 Posted: Sun Apr 13, 2008 1:12 am Post subject: Problem booting a VIA C7 motherboard [Solved] |
 |
|
I am trying to boot my manually configured kernel on a fresh install. The mtherboard is a Via C7 motherboard JETWAY J7F2WE1G2EOLFLV RT.
My problem is that on bot I get a message indicating:
| Quote: |
No such file directory while trying to open /dev/ROOT
/dev/ROOT
The superblock could not be read or does not describe a correct file system
etcetera ...........
|
I am able to enter my root password and do the following:
1) e2fsck /dev/sda3 - no errors found
2) read-only access to everything I can think of
I can access the drive (read only), so I do not think I have a driver selection issue.
After that Any help would be appreciated

well,you have to mount gentoo using a livecd,edit /etc/fstab,comment out(put a "#" infront) those lines which asks for LABEL= values.
then add a new line with
| Code: | | /dev/urgentoopartition(/) / ext3 noatime 0 1 |
then add swap:-
| Code: | | /dev/urswap none swap sw 0 0 |
if u make a /boot partition,add it too as:-
| Code: | | #/dev/urbootpartnno. /boot ext3 noauto,noatime 1 2 |
you should definitely read gentoo handbook 
see the one for me:-
| Code: | # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#/dev/BOOT /boot ext2 noauto,noatime 1 2
#/dev/ROOT / ext3 noatime 0 1
#/dev/SWAP none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
/dev/sdb6 / ext3 noauto,noatime 0 1
/dev/sdb11 none swap sw 0 0 |
that's it!

I should have been more clear in my initial post.
I have already built the kernel, created /etc/fstab, installed and configured grub. As far as I can tell the configuration of grub and the /etc/fstab is correct. I am still suspicious about the kernel.
On reboot to the manually configured kernel on /dev/sda1, I can not boot to /dev/ROOT found in /etc/fstab. This happens after a noticeable amount of hard drive activity. When this happens I am able to enter some kind of maintenance mode (after entering the root password) where
| Code: |
e2fsck /dev/sda3 -f
|
does not report any errors
my /etc/fstab (the chrooted one with comments removed) is:
| Code: |
/dev/BOOT /boot ext2 noauto,noatime 1 2
/dev/ROOT / ext3 noatime 0 1
/dev/SWAP none swap sw 0 0
/dev/cdrom /mnt/cdrom audo noauto,ro 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
Since e2fsck does not distinguish between ext2 and ext3, I have also tried
| Code: |
/dev/BOOT /boot ext2 noauto,noatime 1 2
/dev/ROOT / ext2 noatime 0 1
/dev/SWAP none swap sw 0 0
/dev/cdrom /mnt/cdrom audo noauto,ro 0 0
shm
|
my partitions are as follows:
/dev/sda1 - ext2 (boot) - has grub, kernel, memtest 86
/dev/sda2 - swap
/dev/sda3 - ext3 (/) - has the system files and other stuff
Since this is a manual configuration of the kernel, I suspect that I may be missing some configuration option of the kernel.
If more information would be appropriate (like the contents of .config) please let me know. |

What praka123 is trying to tell you is that /dev/ROOT /dev/BOOT and /dev/SWAP are just placeholders.
You need to edit /etc/fstab and replace these with valid device names, such as /dev/sda3 |
