But I have just managed to compile SATA support in kernel 2.4.25 and wanted to share my experience. It might be useful for others trying something similar. After some googling I found that there exists "libata" patches for earlier kernels. You can find them at ftp://ftp.kernel.org/pub/linux/kernel/people/jgarzik/libata/old/. Now all you need to do is take a clean source tree of the 2.4.xx kernel , apply the patch , enable SCSI support and in the "low level SCSI drivers" choose your appropriate SATA chipset while configuring the kernel. In my case, I used kernel 2.4.25 with the 2.4.25-libata16.patch.bz2 patch. Shourya > ciao, Marc > -- Kernelnewbies: Help each other learn about the Linux kernel.
