1-3. SAFETY PRECAUTIONS
Follow the messages below to avoid your systems from damage:
1. Keep your system away from static electricity on all occasions.
2. Prevent electric shock. Don’t touch any components of this card when the card
is power-on. Always disconnect power when the system is not in use.
3. Disconnect power when you change any hardware devices. For instance, when
you connect a jumper or install any cards, a surge of power may damage the
electronic components or the whole system.

2-3. HOW TO SET THE JUMPERS
You can configure your board by setting jumpers. Jumper is consists of
two or three metal pins with a plastic base mounted on the card, and by
using a small plastic "cap", Also known as the jumper cap (with a metal
contact inside), you are able to connect the pins. So you can set-up your
hardware configuration by "open" or "close" pins.
The jumper can be combined into sets that called jumper blocks. When
the jumpers are all in the block, you have to put them together to set up
the hardware configuration. The figure below shows how this looks like.
JUMPERS AND CAPS
If a jumper has three pins (for examples, labelled PIN1, PIN2, and PIN3),
You can connect PIN1 & PIN2 to create one setting by shorting. You can
either connect PIN2 & PIN3 to create another setting. The same jumper
diagrams are applied all through this manual. The figure below shows
what the manual diagrams look and what they represent.

PMB-881LF USER′S MANUAL
4-1. INTRODUCTION
The board PMB-881LF uses an AMI Aptio BIOS that is stored in the Serial
Peripheral Interface Flash Memory (SPI Flash) and can be updated. The SPI
Flash contains the BIOS Setup program, Power-on Self-Test (POST), the PCI
auto-configuration utility, LAN EEPROM information, and Plug and Play
support.
Aptio is AMI’s BIOS firmware based on the UEFI (Unified Extensible Firmware
Interface) Specifications and the Intel Platform Innovation Framework for EFI.
The UEFI specification defines an interface between an operating system and
platform firmware. The interface consists of data tables that contain platformrelated information, boot service calls, and runtime service calls that are available
to the operating system and its loader. These provide standard environment for
booting an operating system and running pre-boot applications.
Following illustration shows Extensible Firmware Interface’s position in the
software stack.

Chapter 4 AMI BIOS Setup
PMB-881LF USER′S MANUAL
Page: 4-3
EFI BIOS provides an user interface allow users the ability to modify hardware
configuration, e.g. change system date and time, enable or disable a system
component, decide bootable device priorities, setup personal password, etc.,
which is convenient for modifications and customization of the computer system
and allows technicians another method for finding solutions if hardware has any
problems.
The BIOS Setup program can be used to view and change the BIOS settings for
the computer. The BIOS Setup program is accessed by pressing the <Del> or
<F2> key after the POST memory test begins and before the operating system
boot begins. The settings are shown below.
