AmiCDROM with a GVP Hostadapter cause a problem:

You can't eject your CD.

Why?

omniscsi.device (or gvpscsi.device) does only allow an eject, if it is secure.
This means, the motor was turned off (TD_MOTOR). This is not possible with
mechanic eject, but with a motordriven eject, this is possible.
AmiCDROM doesn't care about TD_MOTOR, so ejecting is not possible.

MOff simply sends a TD_MOTOR off message to given device and unit.
TD_EJECT is also sent, but this is not (yet) supported by (omni|gvp)scsi.device.

Example:

MOff omniscsi.device 4

this enables eject for my CD-ROM.
