I bought two boards,,i am having problems with drive configurations from the start. Units will not see the A drive or will drop the A drop suddenly. Hard drives will not boot. Norton sees no problem with the drives etc.. Been able to get one loaded with windows...A few minutes later have to re-boot....hard drive cannot be found.. Running 1700+ on one and 2100+ on the other.. 512 megabyte PC2100 DDR Ram... Board swithes are correct with respect to the CPU's 266FSB. Any ideas out there on why I am having so much problem with trying to build these systems
