If you want to boot Linux off pcmcia, you need to add that support to yamon or whatever boot code you're using. If you're talking about using a pcmcia for a root file system, then what you can do is: - build your root fs and dump it on the pcmcia card - create a small ramdisk which you'll statically link into your kernel. Your ramdisk will be your temporary root FS and should contain on it things like the pcmcia modules and socket driver, a script that loads them, cardmgr, insmod, mount, and ... I don't remember what else but that's pretty much it. The kernel mounts the ramdisk root fs, executes your script which does its magic, then control is passed to the kernel which mounts the real root fs on the pcmcia card. Pete
