32 bit singletasking C kernel
SanderOSUSB
Thank you for showing interest in SanderOSUSB! SanderOSUSB is a 32bit single tasking monolythic kernel that is supposed to run from USB or cd-rom.
Compiling
For compiling you need the following programs:
- gcc
- nasm or fasm
- xorriso (grub)
sudo apt install gcc nasm xorriso
And then run the file /kernel/build.sh [ARGS] to generate kernel file
Where:
- empty : only generates a kernel.bin file
- --grub : generates a grub-iso image
- --pxe : generates a pxe image
Runing the OS
- install qemu
sudo apt install qemu qemu-utils qemu-kvm
- go to the repo directory
- run:
qemu-system-x86_64 -cdrom ./cdrom.iso

- Marble
the following bootmethods are supported:
- GRUB2
- PXE
- qemu --kernel loader
Directories
- boot: Grub bin folder
- kernel: Kernel source code
- lib: kernel static library to which programs attach to
- programs: example programs
Instalation on CDROM
- build system with
./build.sh --grub - burn cdrom.iso to a cdrom
Instalation on USB
- make a usbstick with EXT as filesystem
- run
sudo grub-install --target=i386-pc --root-directory=[mountpoint_filesystem] /dev/sdb - copy grub command file
sudo cp ../boot/grub/grub.cfg [mountpoint_filesystem]/boot/grub/grub.cfg - copy kernel
sudo cp ../kernel.bin /media/sander/SOS/kernel.bin
