### 4. Functionality

The DOM‑0015G‑40H‑030 operates as a solid‑state IDE drive. Internally, a PQI flash controller manages NAND flash arrays through advanced algorithms:

- Defect‑Block Management: Automatically replaces failed blocks with reserved spares to maintain data integrity.
- Wear‑Leveling Algorithm: Distributes write/erase cycles evenly across all blocks to extend flash lifetime.
- ECC (Error Correction Code): Corrects single‑bit and detects double‑bit errors per 256 bytes, ensuring reliable data transfer.
- Power‑Loss Protection: If power is interrupted during programming, only the last 512 bytes are affected; data integrity is preserved on next power‑up.

Use Cases & Applications:
- Embedded industrial controllers and PLCs
- Data acquisition and measurement systems
- Telecommunications and networking equipment (routers, gateways, kiosks)
- Transportation and vehicle systems
- Military and avionics electronics
- POS terminals, ticketing, and vending machines
- Compact PCs, thin clients, and set‑top boxes

Compatibility:
Operates with any IDE/ATA host supporting 40‑pin connectors. Recognized by BIOS as a standard HDD. Compatible with all major operating systems supporting IDE storage.

Configuration Procedure:
1. Power off the system and ground yourself to prevent ESD.

3. Insert the module firmly into the IDE socket.
4. Connect the 4‑pin power cable if the host does not supply +5 V on pin 20.
5. Configure Master/Slave mode:
- 40‑pin DOM: Use power connector color coding (white = Master, blue = Slave) or ring plug method (ring inserted = Master, removed = Slave).
- 44‑pin DOM variants: Use JP1 jumper (On = Master, Off = Slave).
6. Power on the system and enter BIOS setup. Select AUTO drive detection or enter manual CHS values (Cyl = 3047, Head = 16, Sector = 63 for 1.5 GB).
7. Save settings and reboot.
8. Partition and format the DOM using standard DOS/OS utilities (FDISK, FORMAT).
