Cls Magic X86 Official

While we now work in high-resolution GUI environments, the logic of "CLS" remains fundamental for several reasons:

To perform the magic, you simply need to decide between (BIOS interrupts) or raw performance (direct memory access). Both methods reflect the core philosophy of x86: giving the programmer total control over the hardware. cls magic x86
