Kernel Set-up
Most of the following needs to be done as root.
Make sure that the cdrecord, cdparanoia, mkisofs RPMs are installed.
You need to make sure that the IDE-SCSI device interface is being used
for the CD-R.
RedHat 7.X will automatically configure your system correctly, if you
have the CD-RW drive installed when RedHat Linux is being installed.
Test and Add "insmod ide-scsi" to /etc/rc.d/rc.local .
View the kernel modules list with "lsmod".
Will need to change the boot parameters by adding the following line
to /etc/lilo.conf where /dev/hdb is my CD-RW:
append = "hdb=ide-scsi"
This is my /etc/lilo.conf:
boot = /dev/hda
timeout = 250
linear
prompt
default = linux
vga = normal
read-only
# can't set mem=128M since BIOS uses 8M for video memory
append = "mem=120M hdb=ide-scsi"
map=/boot/map
install=/boot/boot.b
image = /boot/vmlinuz-2.2.14-5.0
label = linux
root = /dev/hda1
Run "lilo" to instantiate the new lilo.conf.
Reboot. Test that the ide-scsi is working with "cdrecord -scanbus"
Prepare an ISO9660 Image
Now you are ready to create an ISO9660 image file.
Put all the files to be saved in a directory (e.g. /dir/path).
Also before creating the image file, make the file .mkisofsrc
and edit it with your own values and place in the dir you are
running from.
Run the command to create the image file:
mkisofs -v -J -r -d -D -f -l -L -N -o /tmp/xxx.iso /dir/path/
ISO9660 Image Configuration File
The following is an example of the mkisofs configuration file,
and the more common entries with explanations.
#
# command: mkisofs -v -J -r -d -D -f -l -L -N -o /tmp/xxx.iso cdrom/
#
#CONFIGURATION
# mkisofs looks for the .mkisofsrc file, first in the cur-
# rent working directory, then in the user's home directory,
# and then in the directory in which the mkisofs binary is
# stored. This file is assumed to contain a series of lines
# of the form TAG=value, and in this way you can specify
# certain options. The case of the tag is not significant.
# Some fields in the volume header are not settable on the
# command line, but can be altered through this facility.
# Comments may be placed in this file, using lines which
# start with a hash (#) character.
#
# APPI The application identifier should describe the
# application that will be on the disc. There is
# space on the disc for 128 characters of informa-
# tion. May be overridden using the -A command line
# option.
APPI=R.K.Owen /usr/src/ collection 2000-02-17
#
# COPY The copyright information, often the name of a file
# on the disc containing the copyright notice. There
# is space in the disc for 37 characters of informa-
# tion. May be overridden using the -copyright com-
# mand line option.
COPY=check individual packages
#
# ABST The abstract information, often the name of a file
# on the disc containing an abstract. There is space
# in the disc for 37 characters of information. May
# be overridden using the -abstract command line
# option.
#
# BIBL The bibliographic information, often the name of a
# file on the disc containing a bibliography. There
# is space in the disc for 37 characters of informa-
# tion. May be overridden using the -bilio command
# line option.
#
# PREP This should describe the preparer of the CDROM,
# usually with a mailing address and phone number.
# There is space on the disc for 128 characters of
# information. May be overridden using the -p com-
# mand line option.
PREP=R.K. Owen, Ph.D.
#
# PUBL This should describe the publisher of the CDROM,
# usually with a mailing address and phone number.
# There is space on the disc for 128 characters of
# information. May be overridden using the -P com-
# mand line option.
PUBL=KooZ Software
#
# SYSI The System Identifier. There is space on the disc
# for 32 characters of information. May be overrid-
# den using the -sysid command line option.
SYSI=RKOwen /usr/src/ 2000-02-17
#
# VOLI The Volume Identifier. There is space on the disc
# for 32 characters of information. May be overrid-
# den using the -V command line option.
VOLI=RKOwen-src-2000-02-17
#
# VOLS The Volume Set Name. There is space on the disc
# for 128 characters of information. May be overrid-
# den using the -volset command line option.
#
Test the ISO9660 Image
To test out the image file, mount it via the loopback device
mount -t iso9660 xxx.iso /mnt/image -o loop
Where /mnt/image is a mount point created for this purpose.
The ISO9660 image can be perused like an ordinary filesystem.
When finished then unmount the image filesystem with
umount /mnt/image
Test Burn the Image
Now that an image is ready, it can be burned into a CD.
Run several tests with
cdrecord -v -eject -dummy [-multi] speed=4 dev=0,0,0 xxx.iso
The device numbers can be found from cdrecord -scanbus .
The -eject will cause the CD tray to slide out after the burn,
which is useful to signal when completed, and some versions of Linux
will try to automount the burned CD when completed unless it's ejected.
(Use -multi if you plan to add more to the CD later and the speed and
dev are appropriate for your CD-RW - mine is rated at 8x8x32 and
as you can see I back it off one level.)
When you are satisfied with the results then remove the "-dummy" option.
Ubuntu changes
Ubuntu has made some changes, which changes things a bit.
Look in /etc/cdrecord/cdrecord to see the default name
(e.g. /dev/cdrw which is a symbolic link to /dev/hdb
for example.) Therefore, it looks like one of the changes is using
the IDE (ATA) interface instead of the SCSI layer. Hence, no need
to specify the device or speed if the defaults are defined correctly.
cdrecord -v -eject -dummy [-multi] xxx.iso
Check if things are working with cdrecord -inq to see if things
look reasonable.
Multi-session CDs
If doing multi-session CDs, make sure you read the README provided
with cdrecord.
You will need to get the start track with
cdrecord -msinfo dev=0,0,0
and use the value in mkisofs (e.g. 0,53151)
mkisofs ... -o yyy.iso -C 0,53151 -M /dev/cdrw /dir/path
Also you will need to carefully structure the dir path.
You can add directories, but not overwrite existing files or
dirs on the CD.
