 The atacontrol(8) man page and handbook page on RAID (19.4.2) both 
 discuss (briefly) hardware RAID and say it is supported.
 
 It seems you're calling all the southbridge controllers "software" 
 RAID?  That terminology in my experience is used to describe gmirror/ccd 
 disks without a RAID controller or RAID BIOS.
 
 In any case, the difference and PR still remain.
 
 A 6 disk RAID-10 controller ((1,2),(3,4),(5,6)) with failed disks 1, & 4 
 (or even 1,3 & 5) will boot and allow you to do your 'magic.'
 
 A 6 disk RAID0+1 controller ((1,2,3),(4,5,6)) with failed disks 1 & 4 
 will not boot the OS.
 
 Misrepresenting one as the other in the software is wrong.
