Close. When they say ``J18 & J19 are master 0'' it really means that only one of the slots can be used for a master card, so you can put a master in slot J18 OR J19 AND J20. Thus you could use J18 & J20 OR J19 & J20 for the 2842's. Good luck.... -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc. Reliable computers for FreeBSD
