Thanks for clearing up the confusion regarding optional SMP kernel paramaters. Unfortunately, my 3500 with dual PIII 733's still fails to boot if I compile the kernel with "options SMP" and "options APIC_IO." Is there anything out of the ordinary that must be done to make SMP work with the Netfinity 3500 M20's? Is it possible to step through the kernel boot procedure to determine what exactly is causing the machine to stop? Or, is there any information I can provide that would be useful to the SMP developers to resolve this issue?
