Steps for installing CPU and memory
2.1 CPU Installation (LGA1150)
The manual provides a detailed description of the CPU installation process, with key points including:
Anti static operation: It is necessary to operate on an anti-static workstation and wear a grounding wristband.
Unlocking mechanism: Press down the locking arm and push it outwards to disengage from the fixed buckle, lift the load pressure plate, and remove the plastic protective cover.
Alignment direction: Align the golden triangle mark on the CPU with the Pin 1 indicator angle on the socket, and align the grooves on both sides with the socket positioning key.
Vertical placement: Place the CPU vertically into the socket, do not apply force, only install in one direction.
Locking: Lower the load pressure plate, ensure that its leading edge is engaged under the screw, then press down on the locking arm and snap back the buckle.
Attention: Before installation, be sure to disconnect all power sources and avoid touching the socket contacts, otherwise it may result in the warranty being invalidated.
2.2 Radiators and Fans
The CPU must be equipped with a dedicated heat sink and fan (FAN1 interface), otherwise it may damage the motherboard or CPU. The manual emphasizes that if the installation steps are inconsistent with the instructions provided with the radiator, the latter shall prevail. Apply thermal grease evenly and connect the fan cable to the motherboard FAN1 (CPU fan) or FAN2 (system fan) interface.
2.3 Memory Installation
The motherboard provides 2 240 pin DDR3 DIMM slots and supports 1/2/4/8GB non ECC buffer free memory.
To enable dual channel mode, the capacity of both channels must be equal (DIMM1=DIMM2). It is recommended to use memory modules of the same brand, model, and CAS latency.
During installation, align the notch of the memory module with the anti mistake protrusion of the slot and insert it vertically until the two side buckles automatically lock.

Layout of onboard I/O and connectors
The I/O of NuPRO-E42 is distributed on the front and rear panels as well as the onboard pin layout. The manual provides detailed location diagrams (Figure 1-4). The key connectors are as follows:

Key BIOS settings
BIOS (AMI UEFI) is accessed through the DEL key, and F7 is the boot menu. The following are the configurations that need to be focused on during deployment:
4.1 Advanced
CPU configuration: Can enable/disable hyper threading, virtualization (VT-x), execution disable bit; Adjust the core number of activities.
SATA mode: Supports IDE, AHCI, and RAID. If using RAID 0/1/5/10, it must be set as RAID here, and after POST, press Ctrl+I to enter the Intel RST configuration interface.
USB configuration: Enable Legacy USB Support to support USB keyboard and mouse under DOS; USB 3.0 supports turning on/off; XHCI/EHCI Hand off is used for compatibility with older operating systems.
Super I/O configuration: Configure the I/O address and IRQ of each serial port.
Hardware monitoring: It can view CPU/system temperature, voltage, fan speed, and set FAN1 intelligent speed regulation (automatic/manual/full speed), supporting temperature threshold and PWM slope.
AMT configuration: Intel AMT can be enabled/disabled, and BIOS and OS watchdog timeout (in seconds) can be set.
Serial console redirection: Supports terminal redirection for COM0/COM1, used for remote management, can set baud rate, data bit, stop bit, flow control, etc.
4.2 Chipset
Graphics and Memory Bridge: Optional initial display device (IGD/PEG/PCI), set IGD shared memory size (32M~128M), supports multiple displays.
PCH bridge configuration: PCIe ports (x1 or x4 mode), PCIe sub decoding, etc. can be configured.

4.3 Security
Administrator password and user password can be set, with a password length of 3-20 characters.
Support TPM security devices (TPM Support needs to be enabled).
4.4 Boot
Can set boot timeout, NumLock status, quiet start (displaying OEM logo), and quick start (skipping some POST).
Adjust the startup priority to support UEFI and Legacy modes.
4.5 Exit
Save/discard changes, restore default, save as user default, boot from EFI Shell, etc.
Programming Practice of Watchdog Timer (WDT)
The watchdog of NuPRO-E42 is based on the IT8783 Super I/O chip and can be programmed through LPC registers. Appendix B of the manual provides complete C language example code (located in the NuPRO NuPRO-E42 WDT directory on the accompanying DVD).
Core operating procedures:
Enter IT8783 configuration mode (write specific sequence to 0x2E or 0x4E).
Select logical device 7 (WDT device).
Set timeout value (in seconds, 1-255) and write the count value through register 0x73.
Enable WDT output (reset the system through KBRST signal), or disable it.
Exit configuration mode.
Typical applications:
After the system starts, call IT8783_WDTRun (count, PLEDFlag), where count is the timeout seconds, and PLEDFlag controls whether to map the onboard LED to the WDT status indication.
The application needs to periodically "feed the dog" (reset the counter) to the WDT register, otherwise timeout will trigger a system reset.
This feature is particularly critical for unmanned devices and can effectively prevent production interruptions caused by software deadlocks.

Driver installation sequence
The manual recommends a Windows 7 64 bit environment with drivers located in a specific directory on the accompanying DVD. Install them in the following order:
Chipset driver (Chipset NuPRO NuPRO-E42 Chipset) - recognizes Q87 chipset components.
Display driver (Display NuPRO NuPRO-E42 VGA 64 Bit) - Install Intel HD Graphics driver.
Ethernet driver (Ethernet NuPRO NuPRO-E42 Ethernet Windows 64) - Install I217LM and I211-AT drivers.
Management Engine Driver (Others ME-Driver) - used for AMT functionality.
USB 3.0 driver (USB3) - Ensure that the USB 3.0 port is working properly.
Intel Rapid Storage Technology (Others RST) - If RAID or AHCI is used, F6 can be preloaded during system installation.
Attention: Before installing Windows, if RAID mode is required, the RST driver must be loaded during the installation process (F6 method).
System resource and interrupt optimization
Appendix C of the manual provides a detailed list of memory mapping, DMA channels, I/O ports, IRQ allocation (PIC and APIC modes), and PCI configuration space mapping. When there is a hardware conflict or the expansion card cannot be recognized, the following points can be referred to:
IRQ sharing: Many PCIe devices share IRQ (for example, PCIe ports 0~7 can be routed to IRQ 16~23). If you insert a high load card, you can adjust the PIRQ routing in the BIOS or disable unused onboard devices (such as serial ports and parallel ports) to release IRQ.
PCI Interrupt Routing: The table shows that PCI slots 0-4 are mapped to PIRQ A~H. If an interrupt storm occurs, you can try replacing the expansion card slot.
I/O port conflict: Avoid overlapping I/O addresses between onboard serial ports (3F8/2F8, etc.) and expansion cards.
Power consumption reference
The manual provides actual power consumption data (Core i7-4770S configuration):
Idle state: Approximately 10.5W (12V 0.38A+5V 0.68A+3.3V 0.78A).
CPU full load: about 85W (mainly 12V 6.5A).
S3/Sleep: Approximately 0.6~0.8W.
Suggested power supply: At least 350W ATX power supply to ensure sufficient power supply for PCIe expansion cards and hard drives.
Common troubleshooting checklist
Possible causes and solutions for the phenomenon
Power on, no display, CPU not installed properly or memory contact poor. Reinstall the CPU and check if the memory is securely plugged in; Clear CMOS
Check the WDT configuration when the system repeatedly restarts and the watchdog times out or the power supply is insufficient; Replace with a higher power supply
Serial communication failure COM1 mode switch (SW13) setting error check dip switch to ensure compatibility with device (RS-232/422/485)
USB 3.0 does not recognize that the driver is not installed or USB 3.0 is disabled in the BIOS to install USB 3.0 drivers; Enable XHCI in BIOS
RAID array cannot create SATA mode. If not set to RAID, enter BIOS and modify SATA mode to RAID. After restarting, press Ctrl+I
Check the FAN1 speed and clean the radiator if there is a malfunction of the automatic frequency reduction fan due to high temperature or dust accumulation on the heat sink; Adjust the speed control curve of the fan
PCIe expansion card unresponsive to resource conflicts or BIOS port configuration errors attempting to replace slot; Adjust PCIe Port Gen Speed in Chipset
