Thanks to everyone who offered help. The UP1000 boots via AlphaBIOS, not srm or arc. For thos people who suggested that it was a ram problem, the same problem occured when I took the ram out. Alpha Processor has told me that it is a dud board, and I'll be getting it replaced. Thanks again Robert __________________________________________________ Do You Yahoo!?
