ADLINK NuPRO-A301 Industrial Motherboard Troubleshooting Manual

The driver for NuPRO-A301 is located on the accompanying CD and is installed in the following order: chipset driver → display driver → network card driver → ISA driver → audio driver (optional).

6.1 Chipset Driver (Intel 945G)

Path: Chipset infins_autol.zip, after installation, make the operating system recognize the functions of ICH7 South Bridge and 945GC North Bridge.

6.2 Display Driver (Intel GMA 950)

Path: VGA win2k_xp14324.zip, supports DirectX 9, maximum shared 224MB of video memory, resolution up to 2048 × 1536@75Hz .

6.3 Network Card Driver (Intel 82574L)

Path: Ethernet PRO2KXP-v13_1_2.rar, supports Wake On LAN.

6.4 ISA Driver (IT8888 PCI to ISA Bridge)

Due to Windows not automatically recognizing the bridge, manual installation is required:

Open Device Manager and find 'Other PCI Bridge Devices'.

Right click to update the driver and select 'Install from list or specified location'.

Point to the CD ISA directory and install ite-INF.

After installation, ISA bus devices can only work normally (note: IT8888 does not support DMA, only PIO).

6.5 Audio Driver (optional IP-ALCS20)

Path: Audio WDM-R203. zip. Before installation, AC97 Audio (Integrated Peripherals → Onboard Device) needs to be enabled in the BIOS.

Chapter 7: Quick Troubleshooting Table for Common Malfunctions

Troubleshooting steps for possible causes of fault phenomena

No response when powered on, fan not running, ATX 12V not connected, power failure or JP1 setting error. Check if CN4 is plugged in tightly and test power output; If using AT power supply, check if JP1 is short circuited

Power on but no display. CPU not installed, poor memory contact, graphics card conflict. Reinstall CPU and memory, clear CMOS (JP2), check Init Display First setting

The system repeatedly restarts due to poor heat dissipation and insufficient power supply. Monitor the PC Health temperature and replace the high-power power supply

The operating system cannot find the hard drive (SATA) On Chip Serial ATA mode setting error. Change to Enhanced or Combined mode and check the SATA cable

Serial communication garbled or no data. COM2 jumper mode does not match the device. Configure JPB2 correctly based on device type (RS-232/422/485)

USB keyboard is invalid under DOS. Legacy USB is not turned on. Enable USB keyboard support in Onboard Device

ISA card cannot work. ISA driver is not installed or there is an IRQ conflict. Install ISA driver and reserve IRQ for ISA in PnP/PCI configuration

Check if Watch Dog Timer Select is enabled in BIOS and run sample code to test if the watchdog does not trigger reset, incorrect configuration or application program is not feeding the dog

No audio output, AC97 Audio not enabled or daughter card not installed. Check if the BIOS is enabled and confirm that the IP-ALCS20 daughter card is securely connected
