A method for direct memory access (DMA) data transfer is adapted for a computer system having a microprocessor, a chipset, a memory with a physical region description (PRD) table and a DMA engine. In the method, a first group of PRD entries including at least two PRD entries of the PRD table by the DMA engine is fetched during a single PRD entry fetching cycle. Accordingly, a first group of blocks of data of the memory corresponding to the first group of PRD entries is accessed in sequence
