### 4. Functionality

The DOM‑0015G‑44H‑432 functions as a solid‑state IDE hard disk. It connects directly to a 44‑pin IDE header on a motherboard or controller. The integrated flash controller manages data storage, wear leveling, and error correction transparently to the host system.

Operation Principle:
- The host communicates via standard ATA commands.
- The controller translates these commands into flash operations, managing logical‑to‑physical address mapping.
- ECC hardware corrects single‑bit errors and detects multi‑bit errors.
- Defect block management replaces failing blocks with reserved spares.
- Wear‑leveling algorithm distributes writes evenly across cells.

Typical Applications:
- Embedded industrial controllers
- Data acquisition and measurement systems
- Telecommunications equipment and routers
- Point‑of‑Sale (POS) and kiosk terminals
- Transportation and vehicle computers
- Military and avionics systems
- Set‑top boxes and digital signage
- Portable and hand‑held computers
- Network appliances and gateways

Compatibility:
Operates with any IDE/ATA host controller supporting PIO Mode 0–2. No special drivers required. Recognized by BIOS as a standard hard disk.

### 6. Installation & Setup

Requirements:
- Host system with 44‑pin IDE interface (2.00 mm pitch).
- BIOS support for IDE devices ≥ 1.5 GB.
- Power supply providing +5 V or +3.3 V within tolerance.

Mounting Options:

- Optional adapter for vertical mount or 40‑pin conversion.

Installation Procedure:
1. Power off the system and discharge static electricity (grounded wrist strap recommended).
2. Align pin 1 on the DOM (triangle mark) with pin 1 on the IDE header.
3. Insert the module firmly into the connector using both hands.
4. Configure Master/Slave via JP1 (jumper on = Master, off = Slave).
5. Replace system cover and power on.
6. Enter BIOS setup and enable automatic drive detection (AUTO mode).
7. If manual configuration is required, enter CHS values (C = 3047, H = 16, S = 63).
8. Save settings and reboot.
9. Partition and format the DOM using standard DOS/Windows utilities (FDISK, FORMAT).

Cautions:
- Always align pin 1 correctly to avoid damage.
- Do not force the module into the connector.
- Use both hands to remove the DOM to prevent bending pins.
