From the shell prompt, I run sysinstall with no
arguments both from mfs and from a CDROM. As far as I can tell,
the screens are identical in that there is nothing new to turn
on or off when I run sysinstall from mfs. It immediately selects
ad0 as the drive to format:

I type y to okay the geometry.

The following commands are supported (in upper or lower case):
A = Use Entire Disk G = set Drive Geometry C = Create Slice
D = Delete Slice Z = Toggle Size Units S = Set Bootable | = Expert m.
T = Change Type U = Undo All Changes W = Write Changes
Use F1 or ? to get more help, arrow keys to select.
I type the a and then the q to use the whole disk.
I enter the parameters on the next screen and here is
what it looks like when filled in:
FreeBSD Disklabel Editor
Disk: ad0 Partition name: ad0s1 Free: 0 blocks (0MB)
Part Mount Size Newfs Part Mount Size Newfs
---- ----- ---- ----- ---- ----- ---- -----
ad0s1b swap 1024MB SWAP
ad0s1a / 37122MB UFS2 Y
I then installed the 8.0installation CDROM which calls
sysinstall after one enters country and terminal settings and
went through precisely the same steps except that I chose the
CDROM as the FreeBSD installation source as the network is not
up at that point.
The screen for the bsdlabel editor under the CDROM is identical
to that under mfs except for one line which may be due to the
manner in which I captured the screen shot. None of the values
are different. Here it is for the record:
FreeBSD Disklabel Editor
Disk: ad0 Partition name: ad0s1 Free: 0 blocks (0MB)
Part Mount Size Newfs Part Mount Size Newfs
---- ----- ---- ----- ---- ----- ---- -----
ad0s1b swap 1024MB SWAP
ad0s1a / 37122MB UFS2 Y
The following commands are valid here (upper or lower case):
C = Create D = Delete M = Mount pt.
N = Newfs Opts Q = Finish S = Toggle SoftUpdates Z = Custom Newfs
T = Toggle Newfs U = Undo A = Auto Defaults R = Delete+Merge
Use F1 or ? to get more help, arrow keys to select.
After filling in the bsdlabel screen's parameters and
selecting distributions, that is when we get:

Whatever it is that differs between using mfs to run sysinstall
and the CDROM to also run sysinstall is not obvious, at least to
me.
Sorry for the length of this message and I hope all the
little boxes and box parts didn't wreck anybody's terminal.
