So I'm benchmarking some math software on a 386 with FPU, and want to measure the performance impact of the FPU.
But I don't feel like physically removing the chip - anybody knows a program to disable it?
Sorry, but that's way beyond my pay grade.Write software that ises the CPU and FPU directly? Find some different software?
Since you're the OP I would suspect that's your responsibility.How about shifting that i key one to the left.
Have you tried a coprocessor emulator?Mathematica on startup displays a warning about the lack of FPU, but later on works as usual.
No, but I doubt it would do any change.Have you tried a coprocessor emulator?
I remember there was a DOS utility, hide87.com, for that purpose.So I'm benchmarking some math software on a 386 with FPU, and want to measure the performance impact of the FPU.

There was some problem with the forum, recent posts got lost, so let me reply again...I remember there was a DOS utility, hide87.com, for that purpose.
I believe it was from German c`t magazine. However, I have not really tested it.
