Hi,

I can successfully use my hard disk when I boot the gentoo livecd, however after installing gentoo onto the disk and trying to boot it, i can't because the kernel doesn't seem to find my SATA controller.

So, I have SATA support built into the kernel, but now I suppose i need to figure out exactly which driver it needs.

I boot the livecd and it seems to load the module for every single SATA device driver possible, here is my lsmod:
Code:

libata seems to have every single SATA driver loaded as a module into it, therefore i'm not sure how to determine which one is actually being used by /dev/sda

anyone know how i can do this?

Thanks!
George

If I had to guess, I would say this one because the "Used by" part is not zero.
Code:
