I've got two motherboards recently. They run well. The bios can detect FPU's existing, but I have no software to test the performance of WEITEK's FPU. Is there anybody who can tell me where to find the software?

If you are prepared to test the float operation performance difference between 3167 and 4167, you can write a simple program by yourself.
but be sure make them running on the same frequency.
the simple program may resemble the following codelet:
double x=0;
for (long i=0; i<10000000; i++)
for (long j=0; j<10000000; j++)
x+=(1.0/j);
when finished, record the time elapsed.
well, this is to calculate how fast it may be for float multipication and division.

It needs the dummy rapid cad in the FPU socket? (SZ625) |

3167 and 387 are not pin compatible
3167 has 121 pin
387 (rapidcad-2) is 68 pin
according to this site
www.cpu-collection.de/?l0=co&l1=Weitek&l2=386%20FPU
it is possible to have a system with 386+387+weitek 3167
but how does it look like? |
