Batch2OS

A Batch to native 16-bit x86 compiler, made in Rust.

Usage

Batch2OS <input> <output> <baseAddress> <loadAddress>

Example

Batch2OS os.bat kernel.bin 0x7C00 0x1000

Try it out!

After you've compiled your batch script as a bootable image file, you may want to try it on bare metal now. If that isn't possible, you can try it out in a VM. Here's an example with QEMU:

qemu-system-i386 kernel.bin

Compatibility

Batch2OS emits x86 code that is theoretically compatible starting from the Intel 8086. That is because Batch2OS currently uses real mode BIOS interrupts, which are 16-bit and were introduced back in the 8086.

Supported commands

• help
• cls
• echo
• pause
• ver
• color
• goto

Limitations

• Uses BIOS interrupts to do pretty much everything
• It's limited to loading up to 255 sectors because of the byte limit

TODO

• Go into protected mode (and figure out how to replace the BIOS interrupts with equivalent code??)
