You need to know the apic id before you can start code on the second cpu. I recall seeing how how this is set in the BIOS programmers guide.

There is no good reason to run to multiple cpus in auto.c Eric _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
