Code:

A suggestion at grub select c type set root=(hd then tab what is the output

nothing.there's no such a command

spiky0011 · 11-16-2011, 01:56 PM

reboot then when grub screen appears hit c that will give grub prompt type

Code:

set root=(hd

then press tab key that will show drive options hd.0 hd,1 etc

devilboy09 · 11-16-2011, 02:03 PM

Code:

set root=(hd

there are two options hd0 and hd1

spiky0011 · 11-16-2011, 02:08 PM

so we all agree "put me right if i,m wrong " that grub can see 2nd harddrive.

I'm not too sure if this will help, but have you done a clean hard reboot since making changes? If not, power down and leave for 30 seconds, then power up.

The reason I ask is that you have CONFIG_KEXEC=y, which is used for fast rebooting with the same kernel. Whilst if the kernel changes it should reload, I'm wondering if KEXEC is rebooting to the kernel held in memory, rather than the modified kernel. It shouldn't, but strange things happen sometimes.

spiky0011 · 11-16-2011, 02:27 PM

I would like to see the out put of. "Reboot" grub prompt again then c

Code:

set root=(hd1.msdos

then tab

and i have two options:msdos1 and msdos2

Hi,

I've just had a look at your .config file and changed a lot of settings. Try the following after saving the included .config file:

Code:

# from your host, as root:
cp /where/you/stored/downloaded/.config /mnt/lfs/usr/src/.config

# from inside the chrooted environment:
cd /usr/src/linux-3.1
make mrproper
cp /usr/src/.config .config
make menuconfig
# no changes are needed, exit and possibly safe (the make menuconfig is a precaution step)
make
make modules_install

cp -v arch/x86/boot/bzImage /boot/vmlinuz-3.1-lfs-7.0
cp -v System.map /boot/System.map-3.1
cp -v .config /boot/config-3.1

Exit the chrooted environment and re-boot, select LFS 7.0 and keep your fingers crossed!

New kernel .config: http://pastebin.com/QYGsytTf

Hope this helps.

http://hotfile.com/dl/135229647/9a2b...ocess.png.html

my machine just stuck and i can't use my keyboard!!!

Hi,

Either:
- There's another kernel option that is incorrect (I focussed on drives, not other stuff).
- Something is wrong with your /etc/inttab file.

But without knowing what has scrolled off-screen I cannot be sure. We probably need to see that info as well.

If I look at the /etc/inittab file you posted in post #29 (_if_ that one is still relevant!!): It does look OK.

why it's trying to enter in runlevel 3,4 and 5.it should enter in runlevel 1 because there is no X. am i right?

devilboy09 · 11-16-2011, 03:40 PM

Nope.

LFS starts in runlevel 3 (command mode).

runlevel 5 would start X (not done in LFS, BLFS has that part).

runlevel 1 is a safe mode where almost nothing is started (bare essentials)
runlevel 2 is like 1, but network is included
runlevel 4 isn't used in (B)LFS
runlevel 6 restarts the system

Hope this clears things up.

Please use pastebin!! hotfile limits downloads (told you this before).
