+ This is a direct raw access to the media. It is a complex but
+ elegant solution to test and validate the domain of the hardware and
+ perform below the driver data recover if needed. This is the most
+ basic form of media-forensics.

+ If you are unsure, say N here.

depends on BLK_DEV_IDEDMA_PCI
+ help
+ This driver ensures (U)DMA support for Victroy66 SouthBridges for
+ SMsC with Intel NorthBridges. This is an Ultra66 based chipset.
+ The nice thing about it is that you can mix Ultra/DMA/PIO devices
+ and it will handle timing cycles. Since this is an improved
