- Implemented basic FDC capable of reading floppy disc sectors - Now PIT timer can be used, as it counts the ticks - Now the keyboard is buffered, instead of being accessed only during the interrupt itself - HAL for sleep() - gets() - atoi() - Now shell is not called by the IRQ, but it's a procedure that reads the key buffer
