Vista won't support full screen fb Dos apps?

[thriller]

I tested some apps compiled with gfx and -target dos .17, they seem not working under windows vista.
Can it be solved?

dos <> windows

You don't expect a program to work on an OS it's not compiled for, do you? Why would you want to do that anyway?

[cha0s]

Please, relieve modern OS's of the burden of DOS! *starts anti-DOS demonstration*

/me burns a DOS.

...okay I'm done. No idea about the actual problem.

It's probably along the lines of the DPMI limitation under Vista. Basically Microsoft is trying to tell you to drop the dead donkey.

The problem is actually the new WDDM video driver interface used in Vista, which doesn't support int 10h. Apparently if you use XP video drivers DOS graphics work ok, but you won't have Aero.

I remember when a member of the QB Forum tried QBasic on a beta version of Vista, and QB didn't go full-screen there, either. Either the display methods don't work with DOS emulation, or the DOS emulator has been redone to prevent full-screen. Either way, FB is not the problem. :-)

Yeah, most DOS apps haven't worked for me since Windows XP, and I don't know why I would want DOS to work on XP anyways. Hey guys, Mac + DOS on Windows + Linux ftw!

YES. Select the target correctly: DOS for DOS, Windows for Windows.

This in NOT a FB's fault ;-)

Or do you run applications compiled for Linux-x64 on Windows 3.11 ?

[KristopherWindsor]

My QB Programs worked in XP because I didn't use the low-level tricks. :D

[Mindless]

You could always run it in DOSBox...

[Veggiet]

hmm. I probably has something to do with the graphics drivers. for example, I can play lots of DOS games full-screen on my pc running XP, but on my dad's xp computer the dos program starts but the moment it tries to switch to fullscreen it exits to the desktop, the only differences I can think of are that his is the Media Edition, with Nvidia graphics card and LCD monitor, mine has an on-board graphics, no special-edition, and crt monitior, which is really a shame because I think he played a lot more dos games than I do, although I do enjoy them every now and then, Commander keen etc...

If you really need to run DOS programs, get yourself a 486/Pentium I/II. Those machines are in the €0 to €10 price range nowadays.

haha, thanks for your advice.

But I really meant if we test our dos progs under vista, they may just not work.

And even qemu also does not work.

Ok, that's not problem of FB at all. I just wanted to ask how can we solve it.

thanks.

It seems that the development on Qemu stalled somehow. But VirtualBox uses Qemu code and is GPL. I use it regulary on Linux (PCLinuxOS 2007) and Windows 2000 and it rocks. I ran FB compiled DOS programs in VirtualBox emulated FBDOS.
My two cents.

Maybe you have an old version of QEMU? I remember the windows ports being a little slow to happen. I've used it sucessfully to run DOS, Windows, and Linux as virtual machines, that was using 0.7.x on windows IIRC, and on linux it all worked even better and faster, as I used the kernel module.
