A spark. The CPU fan flickered, groaned, and then began a steady, whirring climb. The monitor on the bench glowed blue, then black, and finally—miraculously—displayed a BIOS splash screen. "Gotcha," Leo whispered.
Four SATA II ports colored blue and black. SATA_0 (typically the primary blue port) must be used for your main boot drive to prevent BIOS boot delays.
The board features an LGA 775 socket supporting Core 2 Quad processors up to a 95W TDP. Power is delivered via a 4-pin ATX_12V connector located near the CPU socket, alongside a standard 3-phase voltage regulator module (VRM) layout. 2.

The (often found in Dell Vostro 220, 220s, and some Inspiron systems) is a durable LGA775 board based on the Intel G45 Express Chipset . While older, this board remains a reliable choice for budget retro-computing, office workstations, or home servers. If you are refurbishing or upgrading one, a parts manual PDF is essential for understanding jumper settings, pin layouts, and component limitations.
Located next to the CPU socket. They consist of solid capacitors and chokes to clean the power delivered by the 4-pin ATX_12V connector. 2. Chipset Architecture
Move the jumper cap from pins 1-2 (Default) to pins 2-3 (Clear). Wait 15 seconds. Return the jumper cap to pins 1-2. The monitor on the bench glowed blue, then
Look near the Southbridge chip or the CR2032 coin-cell battery for a 3-pin header labeled CLR_CMOS , CLEAR_CMOS , or RTCRST (Real-Time Clock Reset).
4 x 240-pin DDR2 DIMM slots (Supports Dual Channel DDR2 800/667 MHz, Max 4GB or 8GB depending on BIOS/Revision). Graphics: Integrated Intel GMA X4500 (VGA connector).
