Overview

The Intel Desktop Board covered in this manual targets legacy value or business desktop systems. It supports Intel Pentium 4 / Celeron D / Core 2 Duo (depending on specific chipset: 915G/945G/946GZ/GL). The codes “21 B6 E1 E2” often appear on PCB silkscreen or BIOS labels for factory identification.

Problem 1: System turns on for 1 second, then off (Fan spins then stops)

Diagnosis: Short circuit or VRM failure. Manual Solution:

1. Remove the board from the case (test on a cardboard box).
2. Disconnect the 4-pin/8-pin CPU power connector (ATX12V). If the board stays on but beeps, the CPU VRM is shorted.
3. Check for bulging capacitors near the CPU. The E1/E2 marking sometimes indicates "solid polymer caps" – but if you see vented electrolytics, replace them.
