I while ago I fell foul of all sorts of problems when I tried to install Haiku on some bits of hardware I had to hand. Several people, slightly uncharitably, took me to task over my choices of hardware. I suggested at the time that it might not be a bad idea (cough) if Haiku published on the Haiku web page a list of hardware that Haiku was known to install on and boot without the requirement of an external boot disk.
I wonder if such a list might be forthcoming soon?
