Thanks ernst and everybody else who responded !
As I read it, I think I'll try the lite on 48x 24x 48x
CD-RW Drive which is offered by the company where I
bought this computer.
You're note on scsi made me think I'll probably need
that too - and I don't have it yet.
I did a search on "scsi emulation" but I got limited
results - one of the best is
http://www.apexdesignsllc.com/linux_6.htm but it is
SUSE specific and the line in /etc/modules.conf
"alias scsi_hostadapter off " isn't there
Can anybody provide a howto on scsi emulation in
Debian ? I'm using a 2.2.20 kernel and I hope I don't
have to compile a hole new kernel for this scsi
emulation;
I mention this as I found somebody else had probs on
it in a 2.4.18-bf2.4 kernel
(http://lists.debian.org/debian-user/2002/debian-user-200211/msg03294.html)
Thanks for any help,
Joris

Hello everybody,
I have a simple question: which cd writer do you
people recommend to buy for use with Debian (and
windows 98) ?
I'm using a 48x lite-on that usually sells for
20-30 dollars after
rebates. Works just fine except that burn proof
gets triggered when I try
to burn an audio cd at 40x, but doesn't on data at
40x. Very weird.
I use a 32x model at home.
Both work flawlessly in Linux and in Windows.
Yes, agree, I have an old 12x lite on and a newer
40x. Works fine on
both windoze and debian. I'm also useing a Plextor
48x, very nice. And a
old Sony 12x and a Teac scsi 12x, also very nice.
I'm useing scsi emulation on everything exept for
the Teac ofcourse:) .
The good ting about scsi emu is that when you have a
burner and a cd/dvd
you are able to copy cd's "on the fly".
Good luck.

Hi,
a good thing for a start is google and "scsi emulation HOWTO".
But, it's not that hard to get up and running, I have it on both 2.2
and 2.4 kernels. First you need some modules:
sg
sr_mod and
ide-scsi
(My hardware on this box is:
hdb: Pioneer DVD-ROM ATAPIModel DVD-106S 012, ATAPI CD/DVD-ROM drive
hdc: PLEXTOR CD-R PX-W4012A, ATAPI CD/DVD-ROM drive
and I have resently upgraded my 2.2 kernel to 2.4.20)
Now let say you have a burner and a cd/dvd. > hdb and hdc.
First change the link to /cdrom to be a pointer like this:
lrwxrwxrwx 1 root root 4 Mar 4 17:23 /dev/cdrom -> scd0
and so your burner will be > scd1
If you run cdrecord -scanbus you will see something like:
draupner:~# cdrecord -scanbus
Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
Linux sg driver version: 3.1.24

If not, you might need som options added to either /etc/lilo.conf or
/etc/modules.conf, or mabye both.
In my lilo.conf I got:
image=/vmlinuz
append="hdb=ide-scsi hdc=ide-scsi"
label=Debian
read-only
For this to work I think you'll need a reboot.
And if you need to add options to /etc/modules.conf you can try with:
options ide-cd ignore=hdc # tell the ide-cd module to
ignore hdc burner
options ide-cd ignore=hdb # cdrom
alias scd0 sr_mod # load sr_mod upon access of scd0
alias scd1 sr_mod
#pre-install ide-scsi modprobe imm # uncomment for some ZIP
drives only
pre-install sg modprobe ide-scsi # load ide-scsi before sg
pre-install sr_mod modprobe ide-scsi # load ide-scsi before sr_mod
pre-install ide-scsi modprobe ide-cd # load ide-cd before ide-scsi
Try this, and good luck:)
