Grub, Scsi, and problems.

aim nano · Posted: Fri Jan 20, 2006 6:26 pm Post subject: Grub, Scsi, and problems.

I installed Gentoo last night. I followed the Handbook to a T. Everything seemed to go smoothly right on through configuring my bootloader (GRUB) and even the reboot. So my system boots the first time...GRUB loads (I have my timeout set to 5). After 5 seconds, it selects my default (the only choice) Gentoo. Screen goes black for a half a sec...then back to the grub loader screen. Gentoo still highlighted...but nothing. I can hit enter again and it'll go black then come back to the GRUB screen again. Any help?

Is it possible that grub is failing to find your kernel? Can you post your grub.conf?

I used the generic one in the handbook...making a change for the SCSI drive and timeout.

default 0

timeout 5

splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.14-r5
root (hd0,0)
kernel /boot/kernel-2.6.14-gentoo-r5 root=/dev/sda3

In that case this is odd. Obviously the bios has found grub, and grub has found its config files. Does /boot/kernel-2.6.14-gentoo-r5 exist?

You can play with the grub boot entry by selecting it, and hitting either e or o (I can't remember which). The right key from the main menu will show you your root & kernel command lines. Navigate to the kernel line and then try editing it - grub supports bash completion which I find very helpful when I can't remember the name of my kernel

Hi.

Please post the output of fdisk -l and ls -l /boot. If you do it from the live-cd, please do instead ls -l /mnt/gentoo/boot.

Two other things I'm looking at. Here is my grub.conf:
default 0

timeout 5

splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.14-r5
root (hd0,0)
kernel /boot/kernel-2.6.14-gentoo-r5 root=/dev/sda3

during my installation I ran the command
cp arch/i386/boot/bzImage /boot/linux-2.6.14-gentoo-r5

should my kernel be /boot/kernel... or /boot/linux...

Also do I need the /boot. I read elsewhere that /boot is understood and I should just have /grub/splash.xpm.gz and kernel /kernel... (or linux) whichever it is...

Well, it seems you forgot to copy your kernel to /boot.
Boot with your live-cd, mount the partitions and chroot, then do the following:

I booted with live-cd, mounted, chrooted then:

jmbsvicetto · kernel-2.6.14.-gentoo.r5

Please post the output of ls -l /mnt/gentoo/boot again.

aim nano · Posted: Fri Jan 20, 2006 10:46 pm Post subject:

Pardon that was just a typo.

It actually reads
System.map-2.6.14-gentoo-r5
and
kernel-2.6.14-gentoo-r5

I was copying the code by hand...but it's right in my ls -l /mnt/gentoo/boot

Well, in that case please try to use the GRUB command line. There you should type the following:

What I did.

What processor do you have?

aim nano · Posted: Sat Jan 21, 2006 1:33 am Post subject:

Pentium II (Klamath)

My make.conf is nonexistent.

I know i made it during the installation. I may be in the wrong place.

Other random files in /etc:

hosts
protocols
cron files
bash
hotplug
services
security
terminfo
networks
nanorc
filesystems, etc, etc

would i have needed to chroot?

all i did was mount like:

mount /dev/sd3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot

then:

nano -w /etc/make.conf (blank)

aim nano: My problem (as you posted in my thread) is the exact same. Down to the freezing on grub CLI.

Hope we can get this sorted out.

Start from scratch? Or just recompile a new kernal?

I'm pretty sure you just need to fix that option and compile a new kernel.

I'm pretty much starting over so,
I just ran the command

/mnt/cdrom/stages

to make sure my cd rom was mounted (suggested in handbook even though i already knew it was mounted)

and i get these stages

stage3-athlon-xp
stage3-i686
stage3-pentium3
stage3-pentium4
stage3-x86

Now this is maybe why I got confused with my make.conf because the only options close to mine is pentium3.

So maybe I assumed I'd have to use that throughout my installation to maintain uniformity.

the next step is:
tar xvjpf /mnt/cdrom/stages/stage3-<subarch>-2005.1-r1.tar.bz2

which subarchitecture do I use for a pentium2?

My install is almost the same as your's, this is my grub.conf

default 0
timeout 30
splashimage-(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.14
root (hd0,0)
kernel /boot/linux-2.6.14-gentoo-r5 root=/dev/sda3

when I compiled my kernel it saved it as linux and not kernel so after you compile and cp over to /boot do a ls and note what your kernel is called and edit grub to same.
