I am answering my own post in case someone else comes looking for an answer to the same question. The reason for a beep code of 10 short beeps is that there is no video card. I made the mistake of thinking because it had the Intel C226 chipset and video connectors that it didn’t need a CPU with graphic capability. I robbed a video card from a nearby PC and the beep code disappeared and the server booted normally. Perhaps they will put that beep code in the next revision of the on-line manual.
