I guess I am not 100% sure what "termination" means or how to check this ...

I am also not quite sure how to find out about the id, but I remember having 
seen "7" in some menu, so I tried the thing with 7 (and 
with /proc/scsi/scsi, /proc/proc/scsi did not work). It replied with:

	scsi add-single-device 0 0 7 0

'cat /proc/scsi/scsi'  says:

	Attached devices: none

'dmesg' says in the last two lines:

	scsi singledevice 0 0 7 0
	VFS: Disk change detected on device 02:00

That made me optimistic, but when I tried to check this cdrom mounting thing 
again I was reminded that I still don't know which command to use 
since /dev/cdrom does not exist and I am just blindly copying commands ...

I don't know, had a look in the manual but the model numbers there seemed to 
refer to different models of the computer which come with or without CDROM. And 
then someone might have put in another one, and I am not exaclty anti-static 
today, quite the opposite with this god-knows-what-its-made-of pullover, and 
usually afraid of opening any computer cases ... a fear I will have to overcome 
soon ... but not today if might break something that I cannot pay for ...
