Author DOS emulation in 64-bit Vista
Peter B. Steiger

2007-08-02, 9:55 pm

Well, the moment we feared has begun: We got our first call from a
customer suckered into buying a 64-bit PC with Vista, and sure enough
there is no 16-bit emulation support at all.

I tried DOSBox (an open-source DOS emulator with Windows and Linux
builds) but it doesn't deal real well with DPMI apps. Are there any
other (preferably inexpensive) third-party solutions that would allow a
Clipper program to run in protected mode under Vista 64?

I pointed out that he could use dosemu if he wipes out Vista and installs
Linux instead, but I always get in trouble when I recommend replacing
Winduhs with Linux.

(x)Harbour, depending on your 3rd party libs.

1. You can use VMware Workstation to build virtual machine (virtual appliance).
The customer can use free VMware player:
http://www.vmware.com/products/player/

3. Virtual PC 2007 is also free:
http://www.microsoft.com/windows/pr...pc/default.mspx

There are two more virtualization products, buth IMHO they do not support Vista x64:
A. innotek VirtualBox
http://www.virtualbox.org/wiki/Guest_OSes
http://searchservervirtualization.t...1263623,00.html
B. Parallels Workstation
http://www.parallels.com/en/products/workstation/
http://forum.parallels.com/


BTW, regarding DOSbox and DPMI, maybe HDPMI can help - I don't know:

Peter:

Whatever you make with it actually, are asprins trying to cure a cancer,
none 64 bits operating system will run 16 bits applications, not even if
they were windows GUI applications.

Time to move 32 bits pal, go the xHarbour way, it will "eat" all your
Clipper code, if you are using 3rd parties, well, you may need to look
for 32 bits version of them or if you have the source at hand you can
recompile them with xHarbour.
