Where to find initrd .img and kernel parameter
 

Hi folks,

Installation of LFS 6.1 has been finished. Now I'm going to edit /etc/grub.conf of the FC3 Host making dual boot at starting the PC.

I found LFS Kernel = lfskernel-2.6.11.12

Under
The path to the kernel image........
On 8.3. Linux-2.6.11.12
http://www.linuxfromscratch.org/lfs/...08/kernel.html

Where can I find its initrd .img and the kernel parameter.

TIA

There is no initrd image for LFS by default.

Here's what an LFS entry looks like:
title LFS 6.1
root (hd0,3)
kernel /boot/lfskernel-2.6.11.12 root=/dev/hda4

On the kernel line you can add something like:
vga=795
for a framebuffer that's 1280x1024 (but you have to enable framebuffer support in the kernel).

Hi kjordan,

Tks for your advice.

Hereunder is /etc/grub.conf of FC3 HostIf I understand your advice correctly the new /etc/grub.conf of FC3 Host should look like;/dev/hda6 is for LFS. Is "root (hd0,5)" correct?

If I'm wrong, please correct me. Tks

Noted.

On configuring LFS kernel, I selected all items.

Yes, hd(0,5) is correct as long as you have a folder called boot on there and there is a kernel image named lfskernel-2.6.11.12 in there.

Wow, that must have been tedious...it would have been easier just to find out what modules you needed.

Hi kjordan,

Finally I finished the building of LFS 6.1. Having edited FC3 Host /etc/grub.con manually and with command "shutdown -r now" to reboot the PC.

LFS 6.1 booted but can't login.

local.localdomain login:
(I suppose it is LFS login)

Tried
Login = root/LFS/lls
Password = lfs_password/host_password

Always mentioning "Login incorrect"

On Host's console I can login LFS with
$ su - lfs
password = lfs_password
lfs~:#

Repeated following steps and met with failure;

1)
8.3. Linux-2.6.11.12

and
8.4. Making the LFS System Bootable

Recompiled kernel and then ran

2)

grub> root (hd0,5) [Enter]

Error 21: Selected disk does not exist

grub> setup (hd0) [Enter]

Error 12: Invalid device requested

grub> root

Pressing Tab no function

3)
root:/sources/linux-2.6.11.12# shutdown -r now

LFS kernel not found on the boot loader. I have to start FC3 Host to edit /etc/grub.conf manually.

Kindly advise. TIA

LFS 6.1 is now running
 

Hi kjordan,

Finally LFS 6.1 is up running:

After booting it prompted
localhost.localdomain login: root
password:
-bash-3.0# ls /boot/Only a black screen displayed because no desktop package installed. Editor -vim

SOLUTION
=========

Copied Root password of FC3 Host on /etc/shadow to /mnt/lfs/etc/shadow

Lot of tks for your assistance in the past.

Well, the real root password before you overwrote it with your FC3 password was what you would have set in the shadow chapter when it prompted you to "passwd root", although I suppose if you wanted the passwords the same copying the shadow file is alright too. Good luck and have fun with BLFS ;)

Hi kjordan,

There was root password enty on /mnt/lfs/etc/shadow file. It did not work. It was the same password as lfs-user on FC3 Host. I copied it from /etc/shadow to /mnt/lfs/etc/shadow making it as the root password of LFS 6.1 then it worked. It differed from the root password of the Host.

Up to now I still could not have a breakthroungh on creating a rescure floppy according to the instruction.

Re colour depth and framebuffer support
 

Hi kjordan,

Further questions : - re "vga=795"

and

"for a framebuffer that's 1280x1024 (but you have to enable framebuffer support in the kernel)."

If I want 1024 x 768, 24 bit colour depth, how to set it

On compiling kernel - "make menuconfig" under which item I can find "framebuffer support" to get it enabled.

TIA

vga=0x318 for 1024x768 16M colors

Device Drivers -> Graphics Support -> Console Display Driver Support

Enable Video mode selection support and Framebuffer console support and compiled-in fonts and vga 8x8 and 8x16 fonts.

Hi kjordan,

Noted with thanks
