On 08/29/10 08:09, Somebody in the thread at some point said:

I want to obtain an executable image from C files by gcc for 32 bit Intel CPU.
I do not want gcc add some headers and so on. I want a code with
absolute addresses so that I can write the code directly on a BIOS
chip and boot a computer from it.

Can gcc do that? Do i need any extra tool to do it?

It's not a gcc issue, look into ld scripts.

Here's an ld script I use to place sections from a gcc link of a bootloader:
