The recent problem Ive been having is that I can setup a HFS+ volume with a System Folder (blessed) on a CF card using my TiBook 400, but I cant *boot* from that volume either from USB or PCMCIA....When holding down option I dont see the volume listed. And when rebooting normally and checking the volume using Disk First Aid, it tells me that there's problems with the volume.

But I've done this exact thing using my 1400cs, and was able to boot from it. Are NewWorld macs not capable of booting from PCMCIA?
