Hi folks,

Well, I'm sure this must be documented somewhere, but I can't seem to
find it on google. The problem is simple. I've got an IDE cd burner,
so I need to use the ide_scsi modules.

1) They don't seem to get loaded properly so I have to load them
manually before burning
2) They don't unload when I need to do things like mount a cdrom w/
filesystem or play and audio cd. So I have to unload them and reload
the regular ide-cdrom modules.

Is there a way to solve this? The users in my lab will have a really
hard time burning CDs and such with this problem ... as they of course
don't have root access.

Thanks all,

Dave Topper

What distribution are you using?

Why not just use the ide-scsi driver all the time, then access the device
at /dev/scd0? As for allowing non-root users to mount data CDs, play
audio CDs, or burn CDs, that varies slightly per distribution. Ditto for
making sure ide-scsi gets loaded when needed.

The ide-scsi emulation mode is not needed any more. Take a new kernel and a
new version of cdrecord, mkisofs and cdrdao. Kick ide-scsi and get
dma-support instead.

Hi,
I am using an IDE CD-ROM burner under Debian.
The modules I use are the sg and ide_scsi modules.
You can auto load them by placing the module names in /etc/modules
In /dev, my cdrom is a symlink to the scd0 device, so I never need to
use the cdrom as an IDE device.

I also have used append="hdx=ide-scsi" (replace hdx with the proper ide
device: probably hdb, hdc, or hdd)

also you remove a module stack with modprobe -r module
and sometimes modprobe -q iwll load stubborn modules.
check the manpage :-)
I hope this is a little helpful.
