As we assume that you have a working CD-writer on your system, and you know how to use it, we wont go into much detail about burning the CD. If you are burning your CD on a Linux system, you can install the excellent XCDroast package. In XCDRoast, switch on the Rock Ridge extensions, and the creation of a TRANS.TBL file.
Make sure the top directory of the CD contains at least the following files and directories:
COPYING RPM-PGP-KEY README RedHat/
The following directories might come in handy:
doc/ gnome/ misc/ dosutils/ images/
Since XCDroast doesn't support creation of bootable disks you'll need to
use other tools, for example
mkisofs
(
RPMs). and
cdrecord. (
RPMs).
You'll need to create an image file which will be written to the CD. This
file will be 500Mb or more so find a partition with enough free space and
change the path for redhat.img in the following commands if
necessary. You may need to be root to use mount and cdrecord.
Change directory to the place in your mirror that will be the root directory of the cd. For instance, redhat-6.1/i386.
mkisofs -v -r -T -J -V "Red Hat 6.1" -b images/boot.img -c boot.catalog -o /tmp/redhat.img .
The file ${RHROOT}/boot.catalog will be created by
mkisofs.
Some versions of mkisofs do not have a -J option. It can be
omitted since the Joliet extensions it specifies are not used by the
installer although they make the CD more readable in Windows.
If you're paranoid you can test your new disk image by mounting it. If you forgot to fix the file permissions or set the rock ridge extensions then the error will be obvious here since the file names and directory structure will be wrong.
mount -t iso9660 -o ro,loop=/dev/loop0 /tmp/redhat.img /mnt/cdrom
When you're done, don't forget to unmount it.
umount /mnt/cdrom
Be sure to set the correct speed for your device. This command is for a 4X CDR. You may have a 1X or 2X drive.
cdrecord -v speed=4 dev=0,3 /tmp/redhat.img
In the above command, it is assumed that the CD writer is on SCSI bus 0, with ID number 3.
