Nice to see people still using Lilo! :D

Lilo is the best...

Open the file in Gimp, and go to Image -> Mode -> Indexed. Now under "Generate Optimum Palette" choose the maximum number of colors to be 255 (Well, I chose 255. Dunno how selecting a different number will affect this. I'm no graphics guru ;) ). Click "Convert" and save. I think that should do it.
Now, the slack.dat file details the dimensional, positional and color parameters of the image (if I'm not wrong). Keep this file open alongside for reference when you are editing the variables. I'm sure it'll help.

Ok, I guess this would help:

Save companion configuration file? (yes or no) [N]:  yes

Save changes to bitmap file? (yes or no) [N]:  yes

Writing output file:  silentwww-640x480.bmp

This is how you should go about if you were to get the parameters in the text file that I linked to in my previous post.

ok cool, so gonna sound dumb again just reading through it, will this work with any image, i.e. how do i know how many columns, row etc will i need or is it just a case of hit an miss

Ok, that output was generated when I used this image. Of course, I scaled it down, and converted it. Using those same variable values on your image might not produce the desired result ( I tried it on my image, and it got spliced). So yes, it is a bit of trial and error, unless you are an expert in graphics. But please don't get exasperated now that you've gotten this far. Also, if you haven't visited the link that aocab provided, I suggest you do. I got all the info that I'm now disseminating from that link.

ah the command is /sbin/lilo -E FILENAME* but now it give me some options to which i am noobishly unsure:

how would i use these options

i went for broke and just write then yes for the next two questions and it still returns with "fatal unsupported bitmap", if there are any gimp masters (wow that sounds a lil wierd) that could give me info an how to make it supported with gimp that may make this easier,
i know some of you could prob do it for me but thats not the point i need to learn lol

thanks again in advance

3) you can use lilo.conf or the bmp file itself to tell lilo the color information (for your text and timer-box)

Using /sbin/lilo -E FILENAME sets the color information in the bmp file.
I did not use that method.

I modified lilo.conf to set the color information.

Code:

man lilo.conf

has all the details on how to set the various settings (and was a little easier for me to understand).

Cheers
HTH

Thanks for clearing it up, aocab :) . But will it work for any image file that I might use?

From what I've read, the image has to be
a 640x480 BMP with 256 colors (or less) and indexed.

tried with the link and the image turns to complete black so gonna spend a fair bit o time with this tryin different settings

(i am happy with lilo's standard setup i.e. where the timer is etc just a shame it's not as simple as just swap the files, lol)

cheers for the help will report back once successsful

I'm not quite sure which image you are referring to...
this is the one I used:
http://www.yzzerdd.net/images/boot/s...40x480x256.bmp

Could you possibly post the image you are trying to use?

Hmm...Something interesting happened after I fed the info into my lilo.conf. I ran lilo, and got this:

Code:

root [ ~ ]# lilo                                                            

Warning: LBA32 addressing assumed

Warning: Unable to determine video adapter in use in the present system.

Warning: Video adapter does not support VESA BIOS extensions needed for

  display of 256 colors.  Boot loader will fall back to TEXT only operation.

Added Slack *

And now there's no bootloader :( Darn.

You should still have a bootloader (those are just warnings)...?
I've gotten those messages before when I had to chroot into the system to run lilo when something went wrong. I would just re-run lilo again as root once I could get back into the system in runlevel 3.

Sorry, I made a typo in the .conf . root got assigned to a non-existent boot image. :). But yes, you're right, those are just warnings. But the interesting bit is that no warnings (other than the LB32 one) were issued when I ran the command from inside a chroot. Not important, I'm sure. Sorry to bother. Thanks for taking time out to reply. :)

EDIT: Really sorry to take the discussion somewhat off the track, but kernel 2.6.35.2 seems to have got serious bug that's causing boot failures. Is there a fix available in 2.6.35.3? I mean it's a pain recompiling now that I compiled 2.6.35.2 a few days back.

(without quotes) to the beginning of lilo.conf.

i too had this but it was when i added "compact" to lilo which is most useful, lba32 is needed for larger sized hard-drives
