Frustrating was, how ever, that most trouble I run into, I can fix. Doing FreeBSD for so long, makes that I don't easily give up. But after 4 hours of fiddling with bootsectors, loaders, setting and what not, I gave up. Also because I did not want to jeopardize the data. (It is on backup, but the backup was already 8 hours stale) But hey, system is backup. And haven't heart anybody complaining about missing data, of other failures.... --WjW
