I much prefer it that way as it > just makes sense on a dedicated box, which is what all of mine are. It generally works just fine. I even have one machine configured that way. IIRC, the problem is that some over helpful BIOS implementations have decided that they should only try to boot disks which don't have an MSDOS partition table on them. This has nothing to do with FreeBSD and everything to do with the morons who write BIOSes for WinBlows. It doesn't hurt anything to slap an MSDOS partion onto the disk so you might as well do it.
