Sony says I must, among other things, uninstall Intel Application Accelerator (IAA) on my Dell 8250 before installing firmware, then upon reboot, IAA will reinstall automatically. Dell says don't do this, that it could ruin my computer and won't tell me how. So I'm using DRU-500AX without firmware and so far no problems. BUT, does anyone have instructions for how to uninstall IAA on Dell? And will it really reinstall upon reboot automatically without causing problems? I need specific, detailed instructions and not general ideas. HELP PLEASE. Someone must have a Dell 8200 series AND a Sony DRU-500A or AX.
