This means your kernel is unable to access the hard drive.
Possible reasons:
kernel has no support for your HDD controller hardware;
kernel has no support for partition table type used;
the necessary support was built into initrd but it is not loaded.
What feature. Can't see anything on your screenshot. Are you trying to be funny?
Hi...
No, I think he's wanting the same gentoo icon to display on his posts as it does for you. I'm not sure why it's not displaying for the OP, though. I'm guessing the user agent information that astrogeek linked to might lend a clue.
