Steve, Last week you wanted me to check whether just using the SMP_TIMER_NC option would work. We updated to 3.0-CURRENT 4/29/97 and built the kernel with the SMP_TIMER_NC option. When booting the system we still had the same problem with the APIC no connection stuff. After uncommenting the following defines in smptest.h the system seemed to work just fine. #define FAKE_8254_NC #define IRQ_LO_NC What additional information can we provide to you to help out in fixing this? As mentioned, the system we have is an Intel Buckeye dual processor, which I believe uses a PR440FX motherboard. Any way, I suppose this motherboard should make it onto your rogue board list.

My last changes should make this only necessary if the motherboard lies about the timer/APIC connection. The MP table I have on file for this board shows it properly declaring the missing connection, and thus the software should work without explicitly declaring it via SMP_TIMER_NC (with the latest code, this is a recent change). -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
