3.1 Main Setup
3.1.1 AMI BIOS
This is the interface of AMI BIOS:
3.1.2 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.
3.1.3 System Memory
This part shows the auto-detected system memory. The Vortex86DX is a high performance
with 256MB 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 Vortex86DX are all
256MB onboard and the speed is 133MHz.
3.1.4 System Time:
The time format is based on the 24-hour military time clock. Press the “+” or “–“ key to
increment the setting or type the desired value into the field.
3.1.5 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.

3.2 Advanced Setup
3.2.1 IDE Configuration
OnBoard PCI IDE Controller
This can select the specification you wanted for the IDE device. This option specifies the
channel used by IDE controller on the motherboard,
Option Description
Disabled Set this value to prevent the computer system from using the onboard IDE controller.
Primary Set this value to allow the computer system to detect only the Primary IDE channel.
This includes both the Primary Master and the Primary Slave.
Secondary
Set this value to allow the computer system to detect only the Secondary IDE channel.
This includes both the Secondary Master and the Secondary Slave.
Both Set this value to allow the computer system to detect the Primary and Secondary IDE channels.
This includes the Primary Master, Primary Slave, Secondary Master, and Secondary Sla
ve. This is
the default setting.
Primary IDE Master/Slave
When you entered the IDE devices, the bios will auto-detected and show the detail information
of IDE devices. If you want to change IDE configuration, select the item and press the “Enter” to
configure the item you wanted.

3.2.3 SuperIO Configuration
You can use this screen to select options for the Super I/O settings. Use the up and down
<Arrow> keys to select an item. Use the <Plus> and <Minus> keys to change the value of the
selected option. The settings are described on the following pages. The screen is shown below.
Onboard Floppy Controller
This item specifies the Floppy used by the onboard Floppy controller. The settings are
Disabled or Enabled.
Floppy Drive Swap
This option allows you to Enabled or Disabled the Floppy Drive Swap.
3.2.4 USB Configuration
USB Functions
Set this value to allow the system to enable or disable the onboard USB ports. The Optimal
and Fail-Safe default setting is Enabled.
Option Description
Disabled This setting makes the onboard USB ports unavailable.
Enabled This setting allows the use of the USB PORTS. This is the default setting.
Legacy USB Support
Legacy USB Support refers to the USB mouse and USB keyboard support. Normally if this
option is not enabled, any attached USB mouse or USB keyboard will not become available until a
USB compatible operating system is fully booted with all USB drivers loaded. When this option is
enabled, any attached USB mouse or USB keyboard can control the system even when there is no
USB drivers loaded on the system. Set this value to enable or disable the Legacy USB Support.
The Optimal and Fail-Safe default setting is Disabled.
Option Description
Disabled Set this value to prevent the use of any USB device in DOS or during system boot.
This
is the default setting.
Enabled Set this value to allow the use of USB devices during boot and while using DOS.
Auto This option auto detects USB Keyboards or Mice and if found, allows them to be
utilized
during boot and while using DOS.
