im trying to install freebsd 7.1 on an x86 machine with a 4.5tb 3ware raid array. however when i use one large slice it wont boot, and if i use a smaller slice for the os (~20gig) then create a seperate slice for the remaining space, it boots however despite fdisk and disk label saying this mountpoint should be ~4tb it comes up as ~1.8tb. is there a work around for this?
