Thanks guys for the help. I now have a functioning Gentoo System amd64 x86_64 2008.0 at runlevel 3. I'm so Thrilled!!! It took me 6 dry runs through to get there after your assistance and pointers, but I finally Finally FINALLY did it right.
I'm happy to be a new member of the Gentoo Community!
Hello All!

NEW grub PROBLEM (maybe)
Booting from an LG GGW-H2DL SATA BluRay burner on SATA ch6 with the install-x86-minimal-2008.0_beta2.iso CD on an ASUS P5E-VM HDMI motherboard with 4 GB 800 MHz DDR2 ram and an Intel Core 2 Quad CPU Q9450 2.66 GHz cpu, and 5 WD 1TB SATA drives on SATA ch1-5, it works when the bios sets the SATA controllers in IDE mode, but not in AHCI mode. What happens (remember, booting the CD, not the hard drives) in AHCI mode is that grub load enough to display the grub shell command line prompt, but not enough to display the splash screen with the kernel menu. In IDE mode, it boots fine, but IDE is crippled compared to SATA, so I need to run this box in AHCI mode. Here is what lspci shows: | Code: | livecd ~ # lspci

Any ideas what I need to do to get this to boot in AHCI mode? I know I could always do the install in IDE mode, but if I then switch the BIOS SATA mode over to AHCI, will it boot, or does grub have some endemic problem with the STA controller on this box? Can I fix it by recompiling grub some different way, such as is there a way to specify the driver it shoul use? Or does it just loose on te CD/DVD/BluRay drive, but should work on the hard drives? The whole idea of this box is disk perormance in an encrypted RAID setup that handles very large amounts of data, so I sure don't want to leave it in IDE mode. 
Any help will be much appreiated.
Thanks!

As long as you set up AHCI support in your kernel, yes, you can do it that way. I just helped another user here do the same thing.
Blessed be!

Enabling AHCPI In the kernel worked for me with my GRUB issues, which I am proud to report I solved with Erland and Neddy Seagoon's Help.
 I am curious how the Blu-Ray burner works for you. I am interested in getting one and would like more info. Please post as to your success or further issues. Sorry to cross post a bit.
Best

I just want to be clear that grub *NEVER* shows the grub splash screen or the kernel selection menu. I do not think it has tried to boot any kernel at all yet. I seems like it does not finish all the grub stages, but stops in the middle and gives me the grub shell prompt. How is configuring my kernel any particular way going to solve this problem? I never get to the kernel.
BTW My interest in the BluRay drive is for high capacity data recording, not video. I write programs; I don't watch them.

Moriah,
I sounds like you have the missing symlink in /boot/grub that should be menu.lst -> /boot/grub/grub.conf

No, I am booting from the 2008 beta2 minimal livecd, and it boots fine if the interface is configured by the bios to be in ide mode, but it looses in AHCI mode. Same disk, same computer, just the sata controller is set by the bios in a different mode.

I'm having an issue during the install, I'm following the directions from here:
http://www.gentoo.org/doc/en/gentoo-x86-quickinstall.xml#doc_chap2
and this is my first try at Gentoo.
Gentoo (and most other distro's) see my 2 IDE drives first and foremost (/dev/hdc and /dev/hdd ) and then my sata drive (my OS drive) /dev/sda
The doc states
| Quote: | default 0
timeout 10
title Gentoo
root (hd0,0)
kernel /boot/kernel root=/dev/sda3 |
How do i determine the grub id for where root resides?
Starting Grub i'm getting the following error message:
end_request: I/O error, dev fd0, sector 0
doing a "find /boot/grub/stage1 " in grub gives the following (hd2,0)
Is that what should be in my grub.conf file? I'm just trying to be extra careful as to not touch the data on the other devices. Is the fd0 error related to my grub setup or did i do something stupid with my kernel? Any help is appreciated. |

fd0 is the floppy drive, which you likely do not even have nowdays. See the full handbook for more detailed instructions on grub (and everything else about installtion). When you start grub, start is like this:as shown at http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#grub-install-manual
The quickinstall instructions are not for gentoo beginners; they are itended as a quick reminder for those who are already familiar with the process. 
good Luck!

SnowCrashv5,
| Quote: | | "find /boot/grub/stage1 " in grub gives the following (hd2,0) |
shows that grubs stage1 file is on the first partition of the third drive detected by the BIOS. Thats the partition where all the startup files are normally stored (your boot)
Its also what you should use in grub for the splashimage and root (hd.. with a conventional install.
Be aware that grub does not detect your hard drives, the BIOS does. Grub only asks the BIOS what its found.
This means that if you decide to change the boot order, the BIOS may change the hard drive detection order too. BIOSs vary.

crap, thanks guys for the assistance, but it seems i've run into another snag
again my setup: (IDE) hdc, hdd, and (SATA)sda hd(2,0)
following the minimal install instructions after installing grub, i get the grub prompt upon reboot and removal of the cd but selecting Gentoo and booting into the system gets me the following
| Code: |
root (hd2,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/kernel root=/dev/sda3
Error 15: File Not Found
Press any key to continue
|
I double checked when i "livecd linux # cp arch/i386/boot/bzImage /boot/kernel" that the file was indeed there.
also giving my broken grub the command "root" gives the following message:
(hd0,0): Filesystem type is ext2fs, partition type 0x83
Why would it say hd2,0 is grub's root in one place, but not here?
Any ideas? |

SnowCrashv5,
Rather than try keyhole surgery on your system, please post the output of annotated with what each partition is used for and
and your entire grub.conf file.
That should be enough to identify the problem in one go.
Error 15, File Name Not Found really means the path does not exist ... thats any part of the path can be missing.

Due to the security on the box i'm on it's easier to type this out rather than setup ssh, so bare with my manual typing of this.

SnowCrashv5,
Oops its from inside the chroot that I need.
Your post shows a straight forward install.
I suspect the file /boot/kernel does not exist (case of letters is important) or the symlink boot -> .
is missing.

SnowCrashv5,
ls -l would have shown filesizes too but no matter. All your names appear to be in order.
When grub boots and you see on the boot menu, press the 'e' key.
This allows you to edit the in memory copy of grub.conf.
Navigate to the line and change it to read Press the tab key and grub will list all of your drives. Choose one, say hd0 and make the line read Press tab again. Grub will list the partitions.
Repeat for each drive. You will not be able to identify hda and hdb uniquely but they only have one partition, so will give different results to sda.
I would not be surprised to learn that the BIOS has renumbered your sda to be hd0.
When you change it to something that might work, press b to boot.
If its not the BIOS renumbering drives, you have made a typo somewhere that you are not spotting. Thats a huge risk with copy typed information.

Thanks a ton you've been very helpful. The system now boots just fine. Odd though, as /dev/sda1 does not mount into the /boot like it should, to access grub.conf and make the changes for hd0,0 permanent I have to mount it manually. |

|
|
Now that I am compiling my genkernel, is there a way to compile an extra one without modules for a backup or just a second one with modules with a different name such as "kernel-2.6.24-gentoo-r8-recoverey" ??? then the Question for me is how to get that into GRUB...

SnowCrashv5,
Thats normal behaviour for gentoo. If you want /boot to mount automactically, remove the noauto from its /etc/fstab entry.

flacvest,
The kernel name comes from the top of the Makefile in /usr/src/linux.
Make a copy of the entire kernel tree, in the copy change the EXTRAVERSION = at the top of the makefile
Point /usr/src/linux to the new kernel tree then use genkernel normally.
It will put the new kernel into /boot for you.
Now fix grub.conf to your liking

However, this is going over my head, could you break it down into a per command fashion so TOTALLY NEW Gentoo users like me can benefit. I have to be honest, I don't know what you just told me to do!!...

flacvest,
and look around | Code: | /usr/src $ ls -l
total 48
lrwxrwxrwx 1 root root 32 Jun 6 16:48 linux -> /usr/src/linux-2.6.25-gentoo-r4
drwxr-xr-x 21 root root 4096 Jun 13 21:05 linux-2.6.25-gentoo-r4
drwxr-xr-x 21 root root 4096 Jun 19 21:08 linux-2.6.25-gentoo-r5 |
that shows two real kernels and the linux symlink, pointing to one of them.
Make a copy of the kernel tree
| Code: | | cp -r linux-2.6.25-gentoo-r4 linux-2.6.25-gentoo-r4-my-kernel |
edit the name in the makefile | Code: | cd linux-2.6.25-gentoo-r4-my-kernel
nano -w Makefile |
Find the bit (atthe top) that says | Code: | VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 25
EXTRAVERSION = -gentoo-r4
NAME = Funky Weasel is Jiggy wit it |
and append something to the EXTRAVERSION =
Say, change it to | Code: | | EXTRAVERSION = -gentoo-r4-flacvest |
Use the command to select your new kernel, that sets the symlink to point to it.
Now you can use genkernel to make your new kernel. Its name will be taken from the Makefile.

I named the kernel copy "linux-2.6.24-gentoo-r8-flacvest" and tried to use the command:
eselect set linux-2.6.24-gentoo-r8-flacvest
... and recieved an error message like so:
!!! Error: Can't load module set
Killed
... what steps should I take now??
Confused, and apparently 99% of the way there,

flacvest,
Do | Code: | cd /usr/src/
rm linux
ln -s /usr/src/linux-2.6.24-gentoo-r8-flacvest linux
ls -l |
which is what the eselect would have done
Make sure the linux -> /usr/src/linux-2.6.24-gentoo-r8-flacvest appears in cyan (pale bule)

|
|
when I do an 'ls' command from "/usr/src" I see linux in cyan, and when i input the command 'eselect kernel show' it states: Current kernel symlink:
/usr/src/linux-2.6.24-gentoo-r8-flacvest
... Is there a way to install this a a "backup" for GRUB so that I can boot to a command prompt to fix my system without the chroot affair and live cd??
Also was just the link "linux" supposed to be cyan, or should "/usr/src/linux-2.6.24-gentoo-r8-flacvest" be also cyan (I'm assuming that "linux" appears cyan due to it being a symlink??)
At this point do go through installing the kernel to GRUB somehow (explicit instructions would help) or am I ready to perform a "shutdown -hr now" and expect the system to boot into GDM which is set to the default runlevel.
OH!, Neddy, the biggest reason I wanted a quote unquote "backup" kernel is for when I screw up things like my xorg.conf or GDM theme and need a command line. How do I achieve that??
I appreciate your patience with me,
