Graphics on a bootloader

Question

Managed to create a simple bootloader... and with VESA 2.0 I managed to change the resolution to 1024x768x32, also managed to setup a Linear Frame Buffer... Where can I find tutorials for using the frame buffer? Like lets say to display a picture before it finishes to load?

So far I saw one sample on how to "draw" an ipod...called CdPod

Answer 1

If you have the address of the linear framebuffer all you need to do is to copy the raw image data to it's location.

Answer 2

I'm sorry I never tried to code a bootloader however maybe you can find your way looking at the source code of XOSL.

Answer 3

Check out the syslinux project on syslinux.zytor.com - you should find some code for it in that project

Answer 4

It's for x86 architecture?
If true, then look for old DOS tutorials for working with video memory.
May be something like that: "Farpointers and video in DJGPP"

Really, all new is well forgotten old :-)

Answer 5

Grub? It's open source, you may check how it works.
