We've Got Another Live One!

OiveBSD is another "LiveCD" BSD version, this time based upon OpenBSD.  A LiveCD is one where you can boot and run the OS via the CD, which lets you test out things like hardware compatibility.  Usually, although not always, you can also install directly from the CD.  There's been some call for a PC-BSD LiveCD, but I think the developers are correct when they say that a LiveCD for PC-BSD doesn't offer you anything over any other FreeBSD LiveCD, like Freesbie or roFRESSBIE, because the thing PC-BSD does best is to streamline the install process.  So if you want to make sure PC-BSD will work on your hardware, try out one of the FreeBSD based LiveCDs and see how that works.  If you're happy with it, go grab the latest PC-BSD and go to town with that.
