 |
|
| I am installing gentoo on a new Asus P5E X38 with the intel ICH9R bridge. I am using the 2007 minimal cd and I can not see my sata hard drive installed on the board. I have a 3ware 8006 2lp raid controller and it is seeing that volume as /dev/sda. I have the sata in the bios set as IDE and nor Raid. So if any body has some suggestions I would greatly appreciate it. |

The kernel on the gentoo live cd is quite old. You could try if it works using any other live cd, for example knoppix or ubuntu - if it does, you can use that live cd to install gentoo.

| Try http://www.sysresccd.org/Main_Page, it is small, can be put on a flash drive (liveUSB) or CD (liveCD), and is actually based on gentoo! Remember, you can install Gentoo from almost any liveCD. I tried the system rescue liveUSB when I had a problem similar to yours. |

Yep, your hardware is new, so the minimal cd doesn't support your hardware. SystemRescueCD is really a Gentoo minimal CD with extra tools, so there is no extra command to install Gentoo with it.
Just boot with it, and think that this is a minimal Gentoo CD. |

Any of the mentioned live distros will work nicely. Just follow these instructions and you'll be just fine.  (And, no, you don't have to use Knoppix  ).

Is there a third setting of "ACHI"? If so, try that. |

| Alright I put it in AHCI and I was able to see the drive. I installed Gentoo on it and now when I boot I get the dreaded kernel panic. It tells me that VFS unable to mount root fs on unknown block (8,3). I have followed the hot to written on the ICH7 and ICH8 chipsets that were out there, but it appears many people are having issues with the ICH9R chipest. I have Tried both the gentoo-sources and the 2.6.24.1 kernel and no so luck. If anybody has gotten Gentoo to work on a ICH9R with the X38 chipset I would greatly appreciate some advice. |

csalsb,
| Code: | | mount root fs on unknown block (8,3) |
is /dev/sda3.
However, if you have managed to compile your kernel with both SATA and PATA support for your hard drive, PATA wins and your root will be /dev/hda3.
The message can also mean that the kernel is missing support for your root filesystem.
To test, at the grub splash screen press 'e' and edit your (real_)root=/dev/sda3 to read /dev/hda3 and contine the boot.
You will get a fsck error message if that works, as fsck cannoy find /dev/sda3 either (from your /etc/fstab)
Give the root password then run | Code: | | mount -o remount,rw / |
to get read/write access to root.
You can now fix your kernel from inside your own system.
If you want to get your system up reasonably normally, edit /etc/fstab and /boot/grub/grub.conf to use the /dev/hda nodes but be aware it will be very slow until you fix it properly as you will have no DMA, which is a 10x to 20x hdd speed improvement.

| Thanks for the help I was ablt to get it fixed by selecting in the Sata section of the kernel the AHCI driver. I got rid of the intel chipset support all together and had just ahci and jmicrom pata. This did the trick. I appreciate all the advice. |

Glad you got the issue taken care of. Please add [SOLVED] to the original title, so that others can easily find your solution if they have a similar problem.
