Release Found: Red Hat Enterprise Linux 5.1

The Intel DQ35JO and DQ35MP systems require the specific parameter pci=nommconf to be passed to the kernel to boot Red Hat Enterprise Linux 5.1. The following command should be entered at the boot prompt after booting from installation media:

boot: linux pci=nommconf

The parameter is not required with Red Hat Enterprise Linux 5.2 or newer.
