  Problem Booting from (unspecified) CD-ROM? 
 The Question is:
 
I am attempting to build a virgin 3100 with a VMS 6.2 Binaries CD-ROM. The
 system boots from the CD and I get the Stand alone backup $ prompt but when I
 try to issue the backup command it reports the CD-ROM as being offline and
 starts a mount verification
 which never completes. Can you advise?
 
 
 The Answer is :
 
  Your VAX system has non-functional, invalid, or misconfigured
  hardware.
 
  Most likely, an invalid or unterminated or otherwise errant SCSI
  bus configuration, or your (unspecified) CD-ROM device is not one
  that is supported by OpenVMS.  (As referenced in the OpenVMS FAQ,
  OpenVMS requires a CD-ROM device which supports 512-byte blocks.)
 
  There are more than twenty different VAX systems with the number
  3100 within the model name.  (There are a number of DIGITAL systems
  based on the MIPS processor which also use the 3100 numbering,
  though these systems are obviously not supported by OpenVMS VAX.)
  Various of these systems have differing SCSI and console limits.
 
  Please contact your hardware services organization for assistance.
