yes, red, blue then purple screens on aga are obviously some kind of os4 boot messages. what i observed is that os4 freezes sometimes on reboot with the purple screen if i havnt hold the keys for long enough. it doesnt seem to get past this point on boot also if i have deneb flash enabled, probably because of the modified rom-image it contains, but im not sure on that.
i would advice to turn off the flash on deneb to test if u have experiencing probs.
