Mon Nov 4 17:08:47 UTC 2013 Slackware 14.1 x86_64 stable is released! It's been another interesting release cycle here at Slackware bringing new features like support for UEFI machines, updated compilers and development tools, the switch from MySQL to MariaDB, and many more improvements throughout the system. Thanks to the team, the upstream developers, the dedicated Slackware community, and everyone else who pitched in to help make this release a reality. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. Have fun! :-)

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 \
|
|
-eltorito-alt-boot -no-emul-boot -eltorito-platform 0xEF \
|
|
-eltorito-boot isolinux/efiboot.img \
|
|
-m 'source' \
|
|
-V "SlackDVD" .
|
|
|
|
As an additional step, the ISO image may be processed to make it bootable
|
|
when written to a USB stick. This processing will not impact the ISO's
|
|
ability to boot from DVD media. Use the following command to do this:
|
|
|
|
isohybrid -u /tmp/slackware-dvd.iso
|
|
|
|
On my system, here's the command I'd use to burn the resulting DVD ISO:
|
|
|
|
growisofs -speed=2 -dvd-compat -Z /dev/sr0=slackware-dvd.iso
|
|
|
|
If your burner is not /dev/sr0, 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.
|
|
|
|
To write the ISO image to a USB stick (process with isohybrid first, as
|
|
shown above), use a command such as this (replace /dev/sdX with the device
|
|
name for your USB stick):
|
|
|
|
dd if=/tmp/slackware-dvd.iso of=/dev/sdX bs=1M
|
|
|
|
Or, you can burn directly from the Slackware tree to a DVD(-/+)R(W):
|
|
|
|
growisofs \
|
|
-Z /dev/sr0 \
|
|
-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 \
|
|
-eltorito-alt-boot -no-emul-boot -eltorito-platform 0xEF \
|
|
-eltorito-boot isolinux/efiboot.img \
|
|
-m 'source' \
|
|
-dvd-compat \
|
|
-V "SlackDVD" .
|
|
|
|
Note that the source code directory will not be included on these DVD
|
|
images in order to keep them under the limit for a single-layer disc.
|
|
If you are using double layer DVD media and want to burn the complete
|
|
tree to your disc, remove the -m option line from the command.
|
|
|
|
|
|
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 \
|
|
-eltorito-alt-boot -no-emul-boot -eltorito-platform 0xEF \
|
|
-eltorito-boot isolinux/efiboot.img \
|
|
-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 \
|
|
-eltorito-alt-boot -no-emul-boot -eltorito-platform 0xEF \
|
|
-eltorito-boot isolinux/efiboot.img \
|
|
-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!
