Well, I hadn't, so I tried it. And since I had read the note: # ATA_CAM: Turn ata(4) subsystem controller drivers into cam(4) # interface modules. This deprecates all ata(4) # peripheral device drivers (atadisk, ataraid, atapic= d, # atapifd, atapist, atapicam) and all user-level APIs. # cam(4) drivers and APIs will be connected instead. I had an idea that /etc/fstab would need a global edit (though I didn't know what device would be used). Attempting a single-user mode boot clarified that for me: :s/ad4/ada0/ Fortunately, I'm in the habit of keeping more than one bootable slice around, so I was able to accomplish that. And -- probably more important for this discussion -- I was unable to re-create the failing condition: the machine booted Just Fine every time I tried it, whether the CD/DVD drive was inserted or not. Now, this seems a bit more like a circumvention or diagnostic aid (to me) than an actual solution -- or am I misunderstanding? Thanks for the suggestion, though! Peace, david --=20 David H.
