Obviously, the install on the Tiny disk is a no-go, so I decided to do it manually. Ok, so using Disk Manager I converted the empty (00) 10M DOS partition 3 to A5 (DOSPTYP_386BSD) and booted Fixit. It hangs after ``using fd0a as root device'' (or a similar message). The Tiny disk does likewise. Next step, attempt to change 00 -> A5 _after_ booting Fixit, by a clever use of dd(1): read in the first block from /dev/rwd0d into a temp file, overwrite the 00 with an A5 from another file (clever use of seek and skip here), and write the modified block back to /dev/rwd0d. Problem: You can't _write_ rwd0d. dd fails, as does cat > /dev/rwd0d. So I'm stuck. Could anybody who has made a small 386BSD partition that co-exists with a DOS partition please send me some mail!!!
