I've tried the "modern BIOS" geometry and the "255 head" geometry.
I've ensured that the first slice (boot slice) is smaller than 1.5

is, but it doesn't seem to want to tell me. At least, I can't find
it in the BIOS menu anywhere. When I boot from the CD-ROM with
the 255 head geometry, though, it complains about the disk geometry,
saying 16h,63s != 255h,63s or something like that - it flies by
pretty fast (is there a way to go back and see that from the CD-ROM
"boot only" boot?).
I'm using the "Standard" boot manager, and the entire disk is devoted
to FreeBSD.

Suggestions, please? I'm making zero headway right now. :(
What version of FreeBSD are you running????
Well, yes, I suppose that would be a good bit of information!
What I'm *TRYING* to run is 8.0. It seems to install successfully
(of course - after doing all that), but then when I try to boot
from the hard drive, I see an otherwise-blank screen that says:
Invalid partition table
and that's as far as it goes!

There are reports of this sort of thing caused by 8.0 fdisk when doing a
install from scratch over a hard drive that all ready has an older
version of Freebsd installed on it.
The solution is to force the scratching of the MBR on the disk first
before running sysinstall fdisk.
Boot a LiveFS CD, then at a root prompt do:
sysctl kern.geom.debugflags=16 and:
dd if=/dev/zero of=/dev/adx oseek=1 bs=512 count=1
where x equals your drive number.
OK. I did exactly that. I confirmed that the second 512 bytes were zero
by doing a dd if/dev/ad0 bs=512 count=2 | od -c
and everything from 001000 through 002000 was zero.
But I still got "Invalid partition table" after the installation.
I guess I should set up one of my other systems as a local mirror.
I've done the installation so many time already, and it looks like
I'm not done yet!
On the 8.0 fdisk/MBR subject.
Doing dd if=/dev/zero of=/dev/adx oseek=1 bs=512 count=1 was the
solution from another post to the list with subject 'SunFire X2100
fails'. Here is another post that gives more details
http://www.freebsd.org/cgi/getmsg.cgi?fetch=322687+326879+/usr/local/
www/db/text/2009/freebsd-questions/20091227.freebsd-questions
It seems in 8.0 gpart was introduced and a change was made to fdisk to
support its sector o mbr format. 8.0 fdisk and disklabel are now broken.
Searching the list archives may shed more light on your problem.
Hmmm. This seems to describe a case where fdisk fails to change
the slice table. That is definitely not my case. The changes
certainly get made. The next time I go to retry the installation,
it has the information I gave it the previous time. I suppose it is
possible that it is putting it (and reading it) in the wrong location,
which is why the MBR throws up.
The problem is that I have a finite (and smallish) amount of time
in which to solve this. It seems like the most expedient route
forward at this point may be to try to install 7.2 and see how
that goes.
OK - well, I just tried with 7.2. I got exactly the same results.
After what seems like a successful installation, I try to boot from
the hard disk and get "Invalid partition table." Should I try Boot
Manager? Could that make a difference? Is it possible that this
combination of BIOS, processor, disk drive, etc., just isn't going
to to do for me? I can't just keep throwing hours at this problem.
Something is wrong with the MBR. Do
dd if=/dev/zero of=/dev/ad0 count=1 to blank out the MBR
THEN
Do you have a bootable win98 cd or floppy that contains the msdos fdisk
pgm. If so boot that and fdisk the hard drive. If not do you have a XP
install cd? Boot that and select fdisk and format. After format
completes the xp install will auto reboot. Pull the xp cd, power off and
try the 7.2 install again. If you have another desktop running xp. Open
the box and cable that hard drive to the motherboard, power up and use
windows explorer to select that hard drive. you will get prompt that
drive is unformated. answer yes to format.
Bottom line is use some other system to fdisk that hard drive before
trying 7.2 again.
One last thing to ask. Before you tried to install 8.0 on that hard
drive was it running some other operating system. Can the hard drive be
dead and you not know it??
