All FW800 boards (with the obvious difference) are not capable of booting Mac OS 9. The Dual-1 GHz MDD has a bus speed of 167 MHz and can take any MDD or FW800 CPU that is designed for the same bus speed. 133 MHz Bus speed: MDD - 867 MHz Dual (1 MB cache on both processors) FW800 - 1.0 GHz single (1 MB cache) 167 MHz Bus speed: MDD - 1.0 GHz Dual (1 MB cache on both processors) MDD - 1.25 GHz Dual (2 MB cache on both processors) FW800 - 1.25 GHz Dual (1 MB cache on both processors) FW800 - 1.42 GHz Dual (2 MB cache on both processor) MDD - 1.25 GHz single (1 MB cache) "education only" 2003 model Hope that helps, Andreas aka Mac User #330250 -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
