[Pocket-linux-micro] Can not prepare the bootloader

[Rocky O. <roc...@gm...>]

Hey,

I downloaded the grup 0.95. export CC="gcc -mcpu=i386" does not give any
warning. But running configure stopped me from going on.

$-------------code begin--------------------------------------$
ronie:/usr/src/grub-0.95# ./configure --host=i386-pc-linux-gnu
--without-curses
configure: WARNING: If you wanted to set the --build type, don't use --host.
    If a cross compiler is detected then cross compile mode will be used.
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... configure: error: newly
created file is older than distributed files!
Check your system clock
$-----------------code end------------------------------------------$

I'm using Debian Etch which is the latest stable version. Can any of you
help me please?

Blessings,
Rocky

Hey,

The 2nd chapter 2.3.1 talks about prepare the book disk media.

I got a blank floppy disk, inserted it in and did the following
$-----code1 begin---------$
ronie:~# dd if=/dev/zero of=/dev/fd0 bs=1k count=1440
dd: writing `/dev/fd0': Input/output error
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.803137 seconds, 0.0 kB/s
$-----code1 end--------$

After that I did mke2fs command as below:
$------------------Code2 begin-------------------$
ronie:~# mke2fs -m0 /dev/fd0
mke2fs 1.40-WIP (14-Nov-2006)

This filesystem will be automatically checked every 26 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
$-------------------code2 end----------------$
After that, I found out I could not mount onto the floppy disk.

$------------------code3 begin-----------------------$
ronie:~# mount /dev/fd0 /mnt
mount: you must specify the filesystem type
ronie:~# mount -t ext2 /dev/fd0 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
$---------------code3 end----------------------------$


$---------------code4 begin-----------------------$
ronie:~# dmesg | tail
Buffer I/O error on device fd0, logical block 0
floppy0: data CRC error: track 1, head 0, sector 7, size 2

end_request: I/O error, dev fd0, sector 6

VFS: Can't find an ext2 filesystem on dev fd0.
$-------------------code4 end-------------------------$

What is the filesystem I should specify for this?

Thanks a lot in advance!

Hello,

I'm new to this list and am trying out pocket linux to learn the linux/gnu
system inside and out (if that's possible).

Anyway, after a week in chapter 2, I still have not successfully go the
bash shell to run. I get a Kernel Panic message that goes on to say "try
passing init=initfile". Well I did this per the instructions.

Does anyone know any reasons why the kernel didn't receive the init= option?

I noticed two others on this list previously had the same problem.

It seems if this is a common problem, once we find the solution, it should
be included in the main tutorial.

Regards,
Bill Branch

[Pocket-linux-micro] Root disk errors

[<ke...@co...>]

After repeated tries, I got the following error(s):

I have no idea how to fix this. :(

[Pocket-linux-micro] Kernel 2.6.7 no init found

[<phi...@fr...>]

Hi all,

   I've been reading the Chapter 2 of your manual and i've made the two f=
irst
diskettes with a new kernel 2.6.7 : downloaded sources from kernel.org,
compiled it without any modules and only with the following options : 386
processor, Floppy disk, RAM disk, Second extended (ext2) filesystem, Cons=
ole on
virtual terminal ;
   Then I couldn't find the boot.b file in my /boot, but i've read that i=
t has
been removed from the lastests lilos (is that right ?), mine is something
ending by "5.8";
   I've filled up the root diskette with the bash binary, symlinked sh an=
d all
...
   On reboot, I write "bootdisk init=3D/bin/sh", the kernel boots and ask=
s me for
the root disk. I change the diskette and then it tries to boot but it giv=
es me
a "Kernel Panic, no init found , try passing ....". Same result if i try
init=3D/bin/bash...

   I've, then, download the two images of diskette from your site and tes=
ted
them with best result : it boots up to the prompt (NORMAL !)

   So, my first question is : can i make the pocket linux with a kernel 2=
.6.7 ?
My second is, do i need to copy more onto the boot floppy ?
May I pass another "init=3D" option to the kernel (or in lilo.conf) ?

Thanks a lot for this guide !!
Keep having fun with Linux

Waiting for any advice to unstuck me :\

Bye

Sounds good.  Can you come up with a short set of instructions for 
building iptables from source and other config files or kernel configs 
that are needed?  It doesn't have to be complete, just a rough starting 
point is fine.
