You're making Microsoft partitions (which we call slices), not UNIX
partitions (which is what Eric was demonstrating above). You can have
a maximum of four slices (Microsoft partitions). Each slice can
contain 8 (UNIX) partitions. You should use one slice and put all
your partitions in it.

This isn't a SCSI issue, it's an administrative issue, so I'm moving
it to -questions.
To do this right,
1. Use one slice only. In the partition editor, create one FreeBSD
slice (Microsoft partition).
2. Go to the disk label editor and create 3 (UNIX) partitions: root
file system (/), swap and /usr. Don't create any other file
systems on the same disk unless you know *exactly* how big they
need to be. Otherwise you're going to run out of space in one
partition and have space left over in others. In your case, you'd
expect to have:
Part Mount Size Newfs
---- ----- ---- -----
da0s1a / 996MB UFS Y
da0s1b swap 251MB SWAP
da0s1e /usr 7400MB UFS Y
3. After installation, create a directory /usr/var and make /var a
symbolic link to it. You don't need an /opt file system, but if
you want one, do the same thing with it. Do I detect an SNI
background?
