The first CD actually gives a choice when starting the install, of idepci, 
compact, vanilla or bf24, IIRC.   But they don't seem to be in deb package 
form.

Just, nothing's stopped working.   :)

I'll investigate getting X-cd-roast (and cdrecord) working now.   ('Now' 
being a couple of days later...)  

Well now, lsmod, modprobe and insmod tell me that  ide-scsi and  sg  are 
present, but  sr_mod isn't:

lsmod

sg                     14928   0  (unused)

# insmod sr_mod
insmod: sr_mod: no module by that name found

And it isn't in any subdirectory of /lib/modules/2.2.20  either

cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
cdrecord: No such file or directory. Cannot open SCSI driver.


I've got /dev/cdrom symlinked to scd0
alti:/dev# ls -l cdrom
lrwxrwxrwx    1 root     root            4 Jul 11 00:13 cdrom -> scd0

My /etc/fstab says 
/dev/cdrom      /cdrom          iso9660 ro,user,noauto          0       0

And my Grub  /boot/grub/menu.lst file says 
title           Debian GNU/Linux, kernel 2.2.20
root            (hd0,0)
kernel          /vmlinuz-2.2.20 root=/dev/hda5 hdb=ide-scsi ro
savedefault

I can still mount the cd-rom as a IDE device:

alti:/# mount -t iso9660 /dev/hdb /cdrom
mount: block device /dev/hdb is write-protected, mounting read-only

but NOT as a SCSI one:

alti:/# mount -t iso9660 /dev/scd0 /cdrom
mount: the kernel does not recognize /dev/scd0 as a block device
       (maybe `insmod driver'?)

I suppose this means I need sr_mod?   I'm a little surprised the 'vanilla' 
kernel doesn't have it already, since it has sg and ide-scsi.    But I can't 
find sr_mod anywhere.

Searching  www.debian.org  for   sr_mod  lists it in kernels  2.4.16 and 
2.4.18 (but no 2.2.nn kernels).    (I assume this means the 2.2.20 kernel (as 
shipped with Woody) definitely doesn't include sr_mod?)

I assume I *could* download and install a 2.4.16 or 2.4.18 kernel, but would 
this cause conflicts with all the stuff I already have installed?    I'd 
rather just download the sr_mod module from somewhere (if I could find it!)  
and install it with insmod than download a 8MB kernel image file.....   

Sorry for these elementary questions, but I've never messed around with 
kernels before.
