Knoppix 8.1 USB-stick installation

et alii.

The ntpdate package is not necessary if you have ntp.

No doubt you read in:
http://knoppix.net/wiki/Cheat_Codes#Micro-Remastering

.....
To change other boot options, look within the file 'syslinux.cfg' for the LABEL line of the way you always start with Knoppix. If you for example always use "knoppix" (and not "knoppix64") then look for "LABEL knoppix". Don't change the following KERNEL line but insert additional or change existent cheatcodes within the APPEND line.
LABEL knoppix
KERNEL linux
APPEND ramdisk_size=100000 lang=en keyboard=es xkeyboard=es apm=power-off ...

Note: If you are using Knoppix 64 bit, you have also to change the settings within '/mnt-system/boot/syslinux/syslnx32.cfg' and '/mnt-system/boot/syslinux/syslnx64.cfg'

Your /etc/ntp.conf file is the same as mine. Your problem must be elsewhere.
