Hi,
Just started seeing what AROS is like these days after recently getting back into Amigas after years away. I'm fairly impressed.
Using Icaros 2.2.4 (after a painless upgrade from 2.2.3) on an Atom 230 (LD945GCLFS2 - believe it as an OEM only board) and find that despite the slow processor most things are quite usable.
Only real glitch I'm getting is that the GMA driver doesn't seem to like 24 bit resolutions and corrupts the screen, it is wonderful at 16 bit.
