Re: How to enable a SCSI CD-ROM ?

Hi!

Unfortunately, i have not yet found the time to read the messages in your
other thread.  So, I hope I'm answering the correct questions here, being
a bit out of context.

    $ showtrans /dev/hd2
    /hurd/storeio hd2

Thus you'd need something like this:

    # settrans -cfgap /dev/sr0 /hurd/storeio sr0

... assuming that sr0 is the Mach device name.  You can check if such a
device exists:

    # devprobe hd0
    hd0
    # devprobe moo; echo $?
    1

Also, there is a /dev/MAKEDEV script.

Not required.  But you possibly have to take care to deal with replacing
both active and passive translators at /dev/[...].
