Other Help Topics :: ReMastering HOWTO for DSL



Hello guys!

I just made a remaster of DSL 3.4 and it works like a charm. Thanks to Robert for making bcrypt a part of the original DSL. That saves me from compiling it into the remaster (or using the extension).

Keep on having fun with DSL,

REMASTERED dsl-*-syslinux.iso WON'T BOOT ON SOME BIOS (?)

Having some antique machines, I decided to investigate the syslinux version.
As dowmloaded, dsl-3.4-syslinux.iso (and dsl-3.3-syslinux.iso) booted up nicely :)
(both as a live CD and with the ISO image running in VMware Player)

... so I want to remaster the ISO to include extension files, but the re-master won't boot in this machine (Gigabyte GA-6VXE7+ motherboard), whether as a CD or in VMware Player.
The re-mastered live CD gets as far as displaying:-

1. FD 1.44MB System Type-(00)
_                  (<- blinking cursor, no keyboard input possible)

Yet in an older AOpen AX6B system, the re-mastered CD boots up perfectly, both as a live CD and in VMware Player  :)

I'm generating the ISO with the command given in this forum (shown with the resulting messages) :

# mkisofs -r -J -b KNOPPIX/boot.img -c KNOPPIX/boot.cat -o myknoppix.iso newcd
I: -input-charset not specified, using utf-8 (detected in locale settings)
Size of boot image is 2880 sectors -> Emulating a 1440 kB floppy

To minimise variability in the investigation the files in newcd are exactly as unpacked from the downloaded ISO - no additions or changes.
BTW the GA-6VXE7+ , which is my main machine, has never had any problem with booting re-mastered isolinux versions.

Has anybody else come across this sort of problem ?
Hello JohnnyH!

I'm sorry that I adress your problem after such a long time but I've had my hands full so to speak. I think the problem lies in making the iso-file the wrong way. I think this would be the right way to go about it:
#mkisofs –no-pad –l –r –J –no-emul-boot –boot-load-size 4 –boot-info-table –b boot/isolinux/isolinux.bin –c boot/isolinux/boot.cat –hide-rr-moved –o mydsl.iso newcd

This you can find on page 56 in this thread.

Have fun remastering,

Hi meo, thanks for your reply :)
The mkisofs statement that you give above is for the 'normal' (isolinux) version, but in this case I was using the syslinux version, and the appropriate mkisofs statement for that. The strange thing is that it booted OK on one machine and not the other (all my machines boot the isolinux version OK)  ???
So I guess it can be designated as a BIOS compatibility issue FWIW  :D
Hello guys!

I just made a remaster of DSL 4.0 rc3 and it works just fine. I will get back to you with the complete HOWTO as soon as I can.

Have fun out there in cyberspace,
meo
