APIC Mode
The APIC Mode BIOS feature is used to enable or disable the motherboard’s APIC (Advanced Program-
mable Interrupt Controller). If your single-processor motherboard supports APIC and you are using a Win32
operating system (Windows NT, 2000 and XP), it’s recommended that you enable this feature to allow faster
and better IRQ handling. If you are using a multiprocessor motherboard, you must enable this feature
because it’s required for IRQ handling in multiprocessor systems.
OS Select for DRAM>64MB
Set to OS2 if the system memory size is greater than 64 MB and the operating system is OS/2.
Limit CPUID MaxVal
This item belongs to the Prescott CPU family. Enable it when the Prescott CPU family is installed on
