Vortex86 Family Overview

DM&P x86 Semiconductor is proud to provide the Vortex86SX RISC Microprocessor, DDR2
128MB onboard, which is based on MPU structure. It is the x86 SoC (System on Chip) with

0.13 micron process and ultra low power consumption design (less than 1 watt). This
comprehensive SoC has been integrated many features, such as various I/O (RS-232, Parallel,
USB and GPIO), BIOS, WatchDog Timer, Power Management, MTBF counter, LoC (LAN on
Chip), JTAG etc., into a BGA packing single chip.

The Vortex86SX is a high performance, which is compatible with DOS and Linux. It integrates
32KB write through direct map L1 cache, PCI Rev. 2.1 32-bit bus interface at 33 MHz, SDRAM,
DDR2, ROM controller, IPC (Internal Peripheral Controllers with DMA and interrupt
timer/counter included), Fast Ethernet MAC, FIFO UART, USB2.0 Host and IDE controller into
a System-on-Chip (SoC) design.

Furthermore, this outstanding Vortex86SX SoC can not only meet the requirements of
embedded applications, such as Electronics Billboard, Firewall Router, Industrial
Single-Board-Computers, Receipt Printer Controller, Thin Client PC, Auto Vehicle Locator,
Finger Print Identification, Web Camera Thin Server, RS232-to-TCP Transmitter, but also can
meet the critical temperature demand, spanning from -40 to +85 degree C.

The Vortex86SX is a high performance and fully static 32-bit X86 processor with the
compatibility of Windows based, Linux and most popular 32-bit RTOS. It also integrates 32KB
write through direct map L1 cache, PCI rev. 2.1 32-bit bus interface at 33 MHz, SDRAM, DDR2,
ROM controller, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter
included), Fast Ethernet MAC, FIFO UART, USB2.0 Host and IDE controller within a single
456-pin BGA package to form a system-on-a-chip (SOC). It provides an ideal solution for the
embedded system and communications products (such as thin client, NAT router, home
gateway, access point and tablet PC) to bring about desired performance.

AMI BIOS Setup

Introduction

This manual describes AMI's Setup program, which is built into the ROM BIOS. The Setup
program allows users to modify the basic system configuration. This speci al information is then
stored in battery-backed RAM so that it retains the Setup information when the power is turned
off.

Starting Setup

When the system is powered on, use the bios set program when you start up your system,
reconfiguring your system, or press “Delete” promptly to run setup. This section will explain
how to configure your system using this utility. And this change will be recognized and record
them in the CMOS RAM of the SPI chip.

When you start up the computer, the system provides you the opportunity to set the program.
Press the “del” during the P.O.S.T ( Power-on Self-Test) to enter the prog ram setting. And the
POST will continue with the test routines. And the firmware chip will store the setup utility on
the board. However, if you want to enter the setup af ter the POST, you can press Ctrl + Alt +
Del simultaneously or turn off the powe r then back on.

The following pages are meant to give you a better insight into the options you have to setup
your system. Many options depend on the choice of type of memory, memory speed,
peripherals and the programs that you will be running. The effective of these settings are
related to system performance that can destabilize operation. W e urge you to proceed with
caution

.

1.1.1 AMIBIOS

This is the information of AMIBIOS.

1.1.2 Processor

This part shows the auto-detected CPU specification.
DM&P Semiconductor is the Vortex86SX 32-Bit Microprocessor, DDR2 128MB onboard,
which is based on x86 structure. It is the x86 SoC (System on Chip) with 0.13 micron process
and ultra low power consumption design (less than 1 watt)The CPU on the Vortex86SX is a
high performance and fully static 32-bit X86 processor with the compatibility of Windows based,
Linux and most popular 32-bit RTOS.

1.1.3 System Memory

This part shows the auto-detected system memory.

The Vortex86SX is a high performance with 128MB RAM and speed 133MHz onboard and
fully static 32-bit x86 processor, which is compatible with DOS and Linux. It integrates 32KB
write through direct map L1 cache, PCI Rev. 2.1 32-bit bus interface at 33 MHz, SDRAM,
DDR2, ROM controller, IPC (Internal Peripheral Controllers with DMA and interrupt
timer/counter included), Fast Ethernet MAC, FIFO UART, USB2.0 Host and IDE controller into
a System-on-Chip (SoC) design.

The Vortex86SX are all 128MB onboard and the speed is 133MHz.

1.1.4 System Time:

The time format is based on the 24-hour military time clock

DMP Electronics INC.

Press the + or - key to increment the setting or type the desired value into the field.

1.1.5 System Date:

Press the + or - to set the date you wanted .
The BIOS determines the day of the week from the other date information; this field is for
information only.

1.1.6 MTBF

Mean time between failures (MTBF) is the mean (average) time between failures of a system,
the reciprocal of the failure rate in the special case when the failure rate is constant.
Calculations of MTBF assume that a system is 'renewed', i.e. fixed, after each failure, and then
returned to service immediately after failure. A related term, mean distance between failures,
with a similar and more intuitive sense, is widely used in transport industries such as railways
and trucking. The average time between failing and being returned to service is termed mean
down time (MDT).g

1.1.7 System Fault

As the system detect the illegal command or serious error when boot, it will show on this
screen.

Setup for AMIBIOS

Type [Auto]

DMP Electronics INC.

Select the type of IDE drive. Setting to Auto allows automatic selection of the appropriate IDE
device type. Select CDROM if you are specifically configuring a CD-ROM drive. Select ARMD
(ATAPI Removable Media Device) if your device is either a ZIP, LS-120, or MO drive.

ATA (PI) 80 pin Cable De tection

Set this option to select the method used to detect the ATA (PI) 80 pin cable. The
Optimal and Fail-Safe setting is Host & Device.

The use of an 80-conductor ATA cable is mandatory for running Ultra ATA/66, Ultra
ATA/100 and Ultra ATA/133 IDE hard disk drives. The standard 40-conductor ATA cable
cannot handle the higher speeds.
80-conductor ATA cable is plug compatible with the standard 40-conductor ATA cable.
Because of this, the system must determine the presence of the correct cable. This detection
is achieved by having a break in one of the lines on the 80-conductor ATA cable that is
normally an unbroken connection in the standard 40-conductor ATA cable. It is this break that
is used to make this determination. The AMIBIOS can instruct the drive
to run at the correct speed for the cable type detected.

Setup for AMIBIOS

DMP Electronics INC.

Hard Disk Delay

Delay for a connected HDD (Secs). The length of time in seconds the
BIOS will wait for a hard disk to be ready for operation. If the hard drive
is not ready, the BIOS might not detect the hard drive correctly. The range is from 0~8
seconds.
**We suggest the delay time select 2 sec.delay.
