### Build and Run
#### Compilation
From the project root:
```bash
cd src
nasm -f bin boot.asm -o ..\build\bios.bin
```
This produces a raw BIOS ROM image (bios.bin) suitable for direct execution by QEMU.
#### Execution
The QEMU VGA BIOS must be copied into a local rom/ directory.
Default locations of `vgabios.bin`:
Windows
`C:\Program Files\qemu\share\vgabios.bin`
Linux
`/usr/share/qemu/vgabios.bin`
You can use an video bios from the 86box's project:
https://github.com/86Box/roms
Copy it to: `roms/vgabios.bin`
Then run QEMU with:
```bash
qemu-system-i386 \
-bios build/bios.bin \
-device loader,file=roms/vgabios.bin,addr=0xC0000,force-raw=on \
-device isa-debugcon,chardev=myconsole \
-chardev stdio,id=myconsole \
-k be \
-display sdl
```
This command:
- Loads the custom BIOS as the system ROM
- Injects the VGA BIOS at 0xC0000
- Redirects debug output to the console
- Displays graphics using SDL
