Thanks to all who responded.  Apparently I was doing nothing wrong when I
tried
b sd(0,30,1) 
on our old 4/430 box, which was the obvious (and documented) command.  Most
of you suggested this.  Others suggested the commands which work on desktop
systems:  b sd(0,6,2) or boot cdrom.  Special thanks to Torsten Metzner,
who also sent me an extensive description of the SCSI subsystem (including
how to get to the numbers above).
Nevertheless, I still wasn't able to boot from the CD-ROM drive.  I'm
assuming that I'm facing some obscure hardware failure, as some suggested,
or maybe both bootable CD's I tried are damaged.  Anyhow, it's time to
throw the old box away and start saving on my electricity bill.
