DVMT Mode Select: Fixed, DVMT, and Both (dynamic video memory allocation) can be selected.

IGD Graphics Mode Select: 32/64/128MB of system memory can be allocated to integrated graphics cards.

South Bridge Configuration:

USB Functions: You can disable or select the number of USB ports (2/4/6/8).

USB 2.0 Controller: Enable/disable USB 2.0 functionality.

Legacy USB Support: It is recommended to enable (to support USB keyboard/mouse under DOS).

Audio Controller: Enable/disable HD Audio (required when using DBAudio2).

Onboard LAN BootROM: Enable/disable PXE network boot.

Resume On LAN1: Enable LAN wake-up function.

5. Security and Exit

Security: Administrator and user passwords can be set (clear CMOS to remove).

Exit: Supports saving changes and exiting, discarding changes, loading Optimal default values (performance first) or Failed Safe default values (stability first).

Driver installation process (Windows XP/7)

Suggest installing in order:

Intel Rapid Storage Technology driver (if using AHCI/RAID):

Press F6 to load the floppy disk driver (or use nLite integration) during Windows XP installation.

Windows 7 does not require preloading.

Chipset driver (Intel G41): Run infist_autol-9.2.0.1030.exe.

Display driver (GMA X4500): Run winxp_14425.exe (Windows XP) or the corresponding Windows 7 version.

Network card driver (Intel 82574L): Run PROWin32.exe.

Audio driver (optional DBAudio2): Run setup. exe (Audio Controller needs to be enabled in BIOS first).

All drivers are located on the accompanying driver CD or ADLINK official website.

Programming Example of Watchdog Timer (WDT)

The WDT of NuPRO-E315 is implemented through Winbond W83627DHG-A Super I/O. Programming steps (example code summary):

Unlock Super I/O: Write 0x87 sequence to port 0x2E.

Select logical device 8: Write 0x07 to 0x2E, and then write 0x08 to 0x2F.

Activate WDT: Write from 0x30 to 0x2E, then from 0x01 to 0x2F.

Set the counting unit: write 0x5F to 0x2E, then write 0x00 (seconds) or 0x08 (minutes) to 0x2F.

Set timeout value: Write 0x6F to 0x2E, and then write timeout value (0x01~0xFF) to 0x2F.

Refresh counter: Repeat step 5 to write the same timeout value to 'feed the dog'.

The system will automatically reset after timeout.

System resource allocation and interrupt routing

Memory mapping (brief):

640KB~768KB: Video buffer.

768KB~896KB: PCI expansion ROM (including VGA BIOS and LAN PXE ROM).

1MB or more: System BIOS and APIC space.

DMA channel: channels 0/1/2 are open, and channel 3 is reserved for parallel ports (shared with floppy drives).

I/O address (typical):

COM1=3F8h（IRQ4），COM2=2F8h（IRQ3）

LPT1=378h（IRQ7）

COM3~6: C80h/C88h/C90h/C98h (IRQ configurable)

IRQ routing (APIC mode): PCIe root port and onboard devices (USB, SATA, network card, graphics card) are assigned IRQ 16~23. If there is a conflict when inserting a third-party PCI card, the PIRQ routing can be manually adjusted in the BIOS (refer to Table B-6).

Common troubleshooting and engineering recommendations

Possible causes and solutions for the fault phenomenon

Power on, no display. CPU not installed/uneven pressure in heat sink/memory not properly plugged in. Check CPU installation, re plug and unplug memory, and use recommended heat sink

The heat sink caused the PCB to bend. The push pin heat sink was replaced with a screw fixed heat sink with a backplate

SATA hard drive cannot recognize SATA mode settings (IDE/AHCI/RAID). Configure SATA as in BIOS and adjust it to matching mode. Install the corresponding driver

COM1 communication abnormal jumper mode inconsistent with external device. Adjust JP1~JP4 according to actual application (232/422/485)

USB keyboard is invalid under DOS. Legacy USB Support is not enabled. Enable Legacy USB Support in BIOS

The system cannot wake up (LAN) Resume On LAN1 is not enabled. Enable Resume On LAN1 in BIOS

The watchdog did not trigger a reset, WDT was not activated, or the timeout value was set improperly. Check the activation and feeding logic in the code to ensure that the timeout value is valid

Remote access cannot connect due to mismatched serial port parameters or Remote Access not enabled. Check if Remote Access is enabled in BIOS and the baud rate matches the terminal

After AC power failure, it does not automatically start. Restore on AC Power Loss is set to Power Off and changed to Power On or Last State

Reference for heat dissipation and power consumption:

Core ™ 2 Quad Q9400 has a full load of approximately 75W (total power consumption), dual core E8400 has approximately 63W, and Pentium E5300 has approximately 50W.

The chassis needs to ensure an ambient temperature of 0-60 ℃ and a good air duct. It is recommended to use a 3U or larger size heat sink.
