Below there are the instructions about hd install that is on CD rom.
I'm a newby ,can I have more details about each step ?
1.) initialize a free partition with the ext2 file system and mount it on
/mnt/knoppix, for example.
2.) cp -a /KNOPPIX/* /mnt/knoppix/
3.) set up /mnt/knoppix/etc/fstab and /mnt/knoppix/etc/lilo.conf for the
new system (Caution: symlinks in /boot initially point to the Ram
disk!), run lilo.
4.) mkdir /mnt/knoppix/home/knoppix && \
chown knoppix.knoppix /mnt/knoppix/home/knoppix
5.) Reboot, try the system out, fix any broken settings.

>about (1) ,what does it mean "mount a partition on /mnt/knoppix ?
> (2) copy knoppix into the directory /mnt/knoppix ? (of course not..)
> (3) ?
> (4) ?
