[gentoo-dev] IDE ATAPI CD-RW: give the newbies a leg up!

[gentoo-dev] IDE ATAPI CD-RW: give the newbies a leg up!

[Gilles Pelletier]

Isn't it strange that, though almost everybody now has an IDE ATAPI
CD-RW, instructions on how to get them working are very hard to find?

Please don't forget the newbies. Even if they used Mandrake, Lycoris, 
ELX or Xandros, ir won't be much help if they want to learn more with 
Gentoo. Make sure you give them an adequate leg up. Don't forget 
J-C's advice: no strong foundations, no solid building . :)

So, Here are the instructions I wrote using Slackware (I haven't moved 
to Gentoo... yet.) I suppose it would be easy for you to adapt them 
if need be.

-------------------

Add

append="hdx=ide-scsi"

to /etc/lilo.conf
­­­­­
This line loads a module in the kernel for scsi emulation because
Linux normally works only with scsi cd writers.  The x should usually
be replaced by c as the cd rewriter is most often plugged as the
secondary master. If not, it should be b for primary slave or d for
secondary slave.

--------------------

Add

/sbin/modprobe ide-scsi

to /etc/rc.d/rc.modules

This line loads the scsi module installed by lilo.conf

---------------------

Add 

/dev/scd0	/mnt/cdrom	iso9660	noauto,user,ro	0  0 

to /etc/fstab

At boot time, this line in the file system table (fstab) will allow to
mount the cdrom to the mount point /mnt/cdrom .

*********************
For more advanced users:

Notice that, after loading the scsi module, if no other scsi device is 
present, the device for the cdrom is scd0 instead of hdc (for a 
read-only ide cdrom plugged on secondary master.) In some Linux 
distros, a link is made from /dev/scd0 to /mnt/cdrom or other 
mounting point, so that the line in fstab may read something like:

/dev/cdrom	/mnt/cdrom	iso9660	noauto,user,ro	0  0
**********************

The third field means the file system is the standard iso9660.

"noauto", means "Do not mount the device automatically at boot time" .
(On the countrary, your hard disk, which is a non-removable device,
is mounted automatically. The system knows it is there, whereas there
might not be a cd in your cd writer :)

"user" allows any user to mount the cdrom. "owner" would allow only
root to mount it. "users" would allow to unmount the cdrom even if it
has been mounted by another user: seldom used.

"ro" means read-only. Don't ask me why the cd writer has to be mounted
read-only.

"0   0" relates to dumping and checking the filesystem. Forget about
this for now.

----------------

That's it folks! Don't you think, for 99.9% of your users, those few 
lines would do a better job than the 75k outdated howto?

[Thomas T. Veldhouse]

I have given pretty detailed instructions in the past on this list how to do
it, with both modules and with linking ide-scsi into the kernel.  Both work.
Search the archives, it is only a week or so back.

This is in the install document with the exception of the "user" option 
for mount.
