+HOW TO MAKE A BOOTABLE SLACKWARE DVD ISO IMAGE
+
+To make a bootable Slackware install DVD, get into the top level Slackware
+directory (The one with ChangeLog.txt in it) and issue a command like this
+to build the ISO image in /tmp:
+
+mkisofs -o /tmp/slackware-dvd.iso \
+ -R -J -A "Slackware Install" \
+ -hide-rr-moved \
+ -v -d -N \
+ -no-emul-boot -boot-load-size 4 -boot-info-table \
+ -sort isolinux/iso.sort \
+ -b isolinux/isolinux.bin \
+ -c isolinux/isolinux.boot \
+ -V "SlackDVD" .
+
+On my system, here's the command I'd use to burn the resulting DVD ISO:
+
+growisofs -speed=2 -dvd-compat -Z /dev/dvd=slackware-dvd.iso
+
+If your burner is not /dev/dvd, replace the device with the one your
+system uses.
+
+I find discs burned at 2x are more reliable than ones burned at higher
+speeds, but you may see completely different results depending on media
+and burner type. The -dvd-compat option is also used so that a complete
+lead-out is written to the media for maximum compatibility.
+
+Or, you can burn directly from the Slackware tree to a DVD(-/+)R(W):
+
+growisofs \
+ -Z /dev/dvd \
+ -R -J -A "Slackware Install" \
+ -hide-rr-moved \
+ -v -d -N \
+ -no-emul-boot -boot-load-size 4 -boot-info-table \
+ -sort isolinux/iso.sort \
+ -b isolinux/isolinux.bin \
+ -c isolinux/isolinux.boot \
+ -dvd-compat \
+ -V "SlackDVD" .
+
+
+HOW TO MAKE A SET OF BOOTABLE / INSTALLABLE CDROMS
+
+This is a little bit more tricky. Step one will be to split the tree into
+portions that will fit on the media that you plan to burn to. The first
+disc must contain these directories:
+
+/isolinux/
+/kernels/
+/slackware/
+
+You'll need to make other /slackware/ directories on discs 2, 3, and maybe
+more, moving some of the disc series from disc 1 to other discs to make
+things fit. It is also possible to split a series to make more efficient
+use of the CD media. See the README_SPLIT.TXT example and instructional
+file in this directory for details about how to set that up.
+
+The rest of the splitting up of discs is left as an exercise for the reader.
+
+To make the first (bootable) ISO, a command like this is used within the
+directory where the disc tree is. Let's say the directory is 'd1' and you
+wish to output the ISO image in /tmp:
+
+cd d1
+mkisofs -o /tmp/slackware-install-1.iso \
+ -R -J -A "Slackware Install 1" \
+ -hide-rr-moved \
+ -v -d -N \
+ -no-emul-boot -boot-load-size 4 -boot-info-table \
+ -sort isolinux/iso.sort \
+ -b isolinux/isolinux.bin \
+ -c isolinux/isolinux.boot \
+ -V "SlackCD1" .
+
+Making a non-bootable disc is similar. Just omit a few options:
+
+cd d2
+mkisofs -o /tmp/slackware-install-2.iso \
+ -R -J -A "Slackware Install 2" \
+ -hide-rr-moved \
+ -v -d -N \
+ -V "SlackCD2" .
+
+To burn an ISO image to CD-R(W), the cdrecord command is used. For complete
+instructions, see the man page ('man cdrecord'). On my own machine where
+the burner is /dev/cdrw, disc one would be burned with the following command:
+
+cat /tmp/slackware-install-1.iso | cdrecord -v dev=/dev/cdrw speed=10 fs=8m -tao -eject -data -
+
+As before, it's possible to burn from the disc trees without the intermediate
+step of creating iso images by omitting the -o option to mkisofs and piping
+the output directly to cdrecord:
+
+cd d1
+mkisofs \
+ -R -J -A "Slackware Install 1" \
+ -hide-rr-moved \
+ -v -d -N \
+ -no-emul-boot -boot-load-size 4 -boot-info-table \
+ -sort isolinux/iso.sort \
+ -b isolinux/isolinux.bin \
+ -c isolinux/isolinux.boot \
+ -V "SlackCD1" . | cdrecord -v dev=/dev/cdrw speed=10 fs=8m -tao -eject -data -
+

+
+NOTES:
+ The isolinux/isolinux.boot file will be created on the disc; it's not
+ supposed to be in the source tree. I mention this only because so many
+ people report the "missing" isolinux/isolinux.boot file as a bug.
+
+ The "-boot-load-size 4" is actually not large enough to hold the isolinux
+ boot loader, but many BIOS implementations are broken and will *only*
+ accept "4". Evidently many newer, more correct BIOS implementations
+ expect this and will continue to load the boot loader file until the
+ EOF is reached. Anyway, previous uses of larger values were correct, but
+ led to the Slackware ISO not booting on some machines which contained
+ broken BIOS implementations. It is my hope that by using the incorrect
+ value of 4 sectors that the ISO will boot on most (if not all) machines
+ that are supposed to be able to boot from an ISO image.
+
+ I don't know how to create a bootable Slackware ISO on operating systems
+ other than Linux, but it should be easy to burn the Linux-created ISO with
+ most CD burning software on any operating system.
+
+Enjoy!
+
+ -P.
