UEFI BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the AMI UEFI BIOS Setup
program on this motherboard. The Setup program allows users to modify the basic
system configuration and save these settings to NVRAM.
UEFI BIOS determines what a computer can do without accessing programs from a
disk. This sys tem controls most of the input and output d evices s uch as keyboard,
mouse, serial ports and disk drives. BIOS activates at the firs t stage of the booting
process, lo ading and executing the op erating s ystem. Some add itional features, s uch
as virus and pass word protection or chips et fine-tuning options are also included in
UEFI BIOS.
The rest of this manual will to guide you through the options and settings in UEFI
BIOS Setup.

Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its requirements
and prefetches data and instructio ns from the memory into the Level 2 cache that are
likely to be required in the near future. This reduces the latency associated with
memory reads.
Optio ns: Enabled (Default) / Disabled
Adjacent Cache Line Prefetch
The processor has a hardware adjacent cache line prefetch mechanism that
automatically fetches an extra 64-byte cache line whenever the processor requests for
a 64-byte cac he line. This reduces cache latenc y by making the next cache line
immediately availab le if the processor requires it as well.
