Hi

In my system I didn't bother with any of embedded file systems - I've
created 1 GB ext2 partition (journalising in ext3 increases read/write
count), and it worked just like any other hard drive. Bios detected
correct capacity - I was lucky with that, but in case where BIOS doesn't
detect CF card properly google is Your friend.
I don't have all doc I've used during setup but I remember reading this one
http://silent.gumph.org/content/4/1/011-linux-on-cf.html

regards
