Kernel Config?

How do I enable DMA in my kernel. Ive set the SATA drivers as requested, but my kernel does nto support the DMA option. I need to configure my kernel. I am running Fedora 5 on a Thinkpad T43 with GNOME.

SATA disk does not use DMA to transfer data, only PATA drives needs DMA.
This is one reason why SATA disks are better than PATA.

Anyway, DMA is set on PATA disks with the program hdparm.
