Copy the file /usr/local/lib/knx-hinstall to home directory:
$ cp /usr/local/lib/knx-hinstall /ramdisk/home/knoppix
Open the file using your preferred editor
Look for this part:
# remove Knoppix entry from /etc/sudoers
cp -af $TM/etc/sudoers $TR/etc/sudoers
# remove Knoppix specific menu entries (they won't work without
# sudoers entry)
chroot "$TR" rm -rf /usr/share/applnk/Knoppix /usr/share/gnome/apps/Knoppix
Comment the two lines:
# remove Knoppix entry from /etc/sudoers
#cp -af $TM/etc/sudoers $TR/etc/sudoers
# remove Knoppix specific menu entries (they won't work without
# sudoers entry)
#chroot "$TR" rm -rf /usr/share/applnk/Knoppix /usr/share/gnome/apps/Knoppix
Login as root (or open the root-shell) and execute the edited knx-hdinstall:
# /ramdisk/home/knoppix/./knx-hdinstall
