I could prbably boot an older (4.x) FreeBSD on that machine but that would be CD record, too. Medium is also a 80 min 700 MB CD. Weren't they 650 MB in earlier times actually? Earlier times I mean, when I still had my FreeBSD subscription and got each release in a neat CD set :-) Oh well, I will give it another try and see how it works out. Later -- Christoph
