Thanks for your quick reply.

I will have a look into that voodoohda.

The graphics flickering is very minor. Over some shades of purple/blue on selected items.
The USB issue is USB drives not mounting sometimes. I don't have any options in my lame HP bios :/.

I will also attempt to get LAN working in 32bit mode.

The main thing I need though is to get my wifi working.

I'll experiment and report back as soon as I have some new results.
