[Linux] proting SATA using ATA driver
這一段是說明如何用ata driver改成sata, 照道理來講就是改drivers/ide這一段的code就對了.

Using ataraid results in your partitions being addressed using a /dev/ataraid/d0p1 (etc.) device-naming convention. Note: Support greatly improved circa-2.4.23., m7 h' q. N' D# E

So far (Sept 2004), Promise Fasttrack, HighPoint 37X, Intel ICH5/6, LSI, and SiI 3112A/Medley are supported: http://tienstra4.flatnet.tudelft.nl/~gerte/gen2dmraid/ 8 l+ N9 p0 f ?* r7 M1 R

I'm pretty sure manufacturers' proprietary drivers, where available, are designed to fit the above framework.

; u0 N( ^1 L/ z* o"libata": This is the newer ATA driver set for selected SATA chipsets only, maintained by Jeff Garzik, leveraging the kernel's well-tested SCSI layer. Garzik developed it in the 2.6 kernel series. 2.4 support was available only with a backported patch until libata's inclusion in 2.4.27 and later.& v4 d5 S% i. t6 C
