I have a Digital Personal WorkStation 433au with a raidframe
 	root filesystem mirrored between an IDE disk (which SRM
 	can handle) and a SCSI disk on an atw controller (which it
 	cannot).

 	Before making wd0a into a raid component it could boot fine
 	from it. Now, it loads the first bootstage, then fails out
 	saying it cannot load '/boot'.

 	If I netboot the kernel will autoconfigure the root filesystem
 	and run without problems.

 	I've run 'installboot -v /dev/rwd0c /usr/mdec/bootxx_ffs'
 	and even 'installboot -v /dev/rraid0c /usr/mdec/bootxx_ffs'.

# disklabel wd0 | sed '1,/fstype/d'
  a:  17916240         0       RAID                     # (Cyl.      0 -  17774*)
  c:  26588016         0     unused      0     0        # (Cyl.      0 -  26376)

# disklabel raid0 | sed '1,/fstype/d'
  a:   4194304         0     4.2BSD   4096 32768     0  # (Cyl.      0 -   4095)
  b:   2097152   4194304       swap                     # (Cyl.   4096 -   6143)
  c:  17916160         0     unused      0     0        # (Cyl.      0 -  17496*)
  e:   4194304   6291456     4.2BSD   4096 32768     0  # (Cyl.   6144 -  10239)
  f:   7430400  10485760     4.2BSD   4096 32768 54688  # (Cyl.  10240 -  17496*)

 	The only two issues I can see would be:

 	- raid0a has a 32k/4k blocksize
 	- raid0a is ffsv2

 	Can anyone confirm if either of the above would be an issue, or
 	see what I'm missing?

 	Thanks
