In my experience helping out in a freebsd based IRC channel, people have untold problems installing freebsd to anything other than the first partition on the first drive on the first ide controller! I did have quite a few problems when I first tentatively installed freebsd as a 'dual boot' OS with linux on the first partition... as such I removed linux totally and moved over to freebsd - never looked back:) My usual advise is to dedicate a whole machine to freebsd if possible - once you have it up and running you don't want to turn it off anyway :) In general though, you will have problems installing to a partition that is past the 1024 cylinder mark though (although you could try it just to see how much pain it is:). _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ I disagree completely with the above advice. Installing FreeBSD above 1024= cylinders is dead easy. My installation is on the "second" 40gb of an 8= 0gb RAID0 array. Before that, it lived on the second 10gb of a 20gb driv= e, also above the 1024 cylinder mark. The 1024 cylinder limitation is a BIOS characteristic. Since you note that= your BIOS supports LBA addressing, the 1024 cylinder limit doesn't apply= . Just install exactly where you want to. There aren't any extra installatio= n steps or fiddling needed to install above 1024 cylinders. System Comma= nder, grub, the FreeBSD boot manager or the NT bootloader will happily bo= ot FreeBSD from there. Any problems, let us know.
