NextAnswers hardware.442 says: "A DMA request is sometimes "jammed" in the internal disk bus at power-on. You can ignore the EC81 message and continue normally; the error code does not impair system performance. This problem has been observed once in a great while on a few machines. Typing [Alt][Cmd]-* is the easiest way to clear it. If the problem persists, call the NeXT service department. For a list of all the ROM error codes, see NextAnswer hardware.475, or /NextLibrary/Documentation/NeXT/SysRefMan/17_ROM.wn." -Dave
