you don't need the scsi-modules to write a cd if you have an atapi cd writer then do the following

cdrecord dev=ATAPI:0,1,0 -checkdrive

the 0,1,0 can be something else according to your settings,

i get the following if i do this

then i start

gcombust

and the go to Burn and change the following settings below

Device: ATAPI:0,1,0
Driver: mmc_cdr

you can know what drive driver to use when u do the cdrecord stuff

ATAPI burning

To add a tip for those more console oriented:

I found it useful to make a script that I use for burning iso files created with mkisofs:

#!/bin/bash
cdrecord dev=ATAPI:0,0,0 driveropts=burnfree speed=12 -v -data $*

Put this in your path (/usr/local/bin, perhaps) and you can call it, for example, with "burn-image myimage.iso". It saves alot of time for typing all the options, but is completely unneccessary if you are using gcombust as instructed (and encouraged) above.

Yes, you need no scsi emulation and no grub modifications anymore. I have both K3b and Xcdroast working. K3b is very nice, but I can't dup cd's with it yet on my laptop since it only has one drive. I have to use Xcdroast for that.

I haven't noticed any problems with speed. However, my laptop has a combo DVD/CDRW drive which is pretty slow to begin with. It's pretty easy to setup SCSI emulation so if that's already working, just go with it. For a new setup, I'd try ATAPI burning first though. I'm a firm believer in, "if it ain't broke, don't fix it."

The reason I started experimenting with ATAPI was that I had a problem with my burner where it would not read audio CDs well through SCSI emulation. By removing SCSI and going to straight ATAPI. it fixed it right up.

I would be interested in some comparisons between burning speed if anyone can supply them.

K3b detects my ATAPI DVD/CDRW and writes to it perfectly. No configuration was necessary. I had problems with .8.1, but .9 is running great!

xcdroast auto-detected and configured my ATAPI burner without issue, and in my opinion has a cleaner interface than gcombust. xcdroast also includes a wrapper that allows non-rooted users to burn CDs, which is quite nice.
