Hello,
I have several different Dell PowerEdge servers running various branches of
FReeBSD ranging from 4.4 (nameserver only), to 6.0.
I have had excellent success compiling kernels and am quite comfortable with
the process.
I was wondering what strategy people use to 'KNOW' which drivers a
Thanks all for the info

Yes.

No.
CPUTYPE will add compiler directives to CFLAGS and COPTFLAGS (the
kernel version of CFLAGS) telling gcc to produce CPU-optimized code.

I believe the CPUTYPE will affect the kernel, but you shoul

I haven't yet found notes on optimizing the kernel by
telling the compiler I have a Pentium rather than just
a 386-compatible processor. I presume these lines
in the kernel configuration file deal with this:
machine i386
cpu I386_CPU
cpu I486_CPU
cpu I5
