Gtk2 :: GTK2 mydsl troubble

hy comunity,
i may need some help on gt2-07....dsl.
if try to download it on embedded ver. of DSL, it may do, or not.
just to momentary flavor of machine.

if i try to boot from CD DSL2.0 it absolutely does not WORK!
it says right at the end of download : Please mount optional Dir. first

its realy anoing to try many times, always with no success,
just to find out, that this is needed, to run
gambas.dsl.
is there anyone, who can give a newbee in linux and dsl
a CLEAR instruction how to get this GAMBAS on DSL running?

thnx in advance,
tracer

thnx for so much reply.
will take som time to understand tem all
