Detailed Description

I/O APIC Identification.

The IOAPICID register is register number 0x0. The I/O APIC's ID will be read from the system configuration tables (provided by the BIOS) during boot. The number can be queried by calling APIC::getIOAPICID(). During initialization, this number must be written to the IOAPICID register.
