Hi 👋! I am Rieidi.

Low-level enthusiast focused on computer architecture, firmware and hardware diagnostics.
I work close to the hardware — from Assembly to board-level repair.

⚙️ Core Skills

• x86/x86_64 Assembly (real mode, BIOS, bootloaders)
• C / C++ for low-level systems
• Python for tooling and automation

🔧 Hardware & Low-Level

• BIOS recovery and SPI flash reprogramming
• Board-level laptop diagnostics (power rails analysis and troubleshooting)
• LVDS/eDP display troubleshooting (panel, cable, common faults)
• Notebook hardware repair and component replacement

🚧 Current Work

x86 Bootloader (in progress)
- Studying BIOS interrupts and real mode
- Implementing disk read routines (INT 13h)
- Exploring multi-stage boot process

🧠 Currently Learning

• x86/x86_64 Assembly (real mode, bios and low-level systems)
• Computer Architecture & CPU internals (pipelines, registers, memory hierarchy)
• Microarchitecture fundamentals
• Compilers and code generation
• Operating Systems internals
