Greetings -- I am somewhat new to Linux, so I apologize if my question comes across as simplistic.

I want to use Knoppix as an alternate-boot OS on a company Windows machine, and I have successfully installed Knoppix 6.1 on a USB key. Each time I boot up, the system asks how much I want to set aside for my personal customization - which I presume is the same as using a persistent image.

I specify a value, but then I never see the system write any of my customizations (e.g. screen resolution) to the USB key.

When I boot form the USB key do I need to enter any command line options to properly create the space for the customized install and then save to this image?

Thanks in advance.
