Why is the boot screen blank?
So I’ve worked on several Macs over the years and I’ve never seen this before and can’t figure it out. I have a 17” PB 1.67. It works fine, but there is no boot screen or chime. It’s blank like what you would see when you have a non flashed graphics card in your Mac Pro. I’ve done all the normal resets and key combinations. I’ve even booted into open firmware and did the reset-all command which I only know worked because the Mac rebooted. Any thoughts? Something I can key into the terminal to bring back the Apple logo? I’ve erased and re-installed OS X as well. Anyone else seen or fixed this?
