Interrupt Mode

Common Options : PIC, APIC

Quick Review

This BIOS feature is used to enable or disable the motherboard's APIC (Advanced Programmable Interrupt Controller). The APIC provides multiprocessor support, more IRQs and faster interrupt handling.

However, it is only supported by newer operating systems like Microsoft Windows NT, Windows 2000 and Windows XP. Older operating systems like DOS or Windows 95/98 do not support this feature.

It is recommended that you select APIC if you are using a newer operating system like Windows XP. Select PIC only if you are using an older operating system like DOS or Windows 95/98.
