Hi Steven,

meanwhile I have read the CD-Writing HOWTO. Everything seems
quite easy and logical under Linux, apart from one thing: the
hardware support. I have a rather new CDRW drive connected to IDE.
It works under Windows with Nero 5.5. I would like to get rid of
Windows on that machine - as soon as possible.

This is the very section I was quoting from.

The problem is that for cdrecord, the IDE drive has to be emulated as
SCSI. I found the mentioned driver modules in Slackware and
installed them with:

 insmod ide-cd
 insmod ide-scsi
 insmod scsi_mod
 insmod sg
 insmod sr_mod
 insmod loop
 insmod iso9660

But it seems not to be enough to install the drivers, as the kernel
contains IDE support and by default recognizes the CDRW
drive as /dev/hdc. The suggested fix is to edit lilo.conf:

--------------- from CD write HOWTO -------------------

  ... The device file name
  representing your CD-Writer has to be passed to the driver in the
  Linux kernel. Example: hdb=ide-scsi.  Such a setting should be added
  to lilo.conf or chos.conf if the driver is statically compiled into
----------------------------------------------------------

The changes in lilo.conf according to the HOWTO:

--------------- from CD write HOWTO -------------------

       image=/boot/zImage-2.2.14
         label=Linux
         read-only
         append="hdb=ide-scsi"

       linux "Linux 2.1.14" {
               image=/boot/zImage-2.0.37
               cmdline= root=/dev/hda5 readonly hdb=ide-scsi
       }

If the driver for IDE/ATAPI CD-ROMs is loaded as a module, then the
above won't make any difference to you, but make sure you include the
options-line from the next listing. The last three lines of that
listing are generally suggested to further automate the loading of the
required modules.

options ide-cd ignore=hdb      # tell the ide-cd module to ignore hdb
alias scd0 sr_mod              # load sr_mod upon access of scd0
#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

-----------------------------------------

The last commands are probably corresponding to what I use to do with
insmod? Is there an alternative for 'options' and 'alias' lines
without using lilo.conf.

There is a very minimalized lilo packet for BL 1.x. Do you think that
this would be compatible with Slackware 7.1 if I want to test the
suggested emulation?
