just tell kernel which devices to use for your root filesystem
(if your root is on raid device), by using something like
  append="md=2,/dev/hda1,/dev/hdb1"

I have some partitions with the fd type in raid arrays but would like to
switch to the manual method you just described. These partitions hold
data I care about. Is it safe to change the partition type:
   - while the array is not active?
   - while the array is active?

Thanks.
