To understand nsc6001 , you must first understand .
At first glance, it looks like a typo or a corrupted driver. It is neither. The ACPI NSC6001 device is a specific hardware signature for a family of legacy Embedded Controllers (ECs) manufactured by (later acquired by Winbond, then Nuvoton). For modern operating systems, this identifier signals a requirement for a specific set of I/O communication protocols.
| Error in Event Viewer | Likely Cause | Fix | |-----------------------|--------------|------| | ACPI: NSC6001 failed to start. Error 0x10 | Device cannot find assigned I/O resources. | Check BIOS for PNP OS setting. Set to "Yes". | | The ACPI EC device did not respond within timeout | The EC is stuck in a loop or powered off. | Hard reset (unplug AC + remove CMOS battery). | | NSC6001: Device has been blocked from loading | Driver Signature Enforcement or Hyper-V isolation. | Disable Memory Integrity (Core Isolation) in Windows Security. | acpi nsc6001
Drivers are available for Windows XP, Vista, 7, 8, and 10. Where to Find Drivers
Boards like the (2D/3D series) and Soekris net5501 use the Geode LX. In their coreboot or legacy BIOS, the DSDT exports NSC6001 . Users control LEDs, watchdog triggers, or external relays via /sys/class/gpio/ . To understand nsc6001 , you must first understand
The NSC6001 exposes up to 64 GPIO pins, grouped into banks (A, B, C, D), each controlled by a set of 32-bit registers. The key registers (relative to a base I/O address BASE ) are:
The NSC6001 typically uses I/O ports 0x62 and 0x66 (standard EC command/status ports) or 0x68 / 0x6C . If another legacy device claims these ports, the ACPI driver will fail to start. The ACPI NSC6001 device is a specific hardware
The hardware ID corresponds to the National Semiconductor IrDA Fast Infrared Port , a legacy component found in many older laptops and mobile workstations. This device was used for short-range wireless data exchange between computers, printers, and PDAs before technologies like Bluetooth and Wi-Fi became universal. What is the ACPI\NSC6001 Device?
Device (GPIO) Name (_HID, "NSC6001") // Hardware ID Name (_CID, "NSC6001") // Compatible ID Name (_CRS, ResourceTemplate () IO (Decode16, 0x6100, 0x6100, 0x01, 0x10) // I/O port range IRQ (Edge, ActiveHigh, Shared) 11 // IRQ line ) Name (_DSD, Package () ... ) // Device-Specific Data (optional)
The ACPI NSC6001 represents an evolutionary bridge between legacy x86 I/O and ACPI-driven plug-and-play. Its limitations highlight several enduring lessons:
