    Not always. We went through this dance once before on both the 4.X and
    5.X series. The last time we visited this question we had never seen
    BIOSes that couldn't deal with emulation booting. So we decided to
    stick with emulation booting with 4.X and, starting with 5.X, use
    non-emulation booting because it allows us to use the generic kernel
    when booting from CD-ROM.

    I'm pretty sure we have support for both types of bootable CD-ROMs in
    the bootstraps and the release building code on both 4.X and 5.X. Anyone
    who builds their own releases ought to be able to generate either type.
    It's not a goal of the FreeBSD Project to actually do this, but a vendor
    could do this as a value-add if they were so inclined.

    Bruce.
