I thought you'd said without DOS, but here's what confused me:

Quote:

Exit: ; Exit code
Mov AX,3h
Int 10h
Mov AX,0x4C00
Int 21h

Also, FYI, if you're writing 16-bit, 8086-compatible code, check out MCD's ONLY8086.INC include.

P.S. You can "push ax bx cx dx" all on one line (but, unlike Octasm, you'll have to pop in reverse: "pop dx cx bx ax"). Also, don't forget that local labels exist: "good_hor[12] and good_ver[12]" -> "good: .hor1: .hor2: .ver1: .ver2:".

(Not that it matters, but you may prefer a cleaner approach).

This block code is for my tests when I working in FreeDos. (for not have restart and boot the mouse program all time)

I had a look at your code (did not anlyze the port accesses in detail,
use my hints with care) and tested it. The no-OS version ends up
in a hard freezer in text screen mode. Sad

Quote:

This block code is for my tests when I working in FreeDos. (for not have restart and boot the mouse program all time)

Quote:

but here's what confused me:
Code:
Mov AX,3h
Int 10h
Mov AX,0x4C00
Int 21h
    

It's perfectly possible and useful to test no-OS code in FreeDOS Smile

Also INT $21,$4C00 is no problem ... you just have to explain it better Shocked

Code:

Jmp   InstallMouse  ; Load the mouse

MainCode:              ; Use the mouse loaded
   Mov   AX,12h
   Int   10h

You probably should swap them:

1. Set video mode
2. Activate mouse

Code:

Mov   CX,CX
Mov   DX,DX

What does this code do ? Laughing

Code:

 mov   ax,0x2574
 mov   dx,mouse_code 
 int   21h

This is the problem. This must be kicked in the no-OS version, as you
found out Smile

and commented it out with no replacement Confused

Maybe an
unhandled IRQ occurs Confused

Code:

cli

Why do you ban interrupts ? Where do you re-allow them ? Seems to be
part of the problem as well Confused

Quote:

Mov AH,0Ch
Mov CX,CX
Mov DX,DX
Mov AL,15
Int 10h

Xor AX,AX
Mov AH,11h
Int 16h

This probably also contributes to the problem. After hacking on IRQ's
and ports you maybe should no longer use BIOS INT's either Confused

Hi all

I correct the mouse driver...
source1 (DOS)

Code:

   mov   ax,0x2574 
   mov   dx,mouse_code 
   int   21h

NTOSKRNL_VXE

Thanks for your help, your helps is correct!

I have changed it for create one "Interrupt vector" without DOS, I only changed it... now... mouse runs correct in pure code!!! Wink

Thanks for all help...

There has been alot of people with mouse problem in the forum, so i have code a simple demo, of a working mouse driver, that does not use any OS code and is fully self contained.
Here is the fasm code and a bootable program to test it, (Note: it will run from dos, but not a dosbox under windows).
http://www.dex4u.com/tuts/MouseDemo.zip

I will add comment in the next day or two, but for now, the code is there.

PS: The demo is running in MiniDos, if you want the code let me know.

Hi Dex4u

Good idea... it help very developers... my mouse already runs correct... I use "Set Interrupt Vector" of "MiniDos" (I already the source)... Wink

... this is very util... my code is very small... I think... thanks for you initiative and good work.
