Prototype Bootloader

This is the first parametrable bootloader of Prototype-OS.

Warning: The kernel is expected to be concatenated to the bootloader, this bootloader works only for floppy disk images.

A parametrable interface has been written, which allows you to know the machine configuration (memory for example).

You can write your kernel with:

• x86
• C

You must configure the file prototype-bootloader.conf to renseign the size of your kernel.

Requirements:

Ubuntu

sudo apt-get install libc6-dev-i386 to enable you to cross-compile to i386

PB Compilation

• configure prototype-bootloader.conf
• cd build && make

Your Kernel Compilation

If the kernel is written in x86: use [ORG 0x1000]

If the kernel is written in C: use gcc -m32 -c -o kernel.o kernel.c and ld --oformat binary -m elf_i386 -Ttext 1000 kernel.o $(YOUR_ASM_OBJ) $(YOUR_C_OBJ) -o kernel

Creating a bootable kernel (for floppy)

cat bin/bootsect your_kernel /dev/zero | dd of=floppyA bs=512 count=2880

And use "floppyA".

How to test

cd bin/examples/x86/ && qemu kernel1
