MosquitOS is a tiny x86_64 UEFI-based operating system built from scratch.
Goals:
- 64-bit kernel
- UEFI bootloader
- Pre-emptive multitasking
- Multiprocessor support
- PCI support
- USB support
- Basic filesystem
- Virtual memory
- Bootable on a real computer
Compilation:
Note: I do all development on Ubuntu 16.04. Other Linux environments should work just fine. I cannot get the code to compile on Mac OS X, and I have not tried Windows.
-
Make sure
binutilsandgccare installed. -
Install
gnu-efi. On Ubuntu this can be done with:
`sudo apt-get install gnu-efi`
-
Install
tupbuild manager. -
Run
tupfrom the base directory to start the compilation. -
This will produce an EFI bootloader file (
build/bootloader) and a kernel file (build/kernel) that can be used to boot a virtual machine.
Running in VirtualBox:
-
Install VirtualBox.
-
Create a new virtual machine with type 'Other' and version 'Other/Unknown (64-bit)'.
-
Highlight the new virtual machine. Go to Settings->System and check 'Enable EFI' under Extended Features.
-
Create a new FAT-16 formatted CD-image (on Mac OS X this can be done in Disk Utility) and copy
build/bootloaderthat you compiled earlier into a file called/EFI/BOOT/BOOTx64.EFIon the disk image. Additionally, copykernelinto the root directory of the disk image. -
Attach the disk image as a virtual CD to the VM with a SATA controller.
-
Add a virtual HD under the same SATA controller. You can delete the existing IDE controller.
-
Boot the VM, it should boot off of the CD image and into MosquitOS.
