It is advised to use an ISO image instead of a real CD.
- On Windows you can access the real CD by a name like “\.\Cdrom0”.
- On Linux it is usually /dev/cdrom.
To boot Tru64 or OpenVMS from the CDROM.
- Add a CDROM to the configuration, set its SCSI BUS, SCSI ID and the file/device name. For the CDROM to appear as DKA400 set SCSI_BUS=0, SCSI_ID=4, SCSI_LUN=0.
- Run the VM. It will show the SRM console prompt
- In that console prompt you can type commands like
show devto see what devices are seen by the VM’s firmware.
- Determine your CDROM device name and run a boot commands like
boot dka400. The system will boot from CD. The device name depends on the selected SCSI BUS and the SCSI ID of the CDROM device.
