I get the following error after configuring the grub boot loader, and rebooting
| Quote: |
Root-NFS: No NFS server availabvle, giving up
VFS: Unable to mount root fs via NFS, trying floopy
VFS: Insert root floppy and press ENTER
`VFS: Cannot open root device "sda3" or unknown-block(2,0)
Please append a correct "Root=" boot option
Kernel panic - not syncing: VFS: Unable to mount rot fs on unknown-block(2,0)

This is my grub.conf file

default 0
timeout 30
title=Gentoo Linux 2.6.12-r10
root (hd0,0)
kernel /boot/kernel-2.6.12-gentoo-r10 root=/dev/sda3

device.map

I have a SATA hard drive, I set it up just like the gentoo handbook except i replaced hda with sda.
Ideas? This is getting a little frustrating (I've never delved into the lower level parts of linux before), but I don't want to give up... this is the last phase before I have a working system.
Thank you!

Did you enable SATA support in your kernel?
You will find SATA support under Device Drivers --> SCSI --> Low-Level Drivers

After looking around, it appears I may not have installed SATA drivers for the kernel.
However, I don't know which one to compile.... using lsmod, I turn up this line:
Not sure where to go...
I have a Seagate barracuda (i think thats the product name? its seagate, regardless) 7200RPM SATA hard drive on an Nvidia nForce 4 motherboard.

Do lspci you should find a line that looks somthing like this (it is what I have on my PC):
| Code: | | 00:08.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev f3) |
Once you find of which one you have, just
| Code: | | cd /usr/src/linux && make menuconfig |
Then scroll to device drivers,
SCSI devices,
Low-Level Drivers,
Choose accordingly.
If you need help, just post the output of lspci.
EDIT: I just noticed that you probably have the same controller as I have.
Choose Serial ATA (SATA) support with a (*), and then NVIDIA SATA support also with (*). |

Did you emerge dhcpcd? If not you should do that. If that does not do the trick (after you restart ofcourse), then post the output of
