Hi Guys, I've got a Mac Pro 1,1 with upgraded CPUs (dual quad 2.66) and a 3870 graphics card for now. When I want to game I just swap out my 3870 for a 4890, take out my 3 OSx drives and put another drive into the first bay with W7 on it. Now since setting this up I've been getting a weird problem while going back to OSx - once I turn the pro on, it doesn't chime and goes to a blank white screen. If I hold down Alt at the right time then I can select my boot disk and it boots up all fine. If I don't then it stays white and refuses to boot. Now I'm in the process of buying a 6XXX series card for use with Cindori's drivers (thanks again for the PM buddy) and I wont have the boot screen to know when to hold down Alt. Any ideas from you geniuses? Thanks!
