- Inkbox demonstrates creating a computer game that runs directly on hardware without an OS.
- Explanation of BIOS and UEFI, including UEFI's origins from Intel and its open-source adoption by TianoCore.
- UEFI provides boot services (memory management, running applications) and runtime services (system clock, reset).
- x64 CPU boot process: jumps to 0xfffffff0, enters protected mode, loads firmware, and runs UEFI Boot Manager.
- Development system specs: AMD Ryzen AI 9 HX 370 CPU, 32GB DDR5 RAM.
- Assembly language program details: console I/O, system time/date, graphics output, and multi-core execution.
- Space Game for x86 runs via simple graphics programming and mouse input.
- Discussion on bare-metal programming: potential performance boosts vs. development costs.
- Debate on compiler efficiency vs. hand-optimized assembly for performance-critical code.
- Mention of unikernel microvms for security and visibility over code.
