Thats right the latest ver of DexOS ver 6, is released.

New ver has much improved FAT support.
New GUI API's.
New and updated Apps.
Full TCP/IP stack updated .
Cleaned up code.
And a new layout, to make the whole OS fully module.

All source to OS and Apps included.

Now work starts on a full USB stack for DexOS.

Just download the DexOS.zip from web site:
http://www.dex-os.com/

This is a video of old ver (5) run on one of the worlds smallest, x86 PC :

Great work Dex4u!!! Unfortunately when I run DexOS on my computer, I could not see background image of OS, because instruction GUI was not working. But on video it looks perfectly.

By the way, I think that DexOS is actually the answer to my question in my post http://board.flatassembler.net/topic.php?t=14261. That`s why I want to ask questions. What file and library from source code are responsible for the output image on the display(as I understand it`s jpeg image)? I want to write simple boot loader with the image, but I am a beginner and I do not have any suitable examples Sad .

Thanks pabloreda and long live r4 Wink

@Rusik, Its seems your vesa does not support 800x600 24/32 mode.
You could try the very old ver of DexOS that users 640x480 24/32 mode.
See here: http://www.dex-os.com/old/index.htm

Anyway to your problem, DexOS can load jpegs, gifs, bmp's or Dif's.
DIF stands for (DexOS Image Format), Dif is the same as a jpeg, but with a
alpha channel, it does this by including a normal jpeg and a alpha ver of the jpeg in one file using Fasm.
examplw
Code:
;=========================================================;
; Dex Image Format  (DIF)                        02-04-09 ;
; Also can be used for (DFF)                              ;
;---------------------------------------------------------;
;                                                         ;
; (c) Craig Bamford                                       ;
;=========================================================;
use32

               org    0x0

               db     'DIF1'                  ; 4 byte id
               dd     Image1                  ; Normal image
               dd     Image2                  ; Alpha image + Normal Image size
               dd     Image2Size-Image2       ; Alpha image size
               dd     Image2Size              ; info

Image1:
file   'ScrMenu.jpg'                          ; NORMAL Jpeg
Image2:
file   'ScrMenuAA.jpg'                        ; ALPHA Jpeg
Image2Size:                                      
    


So thats the file formats supported by dex-os, but to try to help you, try to run this app (vesaDemo.zip) run from DexOS CLI to see if that works .
(Just add it to the DexOS disk)
If not let me know what vesa modes your PC supports (you will find test programs on the net) and i will send you a example.

If you go to: http://www.dex-os.com/

and download dexos.zip the jpeg stuff in located in the folder:

C:\DexOS\DexOS_v6\Gui_DexOS_2012\DexOSDash\Jpeg

The DexOS GUI requires a video card that supports VESA 2, 800 x 600 screen, 32 bit color, and a linear frame buffer. That's the hard part about newer pc video hardware, the only standard you can totaly count on is that they have a windows driver and they have a text mode so the system bios works. Other then that most support most of VESA 2. Most doesn't help if your card or the mode you want isn't part of what is supported

Dex4u problem is that I do not know how add it to the DexOS disk. In folder \DexOS_v6\Gui_DexOS_2012\DexOSDash I find file Gui.asm where was the inclusion of jpeg images and I tried to write something like this
Code:
Format Binary

       mov  ax,cs               
       mov  ss,ax

       mov  ah,13h
       xor  al,al
       mov  cx,V8086ModeLength

compile it and put *.bin file to boot sector of my USB flash, but of course it did not work. I get message only Loader started. Disk read error. Is it possible to do similar to the following principles?

Yes DexOS was one of the first OS's after Dos to run in JS emulator, many yeas ago, it was set up by a DexOS team member, but its down now.

That's never going to work, it uses alot of stuff thats in kernel32.exe.

Did you try the app for DexOS i posted above ?.

Or try and replace kernel32.exe from the DexOS disk with this kernel32.exe which is a simple boot a bmp image demo.

Thanks Dex. But is it possible to rewrite BmpView.asm from format MZ to format bin or img and change 8-bit bmp to 24-bit?

Yes, but does your vesa mode support 24bits ?.

Also mz format can be tested in Dos or it can be loaded using bootprog or by replacing the kernel32.exe in any DexOS boot disk (must be called kernel32.exe).

See here for bootprog http://wiki.osdev.org/BootProg

As I know VESA standard is not specified a mandatory back-up byte code point. Therefore, the video card, for which he is absent, and the code points in just 24 bits, which formally correspond to the requirements of the standard VBE 1.2. As I said I tested the example by Madis731 http://board.flatassembler.net/topic.php?t=11609, there is used a small background bmp 24-bits per pixel and it works correctly. But this bmp multiplied on full screen and I want one big image on full screen. I tried to change the image, but because it was unable to compile the code (perhaps because the file size went beyond 1.44 Mb).

By the way Dex as I understand your background image in the DexOS increased to fit the screen and it prevents the withdrawal of one image pixel on the display. For example the background image is one pixel red. During the withdrawal of this pixel is displayed by a group of pixels of red color. Right?

This is a demo of DexOS's TCP/IP stack in action, running DexOS web server on local lan

Also DexOS running space invaders, ide etc.

I have to agree, you have done a great job cleaning up the source, integrating all the old functionality and just made it much more modular and complete. Smile

I think DexOS and BOS where a head of there times, because if you take a look at the so called modern OS's like whats on the I-Pod, I-Pad or the coming win8, not only are they moving to a more single tasking, one app full screen, but also the GUI is more like a game console menu, like DexOS was in 2004 Wink .

The best part was, i was going to call DexOS the 'Game Pod' in 2002, but my girl friend said the Pod part did not sound right, the rest is history Crying or Very sad
