UEFI drive recognition

linuxbird · 06-30-2012, 12:15 PM

Can anyone point me to somewhere I can read up or understand how linux recognizes harddrives, when running on a UEFI based system?

I'm getting a kernel running, but I don't recognize any harddrives. (Tested them, with different boot package and they are there.)

So I'm looking for pointers on what module handles them or if they are otherwise handled differently when UEFI is involved. Thanks.

I read all of those, except one on GRUB2, prior to making my posting. The first one, I have read several times, because it had other pieces of the puzzle.

I am trying to find the mechanism in the target kernel, for detecting and then making available a disk drive. My next stop is looking at the drivers.
