To change this, it's necessary to mess with the values in kernel/boot/preboot.inc and reassemble kernel.asm
I believe setting display_atboot to 2 will do the trick.
Another option would be to decrease the value of preboot_timeout.
has already done a special branch for this: viewtopic.php?f=34&t=63&start=90
An old version is available here: http://ftp.kolibrios.org/users/CleverMouse/kolibri-cfg/
New version can be defined as auto-build (you just need to setup auto-build script for this).
Readme file (sadly only in Russian): http://websvn.kolibrios.org/filedetails ... loader.txt
You should edit config.ini
and make timeout=0
(then blue screen will be skipped).
