ADLINK NuPRO-E320 motherboard deployment and tuning guide

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).
