you mean DMA..
I thought DMA was just a transfer mode of ATAPI. Someone correct me if I'm wrong.

ATA is the interface standard, DMA is the way data is transfered. As the name, Direct Memory Access says, it goes directly from the drive to the memory, over PCI bus, instead of through CPU.

but which one gives u they faster transfer rate?

i guess best transfer rate is when DMA is checked for ATA drive properties.
i dig Seagates, YMMV

DMA driver is already in win98se
then why give ATA driver?

All depending on the chipset in use, of course. e.g. IAA (Intel Application Accelerator) is necessary for correct UDMA-100 operation on Intel 8xx chipsets. Via has the 4-in-1 driverset. Depending on the OS different parts of the via-set need to be installed.

ATA = Atachment

Ata is as it says the atachment type cable connected between the motherboard and the HD, and the best one is the Ultra ata 133 > with a 80 wire cable ... It's only 40 pin but every pin has 2 wire ... just in case if one is brocken ... at least is there another one.

In win 98 Se you can choose the Hd or Cd rom transfert mode (DMA enabled), but in win 2000 and Xp is automatically recognized.
