- local APIC timer used as the source of time - PIC is still used as the hw interrupt controller as we don't have enough info without ACPI or MPS to set up IO APICs - remapping of APIC when switching paging on, uses the new mechanism to tell VM what phys areas to map in kernel's virtual space - one more step to SMP based on code by Arun C.
