Problem booting with "myconfig".

[AceX]

Hi all,

i saved my configuration to my USB falsh disk , but i didn't succeed to load the config.
at the boot screen, i typed:
knoppix myconfig=scan
and tried:
knoppix myconfig=/media/sda

and also saved to HDD,and tried and didn't suceed. and i got this error:
" Couldn't find kernel image, knoppix "

So can someone tell me how to do the booting with saved configurations ,successfully?
