FreeBSD has always supported the root file system anywhere on the disk. The issue is how you get FreeBSD started: you need the BIOS to load the kernel. Many older BIOSes were restricted to the 1023 cylinder limit you mention. It always works as long as the root file system is entirely below the 1023 cylinder mark, regardless of how large the FreeBSD slice is. But it's possible it's not a problem at all: as far as I know, this restriction doesn't apply to any BIOSes made in the last year or two. There's only one way to find out for sure: try it. If it doesn't work, it at least shouldn't break anything, though you should always make a backup before installing a new system if there's anything of value you want to leave on the disk. > I might have my slice and partition definition switched.
