2300C works standalone, but not in Duo Dock (M7779) or Duo Dock Plus (M1585). I get a Sad Mac face with error codes 000000F and 00000001. I get the same error with both docks. My "Fix Your Own Mac" book says that means software exception and bus error. I don't know what that means. The previous owner of the Duo Dock said it worked with a Duo 230. The 2300C manual says it needs a Duo Dock Plus. Can anyone help me? I'm using a Mac M1212 monitor with both Duo Docks and neither one has a hard drive installed. __________________________________ Do you Yahoo!? SBC Yahoo!
