hello
Having installed successfully 386BSD running Xwindow in 1024x768
on a 486/25 or/33 with XL wonder, the next step for us was performances.
As our private benchmark tests did not satisfies us, the question is :

a) Does 386BSD use the internal Floating Point Processor(FPP) of the 486?

b) Does libm.a emulate the FPP operation to be portable on 386 w/o 387?

c) Is there some tools to check if the FPP is being used?

d) using gdb> info float<cr> does return me NOTHING! Is is suppose to
  to tell me something?

e) Should I get my hand on a special library?
