Disks are not bad. Works with other OSes. Problem is with FreeBSD. I've tried versions 4.6, 7.2, 8.0 and 9.0. Only FreeBSD 4.6 boots without hanging. I've not tried 5 or 6 but I guess I could if it would help to narrow down what the changes were in those versions. Something obviously changed along the way to cause it to hang.
