To power on Nuvo-2000 using the power button on the front panel

This is the simplest way to turn on your Nuvo-2000. The power button on the front panel is


Nuvo-2000 User’s Manual a non-latched switch and behaves an ATX-mode on/off control. As DC power is connected, push the power button and then system is on as well as the blue LED of power button is on.

Push the button when system is on can turn off the system. If your operating system supports ATX power mode (i.e. Microsoft Windows or Linux), push the power button causes a pre-defined system behavior, such as shutdown or hibernation.

To power on Nuvo-2000 using an external latched switch (AT-mode)

For an application which places Nuvo-2000 inside a cabinet, it’s useful to control the on/off of the system using an external switch. Nuvo-2000 provides an on-board 3-pin wafer connector (for detail, please refer to section 2.3) for connecting a latched/non-latched switch and behaves either AT-mode or ATX-mode power on/off control.

When using the AT-mode on/off control, you need a latched switch. The external latched switch controls the feed-in of DC power. When the switch is closed, the DC power is break-off. When it’s opened, the DC power is feed-in. To power on Nuvo-2000 using an external latched switch (AT-mode), please follow the steps listed below.

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. the BIOS setting menu. the BIOS option as [ON]. This setting allows the system to turn on after external DC power is feed-in. Please refer to section

4.1 for the instruction of configuring this option.

4. Prepare a latched switch with a 2-pin, 2.0mm pitch connector.

5. Connect the latched switch to the AT pin and GND pin of the on-board wafer connector.



6. When the latched switch is closed, the DC power is break off and system is turn off.

When the latched switch is opened, the DC power is feed-in, and, with the correct setting of “Power On after Power Failure” BIOS option, the system is turn on.

To power on Nuvo-2000 using an external non-latched switch

(ATX-mode)

For an application which places Nuvo-2000 inside a cabinet, it’s useful to control the on/off of the system using an external switch. Nuvo-2000 provides an on-board 3-pin wafer connector (for detail, please refer to section 2.3) for connecting a latched/non-latched switch and behaves either AT-mode or ATX-mode power on/off control.

When using the ATX-mode on/off control, you need a non-latch switch. The external non-latched switch acts exactly the same as the power button on the front panel. To power on Nuvo-2000 using an external non-latched switch (ATX-mode), please follow the steps listed below.

1. Prepare a non-latched switch with a 2-pin, 2.0mm pitch connector.

2. Connect the non-latched switch to the ATX pin and GND pin of the on-board wafer connector.



3. Push the non-latched switch and then system is on (the blue LED of power button on the front panel is on at the same time). Push the non-latched switch when system is on can turn off the system. If your operating system supports ATX power mode (i.e.

Microsoft Windows or Linux), push the power button causes a pre-defined system behavior, such as shutdown or hibernation.

To power on Nuvo-2000 using Wake-on-LAN function

Wake-on-LAN (WOL) is a mechanism to wake up a computer system from a S3 (standby),

S4 (Hibernate) or S5 (system off with standby power) state via issuing Subnet Directed

Chapter 4 BIOS and Driver

4.1 BIOS Settings

Nuvo-2000 is shipped with factory-default BIOS settings cautiously programmed for best performance and compatibility. In this section, we’ll illustrate some of BIOS settings you may need to modify. Please always make sure you understand the effect of change before you proceed with any modification.

COM1 Operating Mode

COM1 of Nuvo-2000 supports RS-232 (full-duplex), RS-422 (full-duplex) and RS-485

(half-duplex) mode. You can set the COM1 operating mode via BIOS settings. Another option in BIOS called “Slew Rate” defines how sharp the rasing/falling edge is for the output signal of COM1. For long-distance RS-422/485 transmission, you may set the “Slew Rate” option as “High” to improve signal quality.

.

To set COM1 operating mode:

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. to Æ [Peripheral Configuration] . the to a proper mode for COM1 of your Nuvo-2000.



SATA Controller Mode

The SATA controller of Nuvo-2000 supports IDE (non-AHCI) and AHCI mode. IDE mode is a legacy interface and is compatible with most storage devices. AHCI mode, which exposes

SATA's advanced capabilities such as hot swapping and native command queuing, are supported in several later version of operating systems.

Our suggestion of how to set SATA controller mode is

- If you’re using Windows XP, Linux kernel earlier than 2.6.19, or you want to use a CF card, you should select IDE+SATA (Non-AHCI) mode.

- If you’re using Windows Vista, Windows 7, or Linux kernel from 2.6.19 onward, you can select AHCI mode for better performance.

To set SATA controller mode:

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. to Æ [SATA Configuration] . the to a proper mode for your Nuvo-2000.



Boot Display Device

Nuvo-2000 has an Integrated Intel® GMA 3150 graphics engine in its Atom D525 processor.

For some applications, you may need to install and use a stand-alone graphics card for display output. When using a PCI or PCI Express graphics card, you should set a proper boot display device in BIOS in advance.

To set the boot display device:

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. to Æ [Video Configuration] . the to a proper device for your Nuvo-2000. z Select “Int. Graphics Device” if using integrated Intel® GMA 3150 graphics engine z Select “PCI Graphics Card” if using a PCI graphics card z Select “PCI-E Graphics Card” if using a PCI Express graphics card



PCI Latency Timer

PCI latency timer determines how long a PCI device can occupy the PCI bus for data transfer. Setting a higher value of PCI latency timer will increase the data throughput of a single PCI device, but also increase the waiting time for other PCI devices. Our suggestion for specifying the value of PCI latency timer is: z If the PCI devices installed are operating with low data throughput, you should specify a smaller value of PCI latency timer to decrease the waiting time for PCI devices. z If there is a PCI device usually requests a “burst” data transfer (e.x. a Gigabit Ethernet card), a larger value of PCI latency timer is suggested.

To set the PCI latency timer:

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. to Æ [Chipset Configuration] . the to a proper value for your Nuvo-2000.



Trip Point for CPU Thermal Throttling

To avoid CPU from overheating in some circumstances, Intel® provides a measure called

“thermal throttling” to protect CPU. When CPU core temperature reaches the throttling-on temperature, CPU start to insert idle clock cycles to reduce heat generated. Since Intel®

Atom D525 processor has a Tj max

(core temperature limit) of 100°C, we suggest you set a value of 85°C as the throttling-on temperature.

To set CPU thermal throttling temperature:

1. When Nuvo-2000 boots up, press F2 to enter BIOS setup utility. to Æ [Advanced CPU Control] Æ [Thermal Trip Points Setting] . the to a proper value for your Nuvo-2000.
