I have a 4.4.10 hard drive DSL working decently on an old HP Omnibook 6000 (Pentium III) with 256M of RAM.
I use a WiFi key from Hamlet, HNWU254G_RTL that works also nice. I struggled a little bit to have it working because I am not a linux expert. I am also using a USB port extension from Hamlet and a wireless mouse from Trust that get recognised easily. I did some configuration work on that installation that I like.
I would like to try 4.11RC2.
Is it possible to upgrade without loosing the current configuration or I will need to start from the scratch?
