is it possible to install rpm packets in knoppix if it is then how can i do it.
Use alien to make the rpm into a .deb (alien -d <rpm>) then install as normal (dpkg -i <pkg>).
See man alien.
how can i make the windisk to mount when starting knoppix automatically
Edit your /etc/fstab file. Each mount has an entry; the 'noauto' means not mount at boot so change it to 'auto'. You will then probably have to boot with the bootcode 'nofstab' to prevent Knoppix from replacing your fstab with the default one at each boot. If you are running from CD or from a 'toHD' install you will have to save your config setup using the script provided under the Knoppix menu item and boot with the 'myconfig=scan' bootcode.
