FreeBSD Splash Screen
Created: 02/21/2006
General Information
FreeBSD allows for the configuration of a splash screen to replace the text displayed while booting. Often an image is preferred over plain text. Adding a splash screen will not eliminate the text that would have been displayed while booting. This text is always available by running dmesg.
Requirements

root access

This requires either a bitmap or a ZSOFT PCX image file.  The image must be 256 colors (8 bit) or less and must be a supported resolution.  By default the largest resolution supported is 320x200.  However, if the vesa module is loaded, other resolutions up to 1024x768 may be possible, though 256 colors remains the maximum.
Configuration
This guide will demonstrate the configuration changes that must be made to loader that are required for a splash screen.  These changes can be made in the /etc/loader.conf or in a /etc/loader.conf.local file.  This guide will use /etc/loader.conf.local for all examples.
Using a Bitmap Image
Create /boot/loader.conf.local and add a line to it that will load the vesa kernel module.  This can be done as root in one command:
#
echo 'vesa_load="YES"' >> /boot/loader.conf.local
Add a second line that will load the bitmap kernel module.
#
echo 'bitmap_load="YES"' >> /boot/loader.conf.local
Add a third line that will configure the bitmap image to be loaded at start up.
#
echo 'splash_bmp_load="YES"' >> /boot/loader.conf.local
By default /boot/kernel/splash.bmp is the image that will be loaded.  Copy the image to /boot/kernel/splash.bmp or this setting can be changed by specifying the path to the bitmap file using bitmap_name.
#
cp /path/to/your/image.bmp /boot/kernel/splash.bmp
- or to change the default setting -
#
echo 'bitmap_name="/path/to/your/image.bmp"' >> /boot/loader.conf.local
Test by rebooting.
Using a ZSOFT PCX Image
Create /boot/loader.conf.local and add a line to it that will loader the vesa kernel module.  This can be done as root in one command:
#
echo 'vesa_load="YES"' >> /boot/loader.conf.local
Add a second line that will loader the bitmap kernel module.  This is needed even though a PCX image is being used.
#
echo 'bitmap_load="YES"' >> /boot/loader.conf.local
Add a third line that will configure the PCX image to be loaded at start up.
#
echo 'splash_pcx_load="YES"' >> /boot/loader.conf.local
By default /boot/kernel/splash.bmp is the image that will be loaded.  To use a PCX file the bitmap_name setting needs to be changed:
