I had a similar problem.  I was attemping to load FBSD 2.1.5 from the
Walnut Creek CDROM.  I spoke to Jorden Harbert (Please forgive me if I
mis-spelled your name Jorden).  When I told him that I would get the
message "unknown phase" he said FBSD could not "read/use" my cdrom.  I
had a cheap 2X IDE (generic brand) cdrom.  My solution was to purchase a
new IDE cdrom.  I found a Sony CDU311 8X EIDE cdrom for about $105.00
USD at a local computer shop.  That solved the problem.  I hope this
helps.  Oh, one other thing, make sure the cdrom drive is the slave
drive.  I've heard this is the only way FBSD can use an IDE cdrom (don't
quote me on this fact, as I have no proof this is true)
