Well, there is good news and bad news. The good news is that if I remove this hint the machine boots with 2 CPUs. The bad news is that I get lots of: CPU0: local APIC error 0x40 CPU1: local APIC error 0x40 messages and the machine is very unresponsive. Every keystroke has a second or two of delay. It really is unusable. If memory serves I had to turn off APIC in order to see both CPUs at some time in the past. However, at some time in the past I had both CPUs and did not have the severe unresponsiveness that I get without this hint. So with APIC I get both CPUs but an unusable config. Without APIC I have one CPU but things are lively. What next? Danhome | help
