🔊 In this video I showed step by step the process to create a kernel which is the basis for an Operating System. The boot was performed on the physical machine and we were able to print directly to the VGA with a 32-bit system made with C++ and GNU Assembler.
To build on your machine
Use the package manager to install GCC, make, as and ld
sudo apt install build-essential
Clone the repository and compile:
Then just compile:
git clone https://github.com/terroo/terminalroot-os
cd terminal-root-os/
make
To test on QEMU, for example
sudo apt install qemu-kvm
And then test:
qemu-system-i386 -kernel terminal-root-os.bin
Even with
qemu-system-x86-64 -kernel terminal-root-os.bin.
If you have a virtual or physical machine with GRUB Legacy, you can move to /boot and edit grub.cfg:
Example:
sudo mv terminal-root-os.bin /boot/
sudo vim /boot/grub/grub.cfg
Add a new entry to GRUB:
### BEGIN TERMINALROOTOS
menuentry 'Terminal Root OS' {
multiboot /boot/terminal-root-os.bin
boot
}
### END TERMINALROOTOS
