Ciao, can someone clarify how to detect the availability  of a local APIC.
I have a single CPU Pentium II and I tried to verify that is has a local APIC by using  the asm instruction "cpuid" and looked at bit 9 of register "edx" but it was not set.
Isn't a Pentium II supposed to have an on board local APIC anyway, i.e. even on a single processor machine? Is or isn't the local APIC a CPU feature?
Thank for helping me to satisfy my curiosity.
Ciao, Paolo.
