Boot Instructions for the Remix User
|
||
|
|
|
||
|
|
To give some boot-time instructions to the user create an isolinux.txt file in image/isolinux, for example:
|
||
|
|
|
||
|
|
************************************************************************
|
||
|
|
|
||
|
|
This is an Ubuntu Remix Live CD.
|
||
|
|
|
||
|
|
For the default live system, enter "live". To run memtest86+, enter "memtest"
|
||
|
|
|
||
|
|
************************************************************************
|
||
|
|
|
||
|
|
|
||
|
|
Splash Screen
|
||
|
|
|
||
|
|
A graphic can be displayed at boot time, but it is optional.
|
||
|
|
The example text above requires a special character along with
|
||
|
|
the file name of the splash image (splash.rle).
|
||
|
|
To create that character, do the following use the following command:
|
||
|
|
|
||
|
|
printf "\x18" >emptyfile
|
||
|
|
|
||
|
|
and then edit the emptyfile with any text editor. Add the file name just next to the
|
||
|
|
first character and add the text you want to display at boot time beneath it and save the file as "isolinux.txt"
|
||
|
|
|
||
|
|
To create the splash.rle file, create an image 480 pixels wide. Convert it to 15 colours,
|
||
|
|
indexed (perhaps using GIMP) and "Save As" to change the ending to .bmp which converts the
|
||
|
|
image to a bitmap format.
|
||
|
|
|
||
|
|
|
||
|
|
---- IN GIMP DO THE FOLLOWING ----
|
||
|
|
1. Open an image.
|
||
|
|
2. Scake it to 480 and make sure hight is bound to it.
|
||
|
|
3. Go to image > mode > indexed (Set minimum number of colors to 15 if you have issues down he road Otherwise leave it as is.)
|
||
|
|
5. Save As a BMP. When doing so set compatibility options on for 'Do not write color space information'
|
||
|
|
|
||
|
|
|
||
|
|
Then install the "netpbm" and 'syslinux-utils' packages and run
|
||
|
|
|
||
|
|
1. bmptoppm splash.bmp > splash.ppm
|
||
|
|
2. ppmtolss16 '#ffffff=7' < splash.ppm > splash.rle
