OK are you ready to BURN !? heheh
LESS THEN 10 STEP PROGRAM........
#NOTE make sure you have ide-scsi compiled into you kernel as a MODULE or
this does not work.......
the quick and easy way to tell if the module is present is type: insmod
ide-scsi and then type lsmod like so:
example of lsmod:
Module Size Used by
ide-scsi 7336 0 <--------------- this is what you want
to see.
rtl8139 12388 1 (autoclean)
nls_iso8859-1 2240 1 (autoclean)
nls_cp437 3748 1 (autoclean)
vfat 9500 1 (autoclean)
fat 31168 1 (autoclean) [vfat]
opl3 11496 0
sb 34132 0
uart401 6256 0 [sb]
sound 58264 0 [opl3 sb uart401]
soundlow 420 0 [sound]
soundcore 2692 6 [sb sound]
aic7xxx 138488 4
[root@elf rc.d]#
as you can tell i run a modular kernel for several reasons and this being one
of them.
1> install RPMS ( the easy way booo, but works fine )
a) [root@elf rc.d]# rpm -ivh cdrecord-1.8-1.i386.rpm
b) [root@elf rc.d]# rpm -ivh mkisofs-1.12b5-3.i386.rpm
#NOTE get the PPC versions.
2> vi /etc/rc.d/rc.local
add line at end like so:
------ snip for brevity -----------
fi
## call ide-scsi for cdrecording
/sbin/insmod ide-scsi
echo "Loaded ide-scsi module for Sony 8x4x32 burner"
sleep 2
[root@elf rc.d]#
3> vi /etc/conf.modules
[root@elf rc.d]# cat /etc/conf.modules

## cdrecord setup ----------------------------------
alias scd0 srmod
alias scsi_hostadpater ide-scsi
options ide-cd ignore=hdc

[root@elf rc.d]#
4>vi /etc/lilo.conf and add the cdrecord setup append.
[root@elf rc.d]# cat /etc/lilo.conf

## ------- cdrecord setup append --------
append="hdc=ide-scsi"
other=/dev/sda1
label=dos
[root@elf rc.d]#
5> run: /sbin/lilo
6> reboot or init 1
7> test dmesg for output like so:

8> check /etc/fstab and edit accordingly:
[root@elf rc.d]# cat /etc/fstab

/dev/sdb1 /boot ext2 defaults 1 2
/dev/sda1 /mnt/dos vfat defaults 0 0

/dev/cdrom1 /mnt/cdrom1 iso9660 noauto,owner,ro 0

correct you symlinks.

none /dev/pts devpts gid=5,mode=620 0 0
/dev/sdb5 swap swap defaults 0 0
[root@elf rc.d]#
9> burnsomething like:
[root@elf rc.d]# cdrecord -v speed=4 dev=1,0,0 -data LinuxPPC_2000_Full.image
in this case i just burned LinuxPPC_2000_Full.image so i have a bootable HFS
system disk for a PowerPC. works great by the way ! :)
you might need to tweak some things but this is how it is done, so get going
and burn some goodies ! :)
good luck and take care....
