As far as I was able to determine, when I looked into this in the autumn, the only support for the Catweasel under Linux is via a special driver called cwfloppy, NOT the normal floppy driver. This works with Amiga disks (and has limited MS-DOS support) only, and only for the ISA version on x86 and Alpha machines. Quote from the Catweasel page, ISA version section: 'Writing to disks is only possible under Linux at the moment. The drivers are not designed to be easy-to-use. Instead, they are tools "for-freaks-only". You can read disk images from the formats listed above, and single files can be copied from Amiga, PC and C-64 disks.' If you look at the driver homepage, it doesn't even mention C-64 or disk images. There are some additional utilities to allow it to do things with TRS80 disks, though. -- Pete Peter Turnbull Network Manager University of York
