I have both APIC and HTT flags in my P4, but when I try to load kernel
compiled with APIC_IO and SMP, I got panic:

pmap_bootstrap: no local apic! (non-SMP hardware?)

Is it motherboard or BIOS? I have no Hyperthreading setting in the BIOS,
but PIC or APIC modes (both not works with MP kernel). Motherboard is ASUS 
P4B533.
