ADLINK NuPRO-E340 PICMG 1.3 Industrial Motherboard Deployment and BIOS Optimization Complete Guide

In the fields of industrial visual inspection, high-speed data acquisition, and high-end motion control, the PICMG 1.3 standard system motherboard (SHB) is gradually replacing the traditional PICMG 1.0 platform with its PCIe x16 high bandwidth expansion capability and native support for the latest peripheral interfaces. ADLINK's NuPRO-E340 full-size single board computer, equipped with second-generation Intel ®  Core ™  I7/i5/i3 processors (LGA1155) and Intel ®  The Q67 Express chipset not only provides powerful computing performance, but also introduces USB 3.0, SATA 6 Gb/s, Intel, and more ®  AMT 7.0 remote management and TPM 1.2 hardware security module make it an ideal choice for demanding industrial automation and intelligent vision systems. This article will comprehensively analyze the hardware characteristics, key component installation, BIOS deep tuning, system resource allocation, and practical application of watchdog and remote management functions of the board from the perspective of actual engineering deployment, providing engineers with a full process technical reference from power on to stable operation.

Differences in Product Positioning and Core Architecture

The NuPRO-E340 follows the PICMG 1.3 standard and provides PCIe x16, PCIe x4, and traditional 32-bit/33MHz PCI buses through the Gold Finger, compatible with industrial backboards that support PCIe expansion (such as ADLINK EBP-13E2). Compared with the NuPRO-A40H of the same series PICMG 1.0, the core advantages of E340 are:

Chipset upgrade: using Intel ®  Q67 PCH， Support Intel ®  Active Management Technology 7.0（AMT）， Implement out of band remote management;

Storage and transmission acceleration: onboard 2 SATA 6 Gb/s interfaces (blue) and 2 USB 3.0 rear ports to meet high-speed data throughput requirements;

Scalability: PCIe x16 slots (for high-performance graphics or capture cards), PCIe x4, and an additional 4 USB 2.0 and 2 SATA 3 Gb/s can be accessed through the backplane;

Security Enhancement: The optional Infineon SLB 9635 TT 1.2 TPM chip supports hardware level key storage and platform integrity verification.

The processor supports the second-generation Core ™  Series (32nm, such as i7-2600, i5-2400, i3-2120, Pentium) ®  G850）， Integrated dual channel DDR3 1066/1333 MHz memory controller (up to 8GB) and Intel ®  HD Graphics。 The chipset is connected to the CPU through DMI (Direct Media Interface) and FDI (Flexible Display Interface), providing display output (rear VGA+onboard DVI-D pin).

Key points of mechanical dimensions and I/O layout

The size of the board meets the standard PICMG 1.3 full-length specification (see the mechanical diagram in the manual for details), and attention should be paid to aligning the fixing holes with the backplate during installation. The rear panel interface includes:

Dual RJ-45 (LAN1 supports AMT, LAN2 is standard gigabit);

VGA port (DB-15);

2 USB 3.0 (blue, can only be used after the operating system loads the driver, does not support DOS/BIOS booting);

PS/2 keyboard/mouse (onboard pin, requires bracket).

Distribution of main connectors inside the board (see layout diagram):

Memory slots: DIMM1/DIMM2, supporting dual channels;

SATA: CN2/CN4 (blue, 6Gb/s), CN5/CN7 (black, 3Gb/s);

USB 2.0: CN3/CN6/CN8/X1 four sets of pins, a total of 8 ports;

Serial ports: CN10 (COM1, RS-232/422/485/485+), CN11~CN16 (COM2~COM6, pure RS-232);

DVI-D: CN17 pin, matched with optional bracket;

Parallel port: CN15, standard 25 pin;

HD Audio：CN9， Used for DB-Audio2 daughter cards;

System panel: CN23, integrated power/reset/HDD LED/speaker/keyboard lock and other control signals;

Power supply: CN24 (4-pin ATX 12V), must be connected to+12V to start;

Fans: FAN1 (CPU, supports PWM speed regulation), FAN2 (system, fixed full speed).

Practical installation of core components

1. CPU installation (LGA1155)

The operation process is exactly the same as NuPRO-A40H: disconnect the power, wear an anti-static wristband, unlock the lever, remove the protective cover, align the CPU golden triangle with the Pin1 symbol of the socket, place it vertically (foolproof design), close the cover and lock it. It is strictly prohibited to touch the socket spring to avoid deformation and poor contact.

2. Heat sink and fan

The CPU must be equipped with an active heat sink, the FAN1 interface is 4-pin PWM, and supports BIOS intelligent speed regulation (see the hardware monitoring section later). The application of thermal conductive silicone grease should be evenly thin, and the fixing screws should be gradually tightened diagonally to prevent crushing the core.

3. Memory installation

Supports 1GB, 2GB, and 4GB non ECC buffered DDR3 1333/1066 modules, with a maximum total capacity of 8GB (4GB per module). To achieve optimal dual channel performance, it is recommended that the capacity, rate, and CAS delay of both channels be consistent. During installation, first bend the buckle outward and insert it vertically into the anti mistake notch until the buckle automatically returns to its original position.

4. Power connection

The 4-pin+12V interface of CN24 must be connected, otherwise the motherboard cannot start. If the power supply only has a large 4-pin, ADLINK adapter cable (P/N 30-00006-0000) can be used. At the same time, the ATX power control signals (PSON #, 5VSB) and power button (PWRBT #) in CN23 need to be correctly connected to the backplane to achieve ATX soft power on/off.

Jumper configuration and special functions

Default Status Description of Jumper Number Function

JBAT1 Clear CMOS 1-2 (Normal) After power failure, short circuit 2-3 for about 5 seconds to clear NVRAM

The selection of JP1-4 COM1 mode is shown in the manual table, and is set to RS-232, RS-422, RS-485, or RS-485+(full duplex) through four sets of jumper combinations. For specific combinations, please refer to Section 2.4

COM1 mode switching detailed combination (excerpted from the manual):

RS-232: JP1 1-2, JP2 1-3&2-4, JP3 1-3&2-4, JP4 not connected (or according to the table);

RS‑422：JP1 3‑4，JP2 3‑5&4‑6，JP3 3‑5&4‑6，JP4 1‑3&2‑4；

RS‑485：JP1 5‑6，JP2 3‑5&4‑6，JP3 3‑5&4‑6，JP4 1‑3&2‑4；

RS-485+: JP1 5-6, JP2 3-5&4-6, JP3 3-5&4-6, JP4 3-5&4-6 (note that the difference from standard RS-485 lies in JP4).

Be sure to ensure that the jumper settings are consistent with the external device level standards, otherwise it may cause communication abnormalities or damage to the port.

Essentials of System Resources and Interrupt Routing

For complex systems that require multiple expansion cards, it is crucial to allocate IRQ reasonably and avoid conflicts.

System memory mapping: 640KB~768KB is for video buffer, 768KB~896KB is for PCI expansion ROM (including VGA BIOS and LAN PXE ROM), and 1MB or more is for system BIOS and APIC space.

DMA channels: channels 0/1/3 are reserved for parallel ports (LPT), channel 2 is a floppy drive, channel 4 is cascaded, and channels 5-7 are open.

I/O addresses: Typical allocations include COM1=3F8h (IRQ4), COM2=2F8h (IRQ3), LPT=378h (IRQ7). The SIO (ITE8783) configuration index is located at 2Eh/2Fh or 4Eh/4Fh.

IRQ routing (APIC mode): PCIe root ports and onboard devices (such as 82574L network cards, SATA controllers, USB EHCI) are assigned IRQs 16~23. If inserting a third-party PCI card, be careful to avoid sharing the same PIRQ line with onboard devices. BIOS can manually adjust the mapping from PIRQ to INT A~D (refer to PCI interrupt routing table). For ISA cards, corresponding IRQs need to be reserved in the BIOS to prevent them from being preempted by PCI devices.

Watchdog Timer (WDT) Programming Guide

The watchdog of NuPRO-E340 is controlled by the ITE8783 Super I/O chip and can be programmed through the I/O port. The official provides C language sample code based on DOS/Windows (see Appendix A.1). The core operations include:

Enter configuration mode: Write a specific key sequence (0x87, 0x01, 0x55, 0x55, or 0xAA) to 2Eh (or 4Eh);

Select logical device 7 (WDT device);

Set the counting unit and value: select seconds or minutes in register 0x71, and write timeout values (1-255) in register 0x73;

Enable WDT output: trigger system reset through KBRST signal;

Exit configuration mode: Write 0x02 to 2Eh and 0x02 to 2Fh.

Example code snippet:

outportb(0x2E, 0x87);  outportb(0x2E, 0x01);  outportb(0x2E, 0x55);  outportb(0x2E, 0x55); //Enter

outportb(0x2E, 0x07);  outportb(0x2F, 0x07); //Select device 7

outportb(0x2E, 0x71);  outportb(0x2F, 0x60); //Set seconds to enable keyboard/mouse interrupt

outportb(0x2E, 0x73);  outportb(0x2F, count); //Write timeout value

outportb(0x2E, 0x02);  outportb(0x2F, 0x02); //Exit

Under the operating system, it is necessary to write driver programs or use SEMA interfaces (if provided) to simplify operations. For Windows, ADLINK provides driver support, and the application layer can be refreshed through APIs.

Driver installation and special precautions

The accompanying DVD provides Windows XP/7 (32/64 bit) and Linux drivers. Suggested installation sequence:

Chipset driver (Intel INF Update);

Display driver (requires installation of. NET Framework 3.5 SP1 first);

Network driver (Intel 82579LM/82574L);

Intel Rapid Storage Technology (if using RAID/AHCI, drivers need to be preloaded through F6 during OS installation);

USB 3.0 driver (required only for Windows, included with Linux kernel 2.6.31+);

AMT drive (ME_SW);

TPM driver (if equipped);

Audio driver (only when using DB-Audio2 daughter card).

Key Reminder:

The USB 3.0 port cannot be used for installing the operating system as the installation program does not have built-in drivers. Please use a USB 2.0 port or optical drive.

If RAID or AHCI is enabled, be sure to prepare an F6 floppy disk image before installing Windows, otherwise the system will not recognize the hard disk.

Linux distributions such as Fedora 14 and RHEL 5 have good support for Q67 chipset and USB 3.0, but it is still recommended to install official network card drivers to obtain AMT functionality.

Typical troubleshooting and optimization suggestions

Possible causes and solutions for the phenomenon

No display when powered on, CPU power supply not connected/poor memory contact. Check if CN24 is inserted and re plug and unplug the memory

USB 3.0 devices cannot recognize drivers that are not installed or USB 3.0 is disabled in BIOS. Check if USB 3.0 Support=Enabled in BIOS to install drivers

SATA hard drive cannot boot due to incorrect mode settings (such as RAID but not array). Change to AHCI or IDE and check the boot sequence

AMT cannot connect to ME not configured or network not ready. Enter MEBx settings, enable AMT and configure network parameters

COM1 communication abnormal jumper mode inconsistent with BIOS/device. Check JP1-4 combination and confirm external device level type

System fan noise is high. Smart Fan has not been optimized and entered into Hardware Monitor. Set it to Automatic and adjust the start/stop temperature

PCI card interrupt conflict IRQ occupied by onboard device in BIOS, reserved IRQ for ISA, or replaced PCI slot
