Q: There is a new option "APIC" in "Advanced BIOS Features" after upgraded to BIOS 38. What is the effect of "APIC" option? [TH7II/TH7II-RAID]
A: APIC assigns interrupt signals to a specific processor on Multi-Processor system. It provides additional IRQs beyond conventional 16 IRQs under Windows 2000 or XP.
You MUST enable APIC option and then reinstall OS if you want to achieve the benefit of APIC function under Windows 2000 or XP. (Note: Do no change the APIC option, no matter enable or disable it, after successfully installed the Windows system, otherwise it may cause system abnormal or crashed.)
