- Overview An overview on most of the topics covered by
- Hello World The kernel says its first words…

- The GDT One of the architetcture specific chapters, the Global Descriptor Table, used to “describe” the behaviour of different part of memory

- APIC The Advanced Programmable Interrupt Controller, along with the IOAPIC they replace the old PIC to handle interrupts coming from external hardware
- Timers We initialize, configure and start a timer
- PS2 Keyboard Overview Introduction to the PS2 Keyboard Driver implementation
- PS2 Keybord Interrupt Handling How to handle the interrupt generated by the keyboard, and introduction of some of the basic concepts
- PS2 Keyboard Driver implementation Finally how to translate the scancode we received into readable characters.
