglx
