I don't believe the UC07 writes any MSCP parameters to the disk so it 
should work. IIRC, some of the earlier CMD SCSI controllers wrote into 
block 0 the parameters that you told it during config. Also the UC07 likes 
to know which SCSI targets are CD-ROMs vs those that are r/w disks but I 
don't believe you have to tell it that.

On an unrelated note, once the CD booted on the KZQSA, were you going to 
install on to disks also attached to the KZQSA? The DSSI controllers are 
not supported.
