ROCKY-4786EVG

iEi ROCKY-4786EVG Full Sized PICMG 1.0 CPU Board Repair, Replacement & Sales

The iEi ROCKY-4786EVG is a full sized PICMG 1.0 CPU board built for industrial automation, OEM embedded systems, machine control platforms, and legacy industrial computers that require dependable performance and long-term serviceability.

This board supports Intel Socket 478 processors including Intel Pentium 4 and Intel Celeron D, with support for up to 800MHz front-side bus (FSB). It is well suited for legacy industrial applications that rely on stable x86 architecture and compatibility with full-size PICMG 1.0 passive backplane systems.

The ROCKY-4786EVG includes a robust industrial I/O feature set with VGA, LAN, Gigabit Ethernet (GbE), USB 2.0, and Serial ATA (SATA), making it a practical option for maintaining, repairing, or replacing existing industrial computing systems without a full platform redesign.

At SoftTouch Technologies, we provide iEi ROCKY-4786EVG repair, replacement, testing, procurement, and integration support for customers maintaining active and obsolete industrial systems. Whether you need a tested replacement PICMG 1.0 board, board-level repair, or assistance confirming backplane, processor, storage, and I/O compatibility, we can help.

iEi ROCKY-4786EVG Overview

The ROCKY-4786EVG is designed for industrial environments that require a full-size PICMG 1.0 single board computer with dependable processor support, storage flexibility, and reliable network connectivity.

Key platform characteristics include:

• iEi ROCKY-4786EVG full sized PICMG 1.0 CPU board
• Full-size PICMG 1.0 form factor
• Intel Socket 478 processor support
• Supports Intel Pentium 4 and Intel Celeron D processors
• Up to 800MHz FSB
• VGA display output
• LAN / Gigabit Ethernet (GbE)
• USB 2.0 support
• Serial ATA (SATA) support
• Designed for industrial passive backplane systems

Because many PICMG 1.0 systems depend on exact backplane compatibility, BIOS behavior, processor support, and stable legacy software environments, repairing the original board or sourcing an exact tested replacement is often the safest and most cost-effective solution.

Why Repair or Replace the ROCKY-4786EVG Instead of the Entire System?

Many systems built around the iEi ROCKY-4786EVG rely on validated passive backplane architecture, exact BIOS behavior, custom I/O integration, and stable legacy operating environments. Replacing the entire system can require backplane changes, software revalidation, or mechanical redesign. In many cases, the best option is to repair the original board or source a tested exact replacement that preserves the current platform architecture.

Bench Testing & Functional Validation

Before shipment or after repair, we can perform functional validation such as:

• Power rail verification
• CPU and memory POST testing
• Backplane startup and slot compatibility checks
• VGA display output verification
• LAN / GbE network testing
• USB 2.0 functional checks
• SATA detection and boot validation
• Warm reboot / cold reboot stability checks
• Extended soak testing when required
