Where can i find an l-i945e manual? help me pls.

This is a motherboard for a Lenovo/IBM device. As such, it is a factory-installed mainboard and not sold direct to the consumer over the counter. As such, there is no manual provided for this mainboard, only for the machines it is installed in.

I'm unsure of your OS and processor socket type, but these are the most relevant drivers for your particular motherboard from the Zebronics site.

http://zebronics.info/downloads/motherboard/945_775_and_945_plus_L_775/

If you download the listed audio.zip file, extract it and try to install them and find they don't work-- try removing the "945_775_and_945_plus_L_775/" without the quotes from the link above and try the other listed model variations of your i945 motherboard.

Hope this helps!

There are ribbon connectors for this. There are pins on the edge of the mobo that correspond to the cables. Check online for a manual.

Support Intel Pentium 4 641, 640, 631, 630, 620, 521, Celeron D

Why don't you look at the support section of the Gigabyte website? That is where you will need to go to download it anyway.
