After install (1.2 i686 stage3) grub causes reboot. the probelem is not a cpu mismatch however. when grub loads I get
Code:

loading grub stage 1.5
grub loading, please wait

then the system reboots. It never gets to the point where it actually brings up the menu. the system is a P3 on a tyan motherboard with a i815 chipset. I setup software raid1 on it which may be part of the problem, but I don't think so because I used the same raidtab and menu.lst off of a system that is booting just fine.
when I installed grub I installed it twice, once to each drive.

just to make sure that it was not a kernel problem I have tried several kernels - gentoo, vanilla, and ac. I have also tried setting the cpu as a pentium classic and pentium II.

i don't think this is a kernel issue, due to the fact that the splash screen isn't coming up, therefore the kernel itself is never initialized.

are you running raid or scsi? it sounds like you are having some sort of hardware issue. is grub installed on the mbr or as a secondary boot loader? also, you didn't get any warnings when installing grub did you? if none of this applies, could you list your hd controller and motherboard model? these will help the people in the forum diagnose your problem a bit better.

The system is has a tyan S2080 Tomcat motherboard with the 815e chipset. http://www.tyan.com/products/html/tomcati815t.html
The two hard drives are ide and are hda and hdb. I would rather they be hda and hdc, but this is the way the computer came and I have not changed it. The computer is actually a penguincomputing relion server http://www.penguincomputing.com/store/relion-105.php


I do get a message when I run grub, but I didn't think any thing of it at the time.
Code:
 
#grub
end_request:I/O error, dev 02:00(floppy), sector0
modprobe: modprobe: Can't locate module block-major-33
modprobe: modprobe: Can't locate module block-major-33
modprobe: modprobe: Can't locate module block-major-34
modprobe: modprobe: Can't locate module block-major-34
grub>

The computer does have a floppy in it, and the rest of the grub install went fine so I forgot about the error until you asked. Just for the heck I it I just tried it with --no-floppy and the first line of the error was not there but the modprobe failure was the same.
EDIT: as stated in first post they are software raid. I installed grub to the mbr of hda and hdb.

hmm, i did a quick search for "block-major-33" and got a couple of posts concerning the errors you received. two reasons were listed as the culprits:

1. the menu.lst file wasn't present when you run grub and
2. the menu.lst file was incorrect

obviously, by my stuttering around, i am not sure what the problem is, but i would suggest rebooting with the cd and running grub again to re-setup the boot sector, and if that doesn't work double check your menu.lst file or post it here so if there is an error present then maybe someone will catch it.

good luck

well I here is my menu.lst, however at this point I am sure the probelm is the whatever is causing the modprobe errors. I read somewhere that the device list was in /usr/src/linux/Documentation/devices.txt, but i cant find any 'block-major-33' in there.
Code:
default 0
timeout 5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=gentoo
root (hd0,0)
kernel /boot/bzImage root=/dev/md2

this is the way I have installed :

boot from cd
load md module
mount md devices
chroot
install grub

what if I was to do it like it was not part of an aray?

boot from cd
mount hd devices
chroot
install grub

would that make any differance? Also do i even need to chroot to install grub?
thanks

well, this explains exactly what the devices are and a possible fix, but the guy the answer was directed to did not get his problem resolved like this. it might be worth a shot. also, do you have splash.xpm.gz in your /boot/grub directory?

thanks for the link. that guy said:
Quote:

You could add in your /etc/modules.conf:
alias char-major-33 off
alias char-major-34 off
alias char-major-8 off

It should solve the problem.



I will give this a try, but I am very curious why the system would think it has more ide chanels, it not like i have an off board ide controller in there. I have dug through the bois several time, I guess I need to look through it again.

SeaPig, is that a typo in your menu.lst file:

Code:
root=/dev/md2


Never heard of md2 before. But I don't know what your setup is. But it should point to where you installed gentoo linux. On my system I put it on hda3.
Where did you put yours?

If that fix talking about using the alias's in /etc/modules.conf works for you, then is it possible you compiled scsi disk support into the kernel when you don't have any scsi disks?

no it is not a typo.
md2 is the raid device

I tried --device-map=
with this as my device map
Code:
(hd0) /dev/hda
(hd1) /dev/hdb

grub did not show any errors when I tried to install it but it still rebooted.

Also how would scsi support matter? Grub has not even loaded the splash screen when it reboots, therefore no kernel has been loaded with or without scsi.
I put a promise controller in it to see if adding a third and fourth ide devices would change any thing but it didn't help.

This is bugging the living fire out of me. I tried to do the install from a 1.2 iso, but not install grub at all, then reboot the system on a 1.4 iso and install grub from it. it did not give any error messages, but it would not boot, just like before.
If I was to _not_ install to the mbr could this help? :?: thx

I got it to work but I cheated. I put the harddrives in another computer and installed grub from there.

I doubt this will shed any light on anything, but I just wanted to mention that I had a hard drive improperly connected the other day (it's the hard drive from my Nomad Jukebox, I had to do some emergency repairs), and grub freaked out and started doing what you're saying. Perhaps some kind of connection got jarred loose? Check your power and IDE/SCSI connections--hell, maybe a dust bunny is doing something nasty. (Seriously. Thought I'd lost a computer once; worked again after a thorough cleaning. :roll: )
