messages and logo at booting

wk · 08-31-2003, 05:51 PM

At the beginning KNOPPIX displays logo in framebuffer (file logo.16 from boot.img) and
message: "Welcome to KNOPPIX Linux live on CD" (or something like this). I have two questions:
1. why the image displays even if I delete file logo.16?
2. How to change the message "Welcome..."?

thanks in advance

I think you are confusing two different things.

the file logo.16 is displayed to the screen at the very begining of the boot proccess, and it is a large rectangle taking most of your screen, with the bottom saying something like :
KNOPPIX 06/06/2003 www.knopper.com

boot:

(IIRC

)
now, after that screen is gone you see a penguin sitting at the top of the screen, and under it the text : "Welcome to the KNOPPIX live Linux-On-CD" (with KNOPPIX shown in various colors).
this text is diplayed by the file linuxrc, wich is found inside miniroot.gz inside boot.img
the image is no-where to be found, and I suspect is embedded inside the kernel (can any of you confirm or deny that?)

I can confirm that...

OK, that was it (I thought that boot image is the penguin). But what about this line "Welcome..." - is miniroot.gz a normal gzip file? Can I unpack it, edit the file and gzip it again? (well, a tried that and I got kernel panic, what I did wrong? Is it possible to change that line?)

thanks,

unzip it, then mount it (it's an ext2 I think)
inside it edit the file linuxrc, umount miniroot, and re-gzip it

It seems like I'm too lame even to mount a file...:
# mount -o loop=/dev/loop0 -t ext2 /my/working/directory/miniroot /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
or too many mounted file systems

But: 1) fs i OK, in KNOPPIX documentation, everywhere in the web, I found this
command with ext2 specified; 2) there are no special options (except loop, but
this is mandatory in this case); 3) there are no other loop mounted file systems (but I tried
also on other loops: 0..7);
4) I have no clue what this problem with bad superblock means, maybe this is the point.

Maybe some of you had the same problem?

Here's what I did...

Log onto your Linux box as root, then...

1.) gunzip miniroot.gz
2.) mount miniroot /pathtowherethe/minirootfileis -t ext2 -o loop=/dev/loop0
3.) vi linuxrc and then make your modfications
4.) umount mroot
5.) gzip -9 miniroot
stick it back into boot.img and off you go.....

It worked perfectly for me. Hope that helps.
