i used instructions from
http://www.knoppix.net/wiki/Hd_Based_HowTo
and pasted the iso in knoppix.37 folder.It booted fine except for the error messages about modprobe as it was searching for kernel 2.6.9 but knoppix 3.8.1 uses 2.6.11 and kde started but my usb keyboard does'nt work so i can't do anything useful. is there any onscreen keyboard utility and where do i find it. i want to do a hdinstall. is there any other away to do a hdinstall.
