# HUSIS - Operating System for IBM PC and Compatibles
HUSIS is a text-based operating system for 8086/8088 CPUs, with custom EGA/VGA fonts to create an interactive and dynamic interface.
This Operating System will implement minimum DOS INT 0x21 function set to run [T3X/86 with Low Level Extensions](https://github.com/humbertocsjr/T3X86LL) and [T3X/86](https://t3x.org/t3x) Applications without modifications.
Recommended code editor: VS Code (with t3x extension added)
## Project files (*.PRJ)
This files contains filenames imported to unified T3X file used to build.
## EGA/VGA Fonts
HUSIS uses EGA/VGA 8x8 fonts, with 128 fixed chars (including CP850-like latin chars, upper case only), and 128 custom chars per application.
The app can read any custom font files into 128 avail chars, including UTF-8(pending) extensions and lower case versions(pending).
Font file format is 100% ascii file, optimize to easy user manipulation and edition.
## Current Roadmap Topics
- Full customizable font
- Library Manager
- User Interface Controls
- Window
- Label
- ListBox
- TextBox
- TextArea
- File Manager Implementation
- Test Multitask performance impact in User Interface API
## Changes in current release
- Shell Replacement
- User Interface prototype
- Font Manager
- Initial Bold Font
- Splash screen
[Download Floppy Images](https://github.com/humbertocsjr/HUSIS/releases/tag/v2022.11r0-alpha)
## Boot Order
- Bootloader - /BOOT/*
- Load HUSIS Kernel - /HUSIS/*
- Load Common Kernel Extensions - /SYSTEM/*
- Load Video Controller Kernel Extension - /SYSTEM/EGA.*
- Load Shell (User interface/Font Manager) - /SYSTEM/SHELL/*
- Load Application Manager (Event manager) - /SYSTEM/APPMAN/*
- Load File Manager (Main user application) - /SYSTEM/FILEMAN/*
## Terminal Implementation
This implements a static screen terminal without scroll function, my inspiration is IBM CICS from Mainframe, with forms based screens.
## Minimum Requiriments
IBM PC or Compatible
360 KiB Floppy Disk
EGA/VGA Video Card (MDA/CGA Video Card/Monitor is not suported)
256 KiB RAM (Standalone) or 384 KiB RAM (DOS App mode)
## How to use
You can run as Standalone Operating System or DOS Application.
The DOS Application mode preserves DOS Structures, and limit the RAM usage to area on MCB (DOS Memory Control Block).
#### DOS App mode
This mode is created for Debug use and running on machines with ROM DOS, need Minix File System in separated disk.
Run 'HUSIS.COM 0 80 2 18 /System/Autoexec.hsh'
Command arguments:
- Disk number: 0 = A:, 1 = B:, 128 = C:, 129 = D:
- Cilinders
- Heads
- Sectors
- Autoexec file path
## Build Requirements
- DOS(FreeDOS/MS-DOS/DOSBOX)
- MinixFS Tool
## Embedded Build Tools
- [T3X/86](https://github.com/humbertocsjr/T3X86LL)
- [Old-School Assembler](https://github.com/humbertocsjr/osasm)
- [MinixFS Tool](https://github.com/humbertocsjr/minixfs)
## Build on DOS
Use MAKE.BAT command to build
## Build on Linux / MacOS
Use 'make' command to build.
Use 'make img' to generate standalone floppy image
Use 'make test' to generate standalone floppy image and run on DOSBOX(Standalone Mode)
Use 'make testdos' run on DOSBOX(DOS Mode)
