Kernel Project

This is a kernel project that uses a multiboot header to boot, instead of a custom bootloader

Compiling

To build the kernel.bin, i686-elf-gcc and the i686-elf binutils are required. To build the ISO, grub, mtools, and xorriso are required. The Makefile can be found in the compile/ directory.

To build the full ISO, run make

To build just the binary file, run make kernel.bin

To autolaunch the kernel in an emulator after build:

• With QEMU: make qemu
• With bochs: make bochs

  • Kernel Data
  • User Code
  • User Data
  • Null Segment
• Setup IDT structure
  • Handlers for reserved interrupts
  • Handlers for 16 IRQs
• Configure PIC
  • Ability to set/clear IRQs
  • Remapped IRQs to IDT entries 32-47
• Configure PIT
  • Interval can be set in terms of milliseconds
