Dear Intel Support,
I installed Ubuntu OS server edition in a computer system with Intel desktop board D945GCCR for years, and it has been working well. Can it say that this Intel desktop board support Ubuntu OS server edition?
Qiubosu, it is hard to say that this board supports that operating system, but since you have years using it without problems, you may continue doing it.
Based on the fact that we do not have support for any Linux flavor, if you have any question regarding this combination, you would need to forward your inquiry to Linux* Ubuntu distribution support community for further assistance http://www.ubuntu.com/community
This specific Intel® Desktop Board supports only the following operating system http://www.intel.com/support/motherboards/desktop/sb/CS-008326.htm
