ADLINK NuPRO-770 Full length SBC Configuration and Maintenance

Key BIOS Settings Points

Although the manual does not provide a complete BIOS screenshot, based on the Award BIOS interface, the following points are worth noting:

Chipset options: The video shared memory size can be configured (1-11 MB), and it is recommended to allocate it reasonably according to the display resolution requirements (such as allocating 8 MB for 1024 × 768 × 16bpp).

Power Management: If Wake On LAN or modem wake-up is required, enable the corresponding event in the "Power Management Setup" and ensure that the+5VSB power supply capability of the ATX power supply is sufficient (Intel 82559 wake-up current is approximately 100mA).

PCI configuration: For users using traditional ISA cards, specific IRQs can be set to "Legacy ISA" in the "PNP/PCI Configuration" to avoid PCI device occupancy.

Integrated peripherals: The onboard VGA or LAN can be disabled separately (if an external graphics card or network card is required) to save interrupt resources.

CPU temperature alarm: The critical temperature of the CPU (such as 70 ° C) can be set in "PC Health" or similar options, and the system will automatically shut down or alarm when exceeded.

Driver installation process

1. Intel 810 chipset INF installation (key steps)

Windows 95/98/2000 must first install the chipset INF file to correctly identify the internal devices of i82810 (including AGP, USB, LPC, etc.). Run NuPRO Drivers Chipset Intel Win9x2k Disk1 SETUP.EXE from the CD, follow the prompts to complete and restart.

2. VGA driver installation

Windows 98/95/2000: Run NuPRO Drivers VGA V810 Win9x Graphics SETUP.EXE (Win2k corresponds to the Win2k directory).

Windows NT 4.0: Run NuPRO Drivers VGA V810 Wt40 Graphics SETUP.EXE (requires NT Service Pack 5 or later to be installed first).

3. Intel 82559 LAN driver

Windows 2000/98: Manually update drivers through Device Manager, point to the path NuPRO Drivers LAN 82559 on the CD, and select oemsetup.inf or net82557.inf.

Windows NT: You need to first create a driver floppy disk (run NuPRO Drivers LAN 82559 Makedisk MakediskNT), and then select "Install from Disk" in the network installation.

4. Hardware monitoring tools

Hardware Doctor is located in NuPRO Drivers HWDoctor WIN98 (or WINNT), and executing Hwm-98.exe can start real-time monitoring.

Typical troubleshooting and maintenance recommendations

The system cannot start (black screen):

Check if the CPU is fully inserted into Socket-370 (pay attention to foolproof notches).

Confirm that the memory module is PC-100 SDRAM and is securely installed (it is recommended to test with a single module first).

Clear CMOS (if JP2 is present, short-circuit the corresponding pin to restore default).

Check if JP4/JP5 matches the CPU external frequency (66MHz corresponds to 66/100 automatic mode).

COM2 cannot work on RS-422/485:

Confirm that all JP1 to JP3 are set correctly according to the table (especially note that JP3 is 5-6 when RS-485).

Check if the external terminal resistors match (RS-422/485 long wires require terminal resistors).

IDE device cannot recognize or UDMA is invalid:

Confirm that "IDE Primary/Secondary Master/Slave UDMA" is set to Auto in the BIOS.

Check if the 40 pin IDE cable supports UDMA/66 (requires 80 core cable).

The onboard network card is not working (only 770):

Confirm that the Onboard LAN is set to Enabled in the BIOS.

Check if the LED indicator light of the RJ-45 connector is normal (upper green=100Mbps, lower yellow=link/activity).

If using Wake On LAN, confirm that the+5VSB current of the ATX power supply is sufficient.

Watchdog does not trigger reset:

Confirm that the timeout value is set correctly (non-zero).

Check if the automatic reload caused by keyboard/mouse interruption never times out (this feature can be disabled).

Confirm that the relevant interrupts are not blocked in the BIOS.

Abnormal system temperature or failure to display fan speed:

Check if the CPU heat sink is in good contact and if the FN1 fan is connected and of 3-pin speed measurement type.

If the external system temperature sensor is not connected, the corresponding monitoring item can be disabled in Hardware Doctor to avoid false alarms.
