recently, i hv download the knoppix 3.3...

My notebook is P4 1.4, 256DDR, 24x CD-rom, and winXP installed.

so, i follow the instructions, goto bios setup and select boot on cd-rom.
After that, i put in the knoppix live cd... the following are two method i've tried to boot the knoppix...

if i made the cd-rom boot first:
nothing was happed, the cd-rom did run for a minute it seem like something was working behind, but suddenly... it automatically load the windows just like nothing was happened.

if i disable the floppy and hd except cd-rom and cd-rom boot first:
a message told me tat it was an invalid system disk, put an valid one and press enter (the message is something like tat).

I just can't boot the knoppix... what is the problem?

thx a lot...
