ECS 945P-A+ is a high performance, enhanced function motherboard designed to support the LGA775 socket Intel Pentium 4/Pentium D processors for high-end business or personal desktop markets.

This ECS 945P-A+ motherboard manual is quite unusual in its layout. I have never seen such layout in a motherboard manual. The first page of the manual is a TUV Certificate and ISO 14001:1996 Certificate, instead of the normal title/name (ECS 945P-A+) of the motherboard model numbers.

As usual, there are four chapters in the manual, covering Introduction to the ECS 945P-A+ motherboard, Installing the motherboard, using BIOS and the software included. There are multi-language translation at the end of the manual too.
