Sorry, but I had to respond to this. It's all plain wrong.
FreeBSD need not be in the first partition. However, there are reasons
it has to start within the first 1024 cylinders. For example, here is
the output from 'fdisk' on my system (note the FreeBSD fdisk not
DOS's),
# fdisk
******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=787 heads=128 sectors/track=63 (8064 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=787 heads=128 sectors/track=63 (8064 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6,(Primary 'big' DOS (> 32MB))
start 8064, size 4193280 (2047 Meg), flag 0
beg: cyl 1/ sector 1/ head 0;
end: cyl 520/ sector 63/ head 127
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 4201344, size 2145024 (1047 Meg), flag 80 (active)
beg: cyl 521/ sector 1/ head 0;
end: cyl 786/ sector 63/ head 127
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
As you can see my 'DOS' (Win95) partition is first.
Philip also made it sound like you should install Win9[58] /after/
FreeBSD. Do NOT do this. Win9[58] will clobber your bootstrapper
without asking.
Now, my suggestion for Laurence,

Try booting with your boot floppy. When you get to the boot.help
screen, tell it to boot from where ever you installed FreeBSD. As the
help shows, if you are booting from the second 'slice' (which is what
DOS calls a partition) of an IDE drive enter,
1:wd(2,a)
If it doesn't work, I'm not sure what to tell you other than perhaps
send your fdisk output and disklabel info to the list.
HTH.
