A client bought an ECS RS400-A motherboard/Pentium D processor as a set on sale (Fry's Electronics) and asked me to build it into a system. 98, 98SE, 2000 Pro and XP SP2 Pro installs load appropriate drivers but all hang at the point where setup starts windows. I have been told by collegues that use of the LGA 775 slot means that the motherboard can take either; however, I read other places (like Tom's Hardware) where motherboards require a special boot sequence to determine whether to boot single or dual core.
The ECS website does not specifically state support for Pentium D (only Pentium 4) and all of the reviews do not address it.
Has anyone successfully built a system with a Pentium D or do you know that they are in fact not interchangeable?
Take care and have a good day.
