# Nanite
A Very small OS that can run on X86 Hardware.

Good luck figuring out the spagetti code i write... (sorry not sorry ;D)

Designed for older computers such as a Pentium (i586) Class Machine.
I however would recomend atleast a Pentium 2 Class System or higher.

## Features
- Support for the GNU GRUB 2 Bootloader and Multiboot V2
- Custom Theme for GRUB (Not Complete Yet!)
- Basic Memory Management
- Support for Floppy Disk Drives (FDDs)
- Basic Serial (RS-232) Support
- Keyboard Input

### Serial:
Runs at 9600 baud (as its fairly standard)
Serial is mostly used as a debug output (In the future this will be able to be enabled/disabled)

#### Note: Kernel is currently under very heavy development. All things are subject to change at any time.

## Building
Run `./build.i686` inside main directory of repo, however you may first need to run `make toolchain TARGET=i686-elf` (you can also build for `xtensa-esp32-elf`) i would DEFINITELY use more than one job (building GCC takes forever)

To write to a disk, use `./write.sh` just enter a disk in at the prompt and it will build & flash nanite to it (ex. `/dev/sdb`)
You could also run `make all` but the scripts a bit better tbh, it even automates starting QEMU and building an image.

Theres also a way to debug it with BOCHS if need be, just run `./debug.sh` instead of the normal build script.

### Build Requirements
- make
- gcc (or really any C compiler)
- nasm

#### Only Required to Build the Image
- grub2
- parted

## How is Testing Done
Testing is mostly done with QEMU at this point as its easier, but I do sometimes pull out my Dell Latitude D610 to test on real hardware (for anyone wondering its completely maxed out. [2GB of ram Pentium M @ 2.23GHz])
I Also do some testing on a Dell Dimension 8110 (its at my desk 24/7 and has its serial port hooked to my desktop, lol)
