ADLINK NuPRO-E320 motherboard deployment and tuning guide

ADLINK NuPRO-E320 PICMG 1.3 System Motherboard Deployment and Optimization Practical Guide

Why still pay attention to the LGA775 platform?

In industrial automation, machine vision, data acquisition, and communication infrastructure, many systems are built on Intel Core 2 Quad/Duo and PICMG 1.3 architectures, fully utilizing PCI Express expansion capabilities and stable chipset platforms. The comprehensive replacement of these systems not only involves high hardware costs, but also faces complex issues such as driver compatibility, software licensing, and system verification. ADLINK's NuPRO-E320 is a full-size PICMG 1.3 system motherboard (SHB) that supports Core 2 Quad/Duo and Celeron processors packaged in LGA775. It is equipped with Intel Q45+ICH10 chipset, providing DDR3 memory, PCIe x16 expansion, dual Gigabit Ethernet (with optional Ethernet ports), SATA 3Gb/s, and rich I/O interfaces. It is widely used in high-end industrial computing and server fields.

As the service life of equipment increases, engineers often face challenges such as CPU cooling failure, CMOS battery depletion, serial port mode configuration, driver loss, and watchdog misoperation. This article is based on the NuPRO-E320 user manual and provides a detailed practical guide for engineers who are still maintaining these systems, covering hardware installation, jumper settings, BIOS fine tuning, driver deployment, and watchdog programming.

Installation and jumper configuration

3.1 CPU Installation (LGA775)

NuPRO-E320 adopts surface mount LGA775 socket (Socket T), installation steps:

Press down the load rod and detach it from the fixed buckle, then rotate the load rod to 135 °.

Flip the load board upwards to 100 ° and remove the protective cover with your thumb.

Aim the CPU at the foolproof notch of the socket (the golden triangle is located in the bottom left corner), and place it vertically and gently on the socket (do not push hard).

Close the load plate, press back the load rod, and secure it in the fixed buckle.

Attention: The CPU only has one correct direction, forcibly inserting it will damage the socket contacts. Be sure to operate in a power-off state.

3.2 Selection of CPU Heat Sink

The manual recommends three cooling solutions (depending on the height of the chassis):

1U level (32-20065-0000): Copper base+copper fins, fan 5500 RPM, air volume 10.48 CFM, noise 51 dBA.

3U level (32-20058-0000+34-30381-0000): Aluminum extrusion, fan 4500 RPM, air volume 57.7 CFM, noise 47.5 dBA.

Copper core reinforced type (32-20086-0000): Aluminum extrusion+copper core, fan 4500 RPM, air volume 76.9 CFM, noise 49 dBA.

Apply thermal grease evenly on the top surface of the CPU during installation, fix the heat sink, and connect the fan cable to FAN1 (4-pin, supports PWM speed regulation).

3.3 Memory Installation

Supports DDR3 800/1066 non ECC DIMMs, with a maximum of 2GB per unit (total 4GB). The dual channel mode requires DIMM1=DIMM2 to have the same capacity. Align with the foolproof notch during installation and insert vertically until the two side buckles are locked.

3.4 Key jumper settings (only 3 sets)

Jumper function settings

JBAT1 clearing CMOS 1-2 is normal, 2-3 clearing (requires power-off operation)

JP1~JP4 COM1 mode selection combination jumper determines RS-232/422/485/485+(see manual table for details)

JP11 (not labeled in the manual but mentioned in the PDF)? In the actual document, JP11 is the LCD power selection, but NuPRO-E320 does not have an LCD interface? After reviewing the PDF, it was found that there is "JP11: LCD Power Selection" after the 1.7 mechanical diagram, but there is no LCD in the specifications, which may be an early legacy, but JP11 is indeed included in the manual. The actual NuPRO-E320 does not have an LCD output, so this jumper may be invalid or used for other purposes, which we will not mention

Actually, only the JBAT1 and COM1 jumpers are important.

COM1 mode jumper (JP1~JP4) configuration:

RS-232: JP1 short 1-3, 2-4; JP2 is 1-2 short; JP3 short 1-3, 2-4; JP4 is short 1-3, 2-4 (default).

RS-422: JP1 short 1-3, 2-4; JP2 is 3-4 short; JP3 short 3-5, 4-6; JP4 is short 3-5, 4-6.

RS-485: JP1 short 3-5, 4-6; JP2 is 5-6 short; JP3 short 3-5, 4-6; JP4 is short 3-5, 4-6.

RS-485+: JP1 short 3-5, 4-6; JP2 is 5-6 short; JP3 short 3-5, 4-5; JP4 is short 3-5, 4-5.

Engineering Tip: Power off must be turned off before switching serial port mode, otherwise it may damage the serial port chip.

3.5 Quick Check of Onboard Connectors

CN1 (System Panel): 20 pin pin arrangement, providing signals such as power LED, reset, power button, hard drive LED, speaker, keyboard lock, etc.

CN2 (parallel port): 25 needles D-sub, standard SPP/ECP/EPP.

CN5 (IDE): 40 pins, supports 1 IDE device (UDMA 33/66/100).

CN3 (floppy drive): 34 needles.

CN8/CN10 (SATA): 2 7-pin SATA, and the other 2 are connected through the backplane.

CN14/CN15 (USB): 10 pin header, 2 USBs each.

CN18 (external keyboard): 5-pin, providing keyboard clock, data, and+5V.

FAN1 (CPU fan): 4-pin (GND,+12V, speed measurement, PWM control).

FAN2 (system fan): 3-pin (speed measurement,+12V, GND).

Fine tuning of BIOS

NuPRO-E320 uses AMI BIOS (press Del to enter). The following are key settings:

4.1 Boot Settings Optimization

Quick Boot: Enable skipping partial POST to speed up startup.

Quiet Boot: Disable to display detailed POST information for easy fault location.

Boot Device Priority: Adjustable order of hard drive, optical drive, USB, LAN (PXE).

4.2 CPU Configuration (Advanced → CPU Configuration)

Max CPUID Value Limit: If using an older version of Windows (such as NT 4.0), it needs to be enabled; WinXP/Vista is recommended to be disabled.

Core Multi Processing: Enable multi-core support.

4.3 IDE/SATA Configuration

SATA mode can be set to IDE, AHCI, or RAID (RAID requires an additional controller through the backplane?)? Actually, ICH10 only supports AHCI/IDE, but the manual does not mention RAID, only SATA.

This mainly sets the type of each SATA port (Auto or manually specified), usually set to Auto.

4.4 Serial Port Configuration (Super IO Configuration)

Set the base address and IRQ of COM1/COM2 (usually COM1=3F8/IRQ4, COM2=2F8/IRQ3).

Note: The mode jumper for COM1 has been determined by hardware and does not need to be selected again in BIOS.

4.5 Hardware Health Configuration

Display CPU temperature, system temperature, fan speed, and various voltages.

Fan control: Provides three modes:

Full On: The fan is at full speed.

Automatic: Intelligent temperature control, can set OFF temperature, starting temperature, starting PWM value, slope, etc., to achieve automatic speed regulation according to temperature.

PWM Manual: Manually set the PWM duty cycle (0~127).

4.6 Remote Access

Enable serial port redirection for easy debugging in environments without a monitor. The baud rate can be selected from 115200, etc.

4.7 USB Configuration

Legacy USB Support: Enable USB keyboard and mouse that can be used under DOS.

USB Functions: Select the number of USB ports to enable (default is all).

USB 2.0 Controller: Enable high-speed 480Mbps.

4.8 Chipset Settings

North Bridge: The main display device (IGD, PCI, PEG, etc.) and DVMT memory size (128MB/256MB) can be set.

South Bridge: PDA controller (audio enabled), power on/off/last state after AC power restoration.

Advanced Chipset：Onboard LAN BIOS Init（PXE）、Resume on PME#（WOL）、Power Button Mode（On/Off Or suspend.

4.9 Security and Exit

Support Supervisor/User passwords.

When exiting, changes can be saved or discarded, and optimization default values or fail safe default values can be loaded.

Driver installation guide

The accompanying driver is located in the NuPRO NuPRO-E320 directory of ADLINK All in One DVD, and is installed in the following order (using Windows XP as an example):

Chipset driver: First install the Q45 INF driver.

Display driver (VGA): GMA 4500 driver.

LAN driver (Ethernet): Intel 82574L.

TPM driver (TPM): DV version only.

Audio Daughter Board DBAudio2 : If DBAudio2 daughter card is installed.

Note: To enable AHCI, press F6 to load the SATA driver (floppy disk or USB) before installing the OS.

Practical experience of watchdog programming

The watchdog of NuPRO-E320 is based on ITE IT8718F Super I/O and can be configured through the I/O port (default 0x2E/0x2F or 0x4E/0x4F) with a timeout range of 1-15300 seconds (or minutes). The manual provides complete C language example code (see Appendix A).

6.1 Core Programming Steps

Enter configuration mode: Write a specific key (0x87, 0x01, 0x55, 0x55, or 0xAA) to the configuration port.

Select logical device 7 (WDT related registers).

Set the count value unit (seconds/minute) and timeout value (write CRF2, i.e. 0x73).

Enable reset output (via KBRST and PWROK2 pulses).

Exit configuration mode.

6.2 Example Simplified Functions (Pseudo Code)

c void SetWDT(int port, int seconds) {EnterConfig(port);//Select device 7

outportb(port, 0x07);  outportb(port+1, 0x07);

//Set the unit to seconds (bit7=1)outportb(port, 0x72);  temp = inportb(port+1);

temp |= 0x80;  temp |= 0x40; //Enable KBRST reset

outportb(port+1, temp);//Write the count value (converted to minutes if>60, but automatically judged in the example)

outportb(port, 0x73);  outportb(port+1, seconds);

ExitConfig(port);}

In actual use, the count value needs to be periodically rewritten in the main loop (feeding the dog), otherwise timeout will trigger hardware reset.

6.3 Testing Tools

The accompanying CD provides a test program that can execute ITE8718<value>[4E] under DOS, with value in seconds and the option to switch ports.

Common troubleshooting and engineering experience

Q1: No display when the system is powered on, no code on the POST card?

Check if the CPU is installed properly and if the heat sink is tightly secured (overheat protection).

Clear CMOS (JBAT1 short circuited 2-3) and then restore.

Confirm the compatibility of the memory module (it is recommended to use the same brand and specifications).

Check if the ATX 12V 4-pin power supply is connected (CN4 must be powered).

Q2: OM1 cannot work in 422/485 mode?

Confirm that the JP1~JP4 jumper settings match the required mode.

Check that the COM1 address IRQ in BIOS is not occupied by other devices.

Measure external wiring: 422 requires differential pair, 485 requires terminating resistor.

Q3: Is the SATA hard drive unrecognized or slow?

Confirm that the SATA cable is securely connected.

Set SATA mode to AHCI in BIOS (if supported by OS).

If using IDE mode, check if IDE detection is enabled.

Q4: Does the watchdog frequently reset or never reset?

Check if the feeding interval is less than the timeout value (recommended 1/3~1/2).

Confirm that StopWDT has not been misused in the program.

Check if the watchdog reset signal is interfered by other hardware (such as PWROK).

Q5: Only one dual network port is recognized?

NuPRO-E320LV only has a single Ethernet port, please confirm the model.

Check if the second Ethernet port (Onboard LAN BIOS Init) is enabled in the BIOS.

Update the network card driver to the latest version.

Maintenance and upgrade suggestions

Heat dissipation: The CPU heat sink fan will age over time. It is recommended to regularly clean the dust and monitor the speed (through the hardware health page).

CMOS battery: The onboard CR2032 has a lifespan of approximately 5-8 years. If the system time is lost, it needs to be replaced.

Capacitor aging: Although solid-state capacitors (Sanyo OS-CON, etc.) are used, electrolytic capacitors may still fail. Check for bulges.

BIOS backup: Use AMI Flash tool to backup the current BIOS in case of upgrade failure.

Spare parts reserve: Reserve CPUs, memory, and critical connection cables of the same model.
