Well, as I can see from the scenario, your CDRW is getting detected as a SCSI drive. In fact, it is an IDE drive - am I right??

To get around with the problem, just remove the "append=...." line from lilo.conf 'coz you don't need it. Then update lilo using /sbin/lilo. The next time you boot into linux your CDRW should be detected as an ordinary IDE CDROM. But then, you won't be able to write CDs through linux, 'coz all the CD- Writing softwares in linux (including cdrecord and Xcdroast) need your drive to be SCSI.

Now, to make your IDE CDRW (now detected as an IDE CDROM) work for writing CDs, what you can use is an emulation driver - ide-scsi. This is precisely what you've been seeing in your lilo.conf. This is a modular driver which can be used using modprobe or insmod. The advantage is - install when you want, uninstall after using it. I guess, you know how to uninstall / remove modules.

When you add this driver, just check out the working of the driver using #cdrecord -scanbus

If you get the output saying the HOST/DEVICE/LUN ids, then you can be pretty sure that the driver will work for you. The only problem I faced was that the normal IDE-CD emulation driver used to interfere with it. So, to be on a safer side, make sure that you remove ide-cd before inserting ide-scsi. The ide-scsi driver is available online or can be found at PCQ's wesite (in fact, it comes built into PCQ Linux Distro).

After you're done with the CDRW for writing, remove the ide-scsi driver using #rmmod sg #rmmod ide-scsi

These are dependant modules.

Then insert the usual ide-cd driver using #modprobe ide-cd

And you'll be back with your CDRW as IDE CDROM.

My CDROm drive Samsung CD writer RW 8.4.32 is recognised by the kernel, but when i try to mount the CDROm, I get a message /dev/cdrom improper device or device does not exist. I have the following line in lilo.conf append="hdc=ide-scsi" This used to work and still works on Caldera with kernel 2.4.2 (PCQuest CD's)loaded in another partition.

the append line in your lilo.conf means that scsi emulation is used for your drive(cd burning programs require it). try mounting /dev/scd0 as your cdrom drive..
