    you get it, I thought /usr/src/sys/i386/conf/NOTES contained all valid
    options?

    You might be able to remove those options, if I remember right it
    explains in the freebsd handbook why you don't (and do) need these options.

    Arn't you dealing with a pci only board and chipset, why do you need isa
    support?

    Also setting make options will make things leaner and meaner too.
    something like (this is just an example, don't build anything with this
    set of options and expect it to work):
    CPUTYPE=i585/mmx
    MAKEOPTS="-j2"
    CFLAGS= -march=pentium-mmx -Os -pipe -s -fomit-frame-pointer -ffast-math
    COPTFLAGS= -march=pentium-mmx -Os -pipe -s -fomit-frame-pointer -ffast-math

    read this paper for a starting point on this stuff:

    Have fun with your new toy :-), I'd love to have one of these but can't
    justify the cost.
