CD-ROM on VAXstation 3200

Hi! I'm trying to boot my VAXstation from CD-ROM since I don't have a tape drive. It has an Emulex UC08 controller. The internal hd and an internal MO drive are connected to the first port, to the second port I attached an external Plextor UltraPlex 32. I updated the UC08 to rom revision G143R, just to be sure and configured a cd-rom drive on the second port, scsi id 1. When I try to boot from the CD, it is ejected after a few seconds and nothing more happens. Every time i put the cd back in it is ejected again. The same happend when I tried a old SUN caddy CD drive (Sony OEM). Any hints? Regards, Sebastian ---------- This is what the machine spits out: UQSSP Disk Controller 0 (772150) -DUA0 (RA81) -DUA1 (RA81) -DUA2 (RRD40) UQSSP Disk Controller 1 (760334) -DUB0 (RRD40) Ethernet Adapter 0 (774440) -XQA0 (08-00-2B-10-1B-D5) (BOOT/R5:0 DUB0) 2.. Here it ejects the cd and hangs forever.
