Chapter 3 BIOS Setup
AMI BIOS Flash
BIOS functions as a bridge connecting hardware and operating system. Hardware and
software are upgrading all the time, so when your system goes wrong, for example, your
system can not support the newest CPU, you need to upgrade BIOS to keep up with the latest
technology.
AFUDOS.EXE is the FLASH IC program for BIOS to upgrade, which needs to be run in DOS
mode.
Pls use a boot disk to load DOS, then run AFUDOS.EXE to upgrade BIOS（ for example: write
XXXX.ROM into FLASH IC ）
Order Format:
A:\ Afudos XXXX.rom / P /B /C /N /X
If you need to add other parameters, pls add <space>/? after the order format
Remark:
1. BIOS upgrading is only executed when your system goes wrong.
2. Please use the upgrading program in the CD-ROM provided by us or download the latest
version of the upgrading program on-line
3. Please do not power off or reboot the system when upgrading, otherwise, the BIOS maybe
be damaged or system may not be able to boot again.
4．After upgrading the BIOS, manually load defaults
5．Please backup your BIOS before upgrading
AMI BIOS Description
When the computer is power on, BIOS will conduct self-diagnosis to its hardware on
motherboard and configure hardware parameter, finally the operating system will take control.
BIOS is the communication bridge between hardware and O/S. Correct configuration of BIOS
is critical for maintaining system stability and its optimized performance.
BIOS Setup:
After finishing the self-diagnosis, following message will show on the screen:
DEL->SETUP, pls press DEL，then system will enter BIOS setup interface automatically atfer
doing the IDE detection:

1. Power on or reboot the computer, self-detection information will show:
2. When message shows as "Press <DEL> to enter setup"，pls press <DEL>, then enter into
BIOS SETUP Program.
3. Use the “←↑→↓”to choose the option which your want to modify, press <Enter> and then
the sub-menu.will show.
4. Use the “←↑→↓”and <Enter> to modify the value; press”Enter” to modify BIOS options
that you choose
5. At any time, press<Esc> can go back to the father-menu.

Appendix 2: Glossary
ACPI
Advanced Configuration and Power Management. ACPI specifications allow O/S to control most
power of the computer and its add-ons
Windows 98/98SE，Windows 2000 and Windows ME all support this function, which enable users to
manage the system power flexibly.
BIOS
Basic input/output system. It’s a kind of software including all in/out control code interface in PC. It will
do hardware testing while system is booting, then system runs, it provides an interface between OS
and hardware. BIOS is stored in a ROM chip.
BUS
In a computer system, it is the channel among different parts for exchanging data; it’s also a group of
hardware lines. BUS here refers to part lines inside CPU and main components of memory.
Chipset
Integrated chips for executing one or more functions. Here “Chipset” refers to system level chipset
structured by Southbridge & Northbridge; it determines motherboard’s structure and main functions.
CMOS
Complementary Metal-Oxide Semiconductor, a widely used semiconductor with the characteristic of
high speed but low-power-consumption. CMOS here refers to part of reserved space in on-board
CMOS RAM, for saving date, time, system information and system parameter etc.
COM
Computer-Output Microfilmer. A universal serial communication interface, usually adopts normative
DB9 connector.
DIMM
Dual-Inline-Memory-Module. It’s a small circuit board with memory chipset, providing 64bit RAM bus
width.
MITX-6930 Intel Cedar Trail Based Mini-ITX Motherboard with 3G Connectivity
DRAM
Dynamic Random Access Memorizer. It’s a normal type of universal memory often with a transistor
and a capacitance to store 1 bit. With the development of the technology, more and more types of
ORAM with various specifications exist in computer application, such as SDRAM, DDR SDRAM and
RDRAM
I2C
I2C（Inter－Integrated Circuit）, generically referred to as two-wire interface, is a multi-master serial
single-ended computer bus invented by Philips that is used to attach low-speed peripherals to a
motherboard, embedded system, cellphone, or other electronic device.
LAN
Network interface. Network grouped by correlative computers in a small area, generally in a company
or a building. Local area network is generally buildup by sever, workstation, some communication
links. Terminals can access data and devices anywhere through cables so that many users can share
costly device and resource.
LED
Light-Emitting Diode. a semiconductor device that shines when power supply is connected, often
used to denote info directly by light, for example, to denote power on or HDD work normally.
PnP
Plug-and-Play. It is a specification that allows PC to configure its external devices automatically and
can work independently without the manual operation by its user . To achieve this function, its BIOS
should be able to support PnP and a PnP expansion card.
POST
Self-test when power on. While booting, BIOS will do an uninterrupted testing to the system, including
RAM, keyboard, hard disk driver etc. to check if all the components are in normal situation and work
well.
PS/2
A keyboard & mouse connective interface specification developed by IBM.PS/2 is a DIN interface with
MITX-6930 Intel Cedar Trail Based Mini-ITX Motherboard with 3G Connectivity
only 6PIN; it also can connect other devices, like modem.
USB
It’s Universal Serial Bus for short. A hardware interface adapts to low speed external devices, and is
always used to connect keyboard, mouse etc. One PC can connect maximum 127 USB devices,
providing 12Mbit/s transmit bandwidth；USB supports hot swap and multi- data stream, namely, you
can plug USB devices while system is running, system can auto-detect and makes it w
