Set IDE Primary Master PIO/UDMA to Auto in BIOS.
If using a large hard drive (>8.4GB), LBA mode needs to be enabled.
Q5: LCD display abnormality or screen blur?
Confirm that the JP1 power supply voltage (3.3V/5V) matches the panel.
Select the correct resolution and color (Panel-1~16) for Panel Type in BIOS.
Check if the 40 pin ribbon cable connection is secure and if the signal cable is too long.
Q6: Hardware monitoring software cannot detect fan speed?
The fan must be 3-wire (with speed measurement output).
Enable fan monitoring in the Configuration of Hardware Doctor.
Driver and software support
The NuPRO-598 CD includes:
Intel PIIX Bus Master IDE driver (Windows 95/98) - enhances UDMA performance.
C&T 69000 VGA driver (Windows 95/98/NT 4.0) - supports CRT/LCD synchronous display.
Intel 82559 LAN driver (Windows 98/NT/2000, NetWare, Linux, etc.) - provides diagnostic tools.
Hardware Doctor (Hardware Monitoring).
For modern operating systems such as Windows XP or Linux, it may be necessary to look for third-party compatible drivers, but it is recommended to maintain stable operation on the original system (such as Win98).
Maintenance and upgrade suggestions
Heat dissipation: Socket7 CPU generates a large amount of heat (especially K6-3), it is necessary to use an active cooling fan and regularly clean the dust.
Battery: The onboard CR2032 CMOS battery has a lifespan of approximately 5-8 years. If the time is reset or the BIOS is lost, it needs to be replaced in a timely manner.
Electrolytic capacitor: The board manufactured in 2001 has been over 20 years old, and the power filter capacitor may have aged and bulged. If there is abnormal restart or voltage fluctuation, it is recommended to replace it with a capacitor of the same specification.
Backup BIOS: Use the Award Flash tool to backup the current BIOS to prevent flashing failures.
Spare parts: If planning for long-term operation, it is recommended to stock up on CPUs of the same model (such as Pentium MMX 233) and memory.
