Those tools aren't dependent on the architecture you're running, so debian should have them. You can download the netwide assembler here: http://nasm.sourceforge.net/ > I have gcc which I understand can also assemble assembly programs. could > someone please guide me how to use gcc to write and build assembly programs > that can be written into boot sector so that I can boot with it. See, in Linux source code, arch/i386/boot/*.S. They use directives instructing gcc to generate 16-bit code. Also, check the sources of syslinux: http://syslinux.zytor.com/ It's a Linux (and other things) booter, so it already does what you want (and more, much more). Oh, and yes, this definitely isn't the forum to ask. This is about kernel development (for newbies), not about development under Linux.
