The SuSE boot images are for CD/DVDs which boot up just like the SuSE
distro CD/DVD, except that they do not contain installation RPMs, etc.
They work great for doing network installs, booting into an installed 
system, and Rescue mode.

Note that at least some of the images here are not the full media
capacity.  Since you need to download and burn less data, these
are faster than full-capacity images filled out with useless bytes.
This strategy may or may not cause portability problems with older
CDROMs, etc.

I have tested writing the suse10.0boot64cd.image from the Linux
command line and with k3b, specifically making sure that the resultant
CD copy is bootable.  With k3b, just use "Write CD Image" and use all 
default settings.  This works for me on my command-line:

    cdrecord dev=/dev/dvd speed=48 gracetime=2 -dao driveropts=burnfree -eject -data suse10.0boot64cd.iso

Set the speed number to the X value of your CD writer (for the type
of CD that you are using: CD-R, CD+RW, etc.).  Set the final filepath 
to specify the image file that you have downloaded.  Set /dev/dvd to
a device file (or sym link) for your CD writer.
