Desire to increase the loading speed from external USB install of knoppix3.4 (2.6 option).

Understand it may be done with changes to knoppix.sh but am unfamiliar with the program changes necessary to implement the USB enable.

My system includes USB 2.0 with athlon 1900+ and a7v333 mobo.

An associated question : if knoppix.sh is changed, will the loading speed change or is it unaffected ? I would expect the operating speed after install would be at 2.0 speeds while using the external drive for knoppix live programming.

I read one post some time ago on the subject but lost its location.
