Version 2 of the sm501 changes with fixes that are needed to get AmigaOS 4.1FE to boot and able to produce graphics.
The strange blue-white colors that first appear are actually correct and because of AmigaOS selecting a low resolution PAL mode by default instead of a board specific mode. To work around this one can select the last option to boot the live CD and then select a better board specific mode from ScreenMode Prefs. It takes a while for the ScreenMode window to appear and graphics operations are slow which could use some improvement but at least it seems to work correctly now apart from some unimplemented drawing modes for compositing. If this could be merged before the freeze with the sam460ex patches and Sebastian's ehci patch then QEMU 3.0 could be the first version that can boot AmigaOS.
