DOSBox is a DOS emulator especially made for playing old DOS games:

16 bit applications?

32-bit Vista runs 16 bit applications using the NTVDM ("NT Virtual DOS
Manchine") and, for 16-bit Windows apps, the WoW (Windows-on-Windows)
thunking layer.

Because of changes in the display model, Vista running with WDDM drivers
canot display character-mode applications full-screen. If (and only if) an
application requires full screen access to run, it cannot run on Vista; or
it must be run in an emulator like DosBox, as Synapse Syndrome correctly
suggests. Vista using a non-WDDM display driver can also display DOS apps
full screen (although this is not a recommended solution for the OP).

DOS applications can run just fine in a Window; likewise 16 Windows apps.
For example, I always run a copy of VisiCalc.com (c.1981) on every new
version of Windows, to test backwards compatibility. It runs fine on Vista.

64-bit Vista cannot run any 16 bit applications. This is an architectural
limitation of the CPU, and is also true for 64 bit XP and Server 2003.

Any DOS or Win3.x application is subject to all the usual compatibility
constraints when running on NT (eg cannot directly write to hardware
adresses etc). But apart from that, Vista has the same 16 bit compatiblity
as XP, Windows 2000 and NT 4.0 (in fact somewhat better, because there have
been numerous bug fixes to the NTVDM since NT 4.0).

Your statement is either wrong, or else you omitted important caveats
("Vista doesn't do 16-bit stuff. At all. on 64 bit Vista. But 32 bit Vista
is fine"; etc).

clue from:

"This symptom only applies to 32-bit versions of Windows Vista. 16-bit
programs are not supported on 64-bit versions of Windows Vista."

Hi Andrew You sound as if you know a little about this stuff
I have an origional Myst game (windows'95 I think) Will this be ok to play
on my new laptop which supports vista home premium, will I need to change any
settings? I'm a bit nervous of installing something that may disrupt
everything

Hi Penny
Heh, don't be fooled :-)
I'm pretty sure you'd be able to install Myst, without messing up anything
else. To be absolutely sure, create restore point, before you install Myst:

- go to Start menu
- select Control Panel
- select "System and Maintenance"
- select item "System"
- click on "System Protection" in left margin
- enter administrator credentials if propmted
- the "System Properties"panel will appear, with "System Protection" already
selected
- press the "Create" button, to cretae a system restore point.
- give it a name like "Before Myst" or similar
- press the Create button
- system will chugg away for a few moments, creating the restore point.

With a restore point safely created, you'll be able to easily roll back your
system, in the unlikely event that installing Myst does cause any disruption
to your system.

To roll back:
- go to Start menu
- in "Start Search" filed", type "system restore"
- select the "System Restore" program item
- teh System Restore Wizard will start. Just follow the bouncing ball,
selecting your restore point "Before Myst" to undo all the changes.

But hopefully, Myst will just install, and uninstall, normally.

As to whether Myst will actually *run* on Vista ... um sorry, I dunno. I
don't play computer games, so I have no first-hand expereince. You may need
to check out some of the Myst user forums to see what people's experience
has been.

Quicktime. (Which is bad). If you have a newer version of Quicktime
than the one that came with Myst (Quicktime v2 or v3?) then you may
have problems. For those games that don't like never versions of
Quicktime I usually just run them in Vmware/VPC/Qemu.

Also the DOS 16 bit subsystem is not supported in Vista. Best you play them
in VM with Windows 95 installed. Just download the free Virtual PC 2007 and
install Windows 95 and your favorite DOS games.

Hi Andre

This is a common misapprehension - but with respect, it is wrong. This kind
of misleading information should not be put out to the public.

The 16-bit Subsystem, in the form of NTVDM (NT Virtual DOS Machine) and
16-bit WoW (Windows on Windows) are present by default in 32-bit Vista, and
are fully supported by Microsoft. In general terms, 16-bit applications run
fine on 32-bit Vista. There may be specific compatibility issues, for
particular applications.

16-bit applications cannot run on 64-bit Vista. This is true, and is exactly
the same situation with existed for 64-bit XP, and 64-bit Server 2003.
NTVDM.EXE uses V86 instructions which are not compatible with the CPU's
64-bit mode.

I do agree, that Virtual PC is a good workaround for any applications
(16-bit or otherwise) which experience compatibility problems on Vista.

What is your basis for saying the DOS 16-bit subsystem is not supported in
Vista?
