OK, here goes nothing:

HOWTO: Upgrade Poor Man's Dual Boot

Step(0):
Download new ISO.
Burn new CD (with Easy CD Creator or cdrecord) and create new boot floppy (with rawrite or dd). You do not need a new boot floppy if you can boot the new CD without it. If you need a boot floppy to boot the CD, make sure you make a new kernel based boot floppy using boot.img - do not use the DOSbootfloppy. However, I strongly recommend using the faster DOSbootfloppy when you reboot, Step(8), take a look at http://www.knoppix.net/forum/viewtop...?p=12042#12042

Step(1):
Boot new CD with or without boot floppy as needed

Step(2):
mount hda1 (simply left click desktop icon for hda1)
make hda1 rw (simply right click desktop icon and click "change to rw..." and answer "yes" only if you have a VFAT hdd)

Step(3):
open a root shell (click the K cogwheel, click knoppix, click root shell)
execute steps (4)-(7) in this root shell
you could use an ordinary shell for these steps, except for step(5)

Step(4):
mkdir temp

Step(5):
mount /cdrom/KNOPPIX/boot.img temp -o loop

Step(6):
cp temp/vmlinuz /mnt/hda1/KNOPPIX
cp temp/miniroot.gz /mnt/hda1/KNOPPIX

Step(7):
cp /cdrom/KNOPPIX/KNOPPIX /mnt/hda1/KNOPPIX

Step(8)
Now reboot with your choice of kernel boot disk or the faster DOSbootdisk.
You don't need the CD anymore!

NOTE: if you created your own boot disk, then you can skip step(5) and make Step(6)
cp /mnt/floppy/vmlinuz /mnt/hda1/KNOPPIX
cp /mnt/floppy/miniroot.gz /mnt/hda1/KNOPPIX
as in the original installation

QUESTION: In Step(5) I mount boot.img to extract vmlinuz and miniroot.gz without having the rawrite or dd. Can I do this with the ISO to extract /KNOPPIX/KNOPPIX without having to burn a new CD? If I were to mount the large KNOPPIX compressed image file this way, do I need lots of extra RAM?

Enjoy!
