dma settings?

[Arron milsom]

hi i was told my dms setting should be on ultra dma 4 or 5 but i only have ultra dma mode 2 ?

i have a 80 pin/wire ide cable (i was told perhaps i had a 40 wire so i checked)

connecting my 2 nec drives to the motherboard

how do i get mode 4 or 5?

"how do i get mode 4 or 5?"

You can't get what your system doesn't support. If the highest setting available is UltraDMA2, then set your drives to UltraDMA2...

mixedupp, DMA is an abbreviation for Direct Memory Access, an access method for external devices where the data transfer is not done by the central processor, but by a small special processor called DMA controller. It uses a procedure called cycle stealing, where the central processor memory access cycles are delayed for very short times to intersperse DMA controller memory access cycles. Some newer, faster DMA modes are called UDMA (Ultra DMA).

The alternative, slow and inefficient data transfer mode is called PIO, Programmed Input-Output, where the central processor transfers data byte for byte or word for word. This requires many processor commands for each data word and therefore causes a high and unwanted processor load.
