Intel G41 Express (Eaglelake-G) + ICH7 North/Southbridge combination.

LGA 775, supporting Intel Core 2 Quad, Core 2 Duo, Pentium, and Celeron processors.

Even when the PC is "off," the board receives +5VSB from the power supply. The schematic shows:

The H-IG41-UATX Rev 1.1 schematic is a complex document that reveals the intricate connections between various components on the motherboard. The schematic is divided into several sections, each representing a specific area of the board:

This is the most complex part of the schematic. The Rev 1.1 board uses a 3-phase or 4-phase PWM controller (commonly an ISL6312 or RT8802A). The schematic reveals:

The VID0 - VID6 lines connect from the CPU socket directly to the PWM controller. If these lines are open or shorted, the CPU will not receive its correct core voltage.

Never assume a component is good because it looks fine. The schematic provides net names (e.g., +12V_CPU , PWR_GOOD , H_RESET# ). Always verify continuity on these nets.

By combining these resources with the H-IG41-UATX Rev 1.1 schematic, users can gain a deeper understanding of the motherboard and unlock its full potential.

PicBackMan does exactly what it's supposed to. It's quick and efficient. It runs unobtrusively in the background and has done an excellent job of uploading more than 300GB of photos to 2 different services. After having lost a lot of personal memories to a hard drive crash, it's nice to know that my photos are safe in 2 different places.

LOVE this program! Works better than ANY other program out there that I have found to upload thousands of pictures WITH SUB-FOLDERS to SmugMug! Thank you so much for what you do! :) #happycustomer

I pointed PicBackMan at a directory structure, and next time I looked - all the photos had uploaded! Pretty cool. I use SmugMug and while I really like it, the process of creating directories in is pretty laborious when you need to make 80+ at a time. This was a breeze. Thank you!
