Reserved memory areas may change, etc etc. Don't expect a very stable experience using this.\n\n## Boot sequence\n- For each unmanaged drives\n    - Load the first 512 bytes\n    - Check for boot signature(0xAA55 LE)\n        - If signature is valid, reset stack pointer and jump to the boot sector\n- Display error message and halt\n\n## Disk images\nDisk image created by some utilities, such as `mkfs.fat`, always have a boot sector signature. If you don't want the BIOS to boot a disk image, you can simply remove the said signature before compressing them for OpenComputers.\n\n## Building\n---\n\nBefore building this project, make sure you have the [LLVM-MOS SDK](https://github.com/llvm-mos/llvm-mos-sdk/releases) installed for compiling 6502 binaries.\n\n---\n\nRun the following commands from the cloned repository:\n\n```bash\nmkdir build \u0026\u0026 cd build\ncmake ..\nmake\n```\n\nYou should now have two built files, `bios.bin` and `bios.bin.elf`. The former is a raw binary file for flashing onto an EEPROM, and the latter contains the BIOS in ELF format.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fatirut-w%2Foceanbios","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fatirut-w%2Foceanbios","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fatirut-w%2Foceanbios/lists"}
