  Unable to boot V7.2-1 on DPWS-433au? 
 The Question is:
 
I would like to boot OpenVMS on a Digital Personal Workstation 433au. When I
try to boot the OpenVMS v7.2-1 CD-ROM it loads as far as the initial OpenVMS
copyright banner and after about 30 seconds the CD-ROM spins down and the
machine hangs. I can boot i
nto SYSBOOT and alter parameters without any problems, but it refuses to
continue past the copyright banner.
 
This machine has run OpenVMS in the past without any problems (v7.1-1H2).
 
I am running v7.0-10 of the SRM console firmware (the v5.5 firmware CD boots
okay). The CD-ROM drive information from a 'show device' command is:
 
  dkb0.0.0.207.0  DKB0  TOSHIBA CD-ROM XM-6202B  1110
 
This machine has the Cypress PCI peripheral controller installed and will
boot Digital UNIX v5.0 without any problems.
 
  -jon.
 
 
 The Answer is:
 
  It would appear that there is a problem with the CD-ROM drive or with
  the CD-ROM media or with the OpenVMS Alpha V7.2-1 bootstrap or with the
  peripheral devices present in this configuration.  Common sources of
  problems include a CD-ROM drive not capable of supporting 512 byte block
  transfers, and graphics controllers that are not supported by OpenVMS.
  CD-ROM media problems are not unknown.  There have also been problems
  with certain IDE CD-ROM combinations, the OpenVMS Wizard will assume
  this configuration is based on a SCSI bootstrap.  The OpenVMS Wizard
  will further assume that the console bootstrap flags and the OS_TYPE
  are set up correctly for use with OpenVMS.
 
  The OpenVMS Wizard would encourage you to contact the Compaq Customer
  Support Center directly for assistance, as resolving this will require
  rather more information than is available via postings here.
