cdrom issue

[Fausto Saporito]

Hello all,
I think there's a problem with the latest changes about cdrom handling.
I tried, with my IDE configuration without diskdevice so using diskfile, to boot from OpenVMS 8.3, but if I specify cdrom=true, es40 crashes without a clean exit.
If I specify cdrom=false, the boot starts fine.

Now, cdrom=true enables the 2048 byte blocks, while cdrom=false reverts to the old behaviour, 512 byte-blocks, so with 2048 byte blocks something generates a fatal error.

Here's my working conf file (just the IDE section):

  pci0.15 = ali_ide
  {
      disk0.0 = file
    {
      file =          "img\dka0.vdisk";
      serial_number = "VMS";
      rev_number    = "8.3";
      model_number  = "OpenVMS8.3";
      read_only     = false;
      cdrom         = false;
    }
       disk1.0 = file
    {
      file =          "img\vms83.img";
      read_only     = true;
      cdrom         = false;
    }
  }

Hello Fausto,

With the current IDE emulation, cdrom=true is valid only on the SCSI controller; on the IDE controller it is broken. Brian Wheeler is working on a new version of the IDE emulation that supports DMA and ATAPI, but that isn't far enough yet to replace the current IDE implementation.

So for now, always use cdrom=no on the IDE controller.

Camiel.
