I have read a comment (I think in comp.sys.amiga.hardware) that says that it is impossible for PC floppy drives (or at least controllers) to read Amiga disks because the Amiga disks are read a track at a time, rather than a block at a time. There is also no filesystem available for FreeBSD that can decipher Amiga disks that I know of. I believe that there is one for NetBSD, but I think that might only work on m68k computers. A program/filesystem would not be that hard a task for people familiar with the Amiga filesystem and the FreeBSD FS interface, but there is of course the problem of endianness to consider as well. The hard part is simply getting the disk image in the first place. > I'm currently running 2.2.2-RELEASE (yah, could be newer). Would an > upgrade help?
