virtualbox.org

I have a program that was written for win3.1/NT, I have run it on 98 and 2000 hosts before. I have a win 7-64bit host, Vbox 4.3.10 r 93012. the native Video card is a Nvidia k600.
The program does floating point math, and I assume it's trying to pass the calculation and a pointer to the GPU. In win98SE, win 200, and win XP-32 guests I am not able to successfully run the program.
In XP it throws an win87em.dll error, in the other guests it locks up at the same point XP throws the error, so I imagine there is a common triggering event, my assumption is it trying to push the flop to the GPU and it not seeing one.

I tried putting Sci-tech display on the 98SE guest and that didn't not resolve the issue. didn't think it would, but was worth a try.

I can provide more info if needed, just let me know what would help. Thanks in advance.

If the program is written for Windows 3.1 then it does not require a GPU. Perhaps you meant an FPU (Floating Point Unit). This became integrated into the main CPU a couple of decades ago. Do try to keep up...

So in answer to your question: yes, VMs can do floating point no problem.
