lakes the expensive raid5 engine. still i use it happily

during my last/first/only time i had to deal with ataraid, and IIRC,
the promise IDE driver had a compile time flag where it would not touch
initialised raid arrays.
aktivating this flag would simply remove the offending disks from the
list of ide disks and make it available via ataraid only.

OTOH I might have had a too long day and my memory is all wrong.

lukily I don't have to deal with this box any more ;-) and therefor can
not check this.
