All of the BA440 based 4000 models 200/300/400/500/600 will boot from an
RRD series drive on a KZQSA. I have a 42 and a 46 and both work.

The KZQSA was the controller that generally was used to attach a SCSI

posts on here indicating that you could also use it for a single SCSI
disk, and it mostly worked, as long as it didn't have >1 device on it.
Yes, it's useful to have a KZQSA if you want to boot from a SCSI CD-ROM
and install VMS.
I believe a KA655 (3800 / 3900) won't boot from a KZQSA, but a KA660
(4000/200) will.
