TomAwezome 1d4d8dc86e Fix limine uefi missing SYS_FONT_PTR by hardcoding a new aux font dedicated file. 
Since Zeal used a 16-bit mode BIOS INT to get an 8x8 VGA ROM font, this is incompatible if Zeal is loaded to a patched 32-bit mode by the zealbooter prekernel. To circumvent SYS_FONT_PTR never being set and fix access to the 'thick' font with Ctrl-Alt-F, I loaded Zeal bare-metal on my Thinkpad T420 and saved the VGA ROM font file with FontEd, then transferred the file to my VM.

ZealOS

Discord

The Zeal Operating System is a modernized, professional fork of the 64-bit Temple Operating System. Guiding principles of development include transparency, full user control, and adherence to public-domain/open-source implementations.

ZealOS strives to be simple, documented, and require as little of a knowledge gap as possible. One person should be able to comprehend the entire system in at least a semi-detailed way within a few days of study. Simplify, don't complicate; make accessible, don't obfuscate.

The CIA encourages code obfuscation. They make it more complicated than necessary.
—Terry A. Davis

Features in development include:

Changes include:

  • 60 FPS
  • VBE graphics with variable resolutions
  • Reformatted code for readability
  • Added comments and documentation
  • HolyC -> ZealC
  • System-wide renaming for clarity

Getting started

Prerequisites

  • For running in a VM: Intel VT-x/AMD-V acceleration enabled in your BIOS settings. (Required to virtualize any 64-bit operating system properly.)
  • Working knowledge of the C programming language.

To create a Distro ISO, run the build-iso script. Check the Wiki guide for details on building an ISO. After creating an ISO, see the Wiki guides on installing in VirtualBox, VMWare, and bare-metal.

Contributing

There are two ways to contribute. The first way involves everything happening inside the OS, as intended by Terry. After you've built the latest ISO, installed to a VM, made your changes, and powered off the VM, you can run the sync script to merge your changes to the repo.

Alternatively, you can edit repo files using an external editor, outside of the OS.

Afterwards, you can make a pull request on the master branch.

Background

In around November of 2019, VoidNV forked ZenithOS from TempleOS. Releases of pre-git ZenithOS are currently archived on the mega.nz website. The repository was removed in August of 2020, and reuploaded to ZenithOS. The latest archived front page, master.zip, and related links can be found on archive.org.

In July of 2021, ZealOS was forked from ZenithOS.
