So I just got my MP30-AR0 fitted into a case, and I have a few observations and questions. 1) The machine seems to not POST with lopsided memory configurations. For example, I have 6x8GB RDIMMs, and it POSTs with 4 DIMMs in the blue slots, but doesn't POST with the extra 2 DIMMs added to the black slots on banks 0 and 1. Is this expected? 2) u-boot doesn't appear to be responding to keystrokes to interrupt the boot sequence via network KVM console. Am I missing a trick here? How do I interrupt the boot without using a directly connected USB keyboard?
