These Kernels are for Warp4 FP15, CP, WSEB, etc.

UNI is for ACP/MCP Single processor.
SMP is for ACP/MCP Multi processor.
W4 is for Warp 4 FP13+.

There are a few differences, as follows:
- W4 will work properly with 486sx chips. UNI will not (reliably).
- Uni and SMP kernels enable a codepage object of some sort in the shell. I forget the details
- W4 did not until recently support loading a PSD

You only want to load an SMP kernel if you really have two or more physical
CPUs. Not because it won't work -- all three should work on any system where
any works (except for 486sx boxes) -- but with an SMP kernel you have a lot
of overhead not present with the UNI kernel. This may incur as much as a 20%
performance penalty!
