Do you intend to put more than one OS on the disk?
You need to have at least one of the DOS partitions bootable. This is
because of the BIOS limitations. Note the comment in the output of
fdisk. This machine has a BIOS limitation of 504 MB.
On an old IDE system, with a 2062 MB disk, DOS partition 1 is 400 MB
and bootable, DOS partition 2 is 99 MB and bootable, DOS partition 3
is 399 MB and not bootable, DOS partition 4 is 1163 MB and not
bootable.
DOS Partition 1 is WINNT 3.51 OS
DOS Partition 2 is FreeBSD 2.2.6 OS (/ and /var)
DOS Partition 3 is WINNT 3.51 Data
DOS Partition 4 is FreeBSD 2.2.6 /usr
Study the outputs of fdisk, disklabel and df carefully.

# fdisk
******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=4191 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=4191 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector nuMegering starts with sector 1
