+# UefiDiskAccess
+Simple Demo of Accessing Disks with Block I/O Protocol
+
+## Introduction
+This project is a simple demo of accessing disks using Block I/O Protocol in UEFI Environment.
+
+## Requirement
+To run this project, a working computer with UEFI firmware is required.
+
+## Build
+If it is your first time to build this project, you should run `build_prep.bat` to prepare for compilation. <br>
+The required compiler for this project is Win64 LLVM. You may download it from [GitHub](https://github.com/llvm/llvm-project/releases). <br>
+The required library for this project is TianoCore EDK II. You may download it from [GitHub](https://github.com/tianocore/edk2/releases). <br>
+You are required to pre-compile the EDK II library. The method to compile is unofficial. You may use the script from [EDK II Library](https://github.com/MickeyMeowMeowHouse/EDK-II-Library) to build EDK II library. For detailed steps to pre-compile, consult that repository to proceed.
+
+## Test
+Setup a USB flash stick with GUID Partition Table (GPT). Construct a partition and format it into FAT32 file system. <br>
+Copy the compiled `bootx64.efi` to `\EFI\BOOT\bootx64.efi` in your flash stick. <br>
+Enter your firmware settings. Set the device option prior to the operating system. Disable Secure Boot unless you can sign the executable.
