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.
Please 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
If you need to add other parameters, pls add <space>/? after the order format
Example：Afudos 7893T100.rom /P /B /C /N /X
Reminder:
1. BIOS upgrading is only executed when your system goes wrong.
2. Please use the BIOS read-write programs 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 completing the upgrading, please press <Delete> or <Del> to enter BIOS SETUP to
optimize BIOS, then press F10 to save and exit.
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 Settings
The computer starts up and system conducts self-detection, then following message pops up
on the screen :” Del->SETUP” . Press Del key and system enters BIOS SETUP interface after
POS-7893 High Performance POS Motherboard

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

watchdog reference code（ASM）
--------------------------------------------------------------------------------------------------------------
Set the port to realize watchdog function through DEBUG order, so that it can carry out
Watchdog Timer’s various functions.
Port Instruction:
2EH: Address Register
2FH: Data Register
Example: Set Watchdog Timer for 30 seconds, run DEBUG command in DOS mode:
C:\>debug
-o 2e 87
-o 2e 01
-o 2e 55
-o 2e 55 : Decode
-o 2e 07 : Select Register
-o 2f 07
-o 2e 72
-o 2f c0 : set the timing unit as second (set minute: o 2f 40)
-o 2e 73
-o 2f 1e : Select time =30seconds
-q : Exit

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
BIOS
Basic input/output system. It is a kind of software including all in/out control code interface
in PC. It will do hardware testing while system is booting, and then the O/S runs. BIOS provides
a interface between O/S and hardware and is stored in a ROM chip.
BUS
In a computer system, it is the channel among different parts for exchanging data; it is also
a set of hardware lines. BUS here refers to part lines inside CPU and the main components of
system memory.
Chipset
Chipset is a Integrated set of chips for executing one or more related functions。Here it
refers to a system level chipset structured by Southbridge & Northbridge; It decides the
structure and main functions of motherboard.
CMOS
Complementary Metal-Oxide Semiconductor, which is a widely used semiconductor with
the characteristics of high-speed and low-power. COMS here refers to part of space on-board
CMOS RAM for saving date, time, system information and system parameter,ect.
COM
Computer-Output Microfilmer.A universal serial communication interface, usually adopts
normative OB 9 connector.
DIMM
POS-7893 High Performance POS Motherboard
53
Dual-Inline-Memory-Modules. It is a small circuit board with memory chipset providing 64
bit memory bus width.
DRAM
Dynamic Random Access Memorizer. It’s a normal type of memory often with a transistor
and a capacitance to store 1 bit. With the development of the technology, more and more types
of DRAM with different specifications exist in computer applications. For example:
SDRAM/DDR SDRAM/RDRAM.
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, or cellphone.
LAN
Network interface. Network grouped by correlative computers in a small area, generally in
a company or a building. Local area network is buildup by sever, workstation, some
communications links. Terminals can access data and devices anywhere through cables, which
enables users to share costly devices and resource.
LED
Light-Emitting Diode. A semiconductor device that shines when power supply is connected,
It is often used to denote information directly, for example, to denote power on or HDD working
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 the system is booting, BIOS will do an uninterrupted
testing to the system, including RAM, keyboard, hard disk driver etc.to check if all the
POS-7893 High Performance POS Motherboard
54
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 only 6PIN; it also can connect other devices, like modem
USB
It is the Universal Serial Bus for short. A hardware interface adapts to low speed
peripherals, 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 work on.
