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
