This patch allows to define where is connected the CDROM device (bus,
unit).
It extends the "-cdrom" syntax to add these paramaters:

     -cdrom file[,if=type][,bus=n][,unit=m]

 where "type" defines the interface (by default, "ide")
       "n" defines the bus number (by default 1)
       "m" defines the unit number (by default 0)
Having a separately named arg just for CDROMs was always rather odd/unhelpful. I'd suggest that we leave all the -hda,hdb,hdc,-cdrom,-fda,-fdb etc unchanged and use the -disk for setting up all types of disks, floppys, cdroms, etc. It
would just require one extra field for the -disk arg:
      -disk file[,if=type][,bus=n][,unit=m][,mode=mode]
   where "type" defines the interface. [ide,scsi,fd] (by default, "ide")
        "n" defines the bus number (by default 1)
        "m" defines the unit number (by default 0)
        "mode" defines one of [disk,floppy,cdrom]
If we ever up able to emulate other types of SCSI / IDE devices (tape drives,
cdr, dvd perhaps) then the 'mode' can easily be extended to cover them.
I agree with that. And if everyone agrees I can modify patches to do that...

Please go ahead. :-)

Well, it is done... is there someone that can comment them ?
Or if they are perfect (as usual ;-) ) perhaps it could be included in CVS ?

Regards,
Laurent
