JNos is a Graphical User Interface (GUI) for DOS. I thought I would try and write a GUI for DOS, as other GUIs didn't offer the features I wanted, also, it would probably be the closest I would get to writing an actual operating system for the mean time. These are the features it currently has:

Mouse Support
Run programs without using QB's shell command
Integrated Command Interpreter (CMDCONS), controls most aspects of the shell
Ability to bypass the GUI and use CMDCONS in text mode (if you don't have a mouse/VGA card)
Support for JNos compliant applications (spec coming soon)
StatusWin - see live status updates (GUI only)

Here are some pictures of it running on my Toshiba Libretto 110CT:

CMDCONS shelling out to a JNos Compliant Application (sorry about the yellowness of the picture)

JNos is written in QuickBasic and runs under DOS (MS-DOS, PC-DOS, etc), it runs quite fast despite the fact that QuickBasic is a slow language, although the the BMP loader is very slow (going to be sorted). JNos V1.0-2007 is heavily under construction and development is painfully slow (it was meant to be released last year, so V1.0-2007 will be changed to V1.0-2008).

Thanks to Lee Vidal at www.leev.co.nr for creating the Splash Screen

Limitations

Single Tasking - until I find out how to make a multitasking script interpreter without writing tonnes and tonnes of code, it will stay like this.
Slow BMP viewer - needs fixing up
Messy sources - I need to clean up the source code to make it faster and more efficient.
VGA can only display up to 16 colours - Will sort this out when I incorporate SVGA routines.

Next Version

Hopefully in the next version (if ever), I will hope to include this features:

TCP/IP networking
Built in sound
SVGA

UPDATE: V1.0-2007 Scrapped. Version2 being planned/designed now. I'm really do not have any spare time at the moment, especially with GCSEs approaching, so I probably won't be starting this until late July. However, here is the Version2 splash screen:

Design/Development sheets for Version2 can be downloaded here in .PUB (Microsoft Publisher 2003 format):

Batch File System
Compliant Apps
Boot Options
VGA Splash

Download

You can download a development binary below. Please note, it has many bugs, and not many features.
