OK. I got to the desktop. It seemed to freeze at the selection window for startxfce4, start in vesa mode etc. but it got to the desktop.
There was no wallpaper, just a blue background, but i right clicked on the desktop and selected my wallpaper. Internet is working. But I'm on the root account.
These are the steps I took:
On boot up I selected boot as single user.
Then at the command prompt I did the command recommended by ASX - kldload i915kms This changed the screen resolution to a much sharper resolution
Then I did - echo "startxfce4" > ~/.xinitrc
Then I got to the select startxfce4 screen and selected startxfce4. It seemed to be frozen it took a long time to get to the desktop but I'm here.
I'll try installing the system now.
