A while back we posted about a hiccup with the Intel Desktop Board DQ45EK where we could not get an OS installed (previous post) with 4GB of RAM (2x 2GB) installed.
After a _lot_ of troubleshooting, it turned out to be the BIOS. We backed the BIOS off and were greeted with an OS load and the type of system response times we would expect from that configuration.
Intel has released a new version of the BIOS, version 0115. The problematic version was 0111 with the downgraded version we used being 0109.
We will begin testing the setup to see if the new BIOS indeed resolves the problem.
