I've received several private emails with suggested solutions. The
simplest one for me (since I do have FreeBSD up and running on the
system was to use the boot0cfg command thusly:

    boot0cfg -B -s 4 -m 0xd ad4

Now, to my original problem (that caused me to overwrite the FreeBSD
boot manager with another that I tried called GAG).

This particular system has a single 300 GB harddrive installed with four
Slices (partitions in the DOS vernacular) setup as follows:

1   Windows XP (~100 GB)
2   Linux swap (~2 GB)
3   Linux root (~82 GB)
4   FreeBSD (~102 GB)

With the FreeBSD boot manager (and with GAG) I can successfully boot
Windows and FreeBSD, but not Linux. It's as though the boot record is
not being found (geometry problems?).

Perhaps someone out there has a suggestion on what's wrong, and what
can be done to fix it. 

Thanks again,
Bob
