OS Development - system memory reservation on startup

I am currently developing my own operating system kernel.

At the moment I am about to implement paging, and my problem is that I dont really understand what memory is reserved when the system starts, like the console video memory at 0x000b8000.

Where can I get information about what memory is reserved for the system and what I can use for my operating system?

Thank you! :)

Maybe this helps...

OTOH, how can you be so sure that the system has a graphic adapter. Those reserved memory regions should be reported/reserved/allocated by the device drivers (video, DMA, sata, usb).
