Description petri.poyhonen 2006-04-19 15:27:41 EDT
Description of problem:
FC5 does not boot after a succesful installation (and a second successful
reinstallation).  I have installed FC5 to two other boxes successfully, this one
fails.  It is Intel Celeron 1.8G with AMIBIOS.

Version-Release number of selected component (if applicable):
GRUB grub-0.97-5.i386.rpm

How reproducible:
Always there.

Steps to Reproduce:
1. Install FC5 from iso cds.
2. Boot
Actual results:
GRUB reports: "GRUB Loading stage 1.5" and "GRUB loading, please wait..."

Expected results:
FC5 should have fired up.

Additional info:
I have tried all the usual tricks:

I have used grub:
root (hd0,0)
setup (hd0)
This completes successfully.  The only difference is that after this GRUB
reports loading Stage 2.

I have used the rescue cd to boot the system and used grub-install /dev/hda.
This completes successfully.

I have also downloaded an older version of grub (the one for FC4, 
grub-0.95-13.i386.rpm), no difference.
I have no downloaded a fresh copy of GRUB grub-0.97-5.i386.rpm and had it
reinstalled.  No help.

I have studied this page
reporting a special behaviour of AMIBIOS, when first boot device was set to DVD
(and boot from HDD was then tried).  I have defined HDD as my first boot device,
no impact.

I can see one anomaly: grub commend find fails to find files.  find vmlinuz
returns "File not found".

I tried this in my other FC5 machine, which boots successfully, the same here. 
grub does not find files (still that machine boots).

More context information:
After booting with rescue cd and chroot /mnt/sysimage ...

grub> root (hd0,1)
 Filesystem type unknown, partition type 0x8e
grub> root (hd0,0)
 Filesystem type is ext2fs, partition type 0x83
grub> find /grub/stage1
grub> find stage1

Error 15: File not found

grub> kernel (hd0,0)/vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00
rhgb quiet
   [Linux-bzImage, setup=0x1e00, size 0x16eb71]
grub> initrd (hd0,0)/initrd-2.6.15-1.2054_FC5.img

Error 28: Selected item cannot fit into memory


As we can see, find works, if file paths are complete.  Grub does not search for
filenames matching the string.

I do not know, whether grub not being able to read (hd0,1), the root partition,
is an anomaly.  Apparently the root partition is perfectly alright after booting
with rescue cd.

What looks like a clear problem is that initrd is not able to process the
ramdisk image.  Would this develop into a problem before we should see the
splash screen ?

My hardware is Compaq Evo D510 e-pc, vintage 2002.

Interesting enough, I became aware of a mother board dip switch:
ON Bootblock protected (default)
OFF Bootblock not protected

I connected this to the OFF stage.  This has hadno visible impact to my failing
attempts to get grub installed and my system fired up.

System does not boot (has never booted).

Boot from rescue cd, chroot /mnt/sysimage.

grub> root (hd0,0)
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... yes
Checking if "/grub/stage2" exists... yes
Checking if "/grub/e2fs_stage1_5" exists... yes
Running "embed /grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded succeeded.
Running "install /grub/stage1 (hd0) (hd0)1+15 p (hd0,0)/grub/stage2
/grub/grub.conf" ... succeeded.

This just confirms that grub installation with commend shell apparently
succeeds, but the system would not boot.

Next I hid stage1.5

# mv /boot/grub/e2fs_stage1_5 /boot/grub/e2fs_stage1_5.bak


grub> root (hd0,0)
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... yes
Checking if "/grub/stage2" exists... yes
Checking if "/grub/e2fs_stage1_5" exists... no
Running "install /grub/stage1 (hd0) /grub/stage2 p /grub/grub.conf" ... succeeded

Now the system should be skipping stage 1.5.
No progress.  System hangs at "Loading stage2 ..."

# grub-install --version
grub-install (GNU GRUB 0.97)

Comment 3 petri.poyhonen 2006-05-06 03:56:22 EDT

I have flashed an update to the bios, AMIBIOS JK.01.01 - JK.01.05
Installed Windows XP, works fine.

Re-installed FC5.
No progress.  Grub continues to hang when loading stage2.

Any ideas, where to go next ?
