ApolOS

ApolOS is an operating system built from the ground up to explore the fundamentals of x86 architecture. It orchestrates a precise transition from 16-bit Real Mode to 32-bit Protected Mode, manually mapping the Global Descriptor Table (GDT) and establishing a custom execution environment at memory address 0x1000.

Developed in a hybrid of Assembly and C, the kernel manages low-level hardware interfaces, including direct VGA buffer manipulation and an Interrupt Descriptor Table (IDT) for real-time input handling. The system features a dedicated command-line interface designed for monitoring deep-space NASA missions and real-time CMOS telemetry.
