I picked up a PC theses days, a HP DC5850. My plan was to transform this PC on a BSD Box, using a triple boot of FreeBSD, OpenBSD and NetBSD. But i cant, for some reason this machine have a bug in the bios that freezes the FreeBSD and OpenBSD boot process, this bug is well know and related but is not fixed yet. Linux and NetBSD runs fines. I don't have the knowledge to fix this bug, maybe in the future.
