I seem to have some weird problem when I have 4 drives connected on a 4-way splitter ( IDEFIX in this case ) . IT boots to the point where the screen on RGB port show the red / blue / purple colors before it switches to RTG. But instead of switching to RTG it hangs on a black/white checkered ( it moves ) screen ( see picture ) . If I do a warm reboot it boots just fine and if I disconnect one drive it does a cold boot without problems.
My setup is blizzardPPC with Grex1200 and a Voodoo 4 4500.
