Knoppix is compiled to work on x86 (32-bit) platform from i486 and up. Knoppix 4 will work on your P4 but in 32 bit. If you want a 64 bit live CD then see kanotix http://kanotix.com/info/index.php
I have intel processor 640 (3.2 GHz, 2MB Cache, 64 bit) and 945G chipset. I want to run knoppix 4. Is there any version of knoppix 4 which supports intel 64 bit processors?
