Try just disabling apic: hint.apic.0.disable="1" > I can get to the installation screen by booting in "safe mode." Is it okay to > install from there? In the kernel config file, it seems APIC is associated > with SMP. I'm running UP, so why would this have any affect on my system? Newer machines have APIC support which gives faster interrupts. But it's quite safe to run a UP or MP machine with apic disabled. You just lose performance (or the extra processors). -- Nate
