Message-ID: Date: 16 May 89 15:45:03 GMT Sender: news@sun.soe.clarkson.edu Reply-To: cline@sun.soe.clarkson.edu (Marshall Cline) Distribution: comp.os.minix Organization: Clarkson University, Postdam NY Lines: 25 Two questions: (1) I recently read in the Minix textbook (Prentice Hall) about a DMA caveat that AST had discovered. It had something to do with wrapping around 64K barriers as I recall. Anyway, I can't find the specifics now that a friend needs them :-( QUESTION: Does anyone know the information to which I am refering? Page#? (2) AST mentioned that there is minimal documentation for using DMA. QUESTION: Does anyone know a pointer to more detailed doc on DMA?
