He's just saying you need to make room if you already have another OS
where you want to install FreeBSD. In your case, do you have a 150MB
partition on your first disk with Win98 installed there, or is the full
4GB disk devoted to Win98, of which 150MB are currently used? Sounds
like the latter, in which case you might want to shrink the Win
partition, though FreeBSD and all the apps you might want can almost
certainly live quite happily in 10GB. I haven't used parted. I have
used BootItNG, which has a free 30-day trial, and which I find to be
exceptionally easy to use and well documented. Despite the name, it
does resize and move Win partitions as well as function as a bootloader.
I have used it predominantly for the former, and to make compressed
images of my Win installation for backups. I prefer GAG for the
bootloader function. It's free, and, like BootItNG, is very easy to use.

Actually, you have ad0 4GB, ad1 4GB and ad2 6GB. "ad" is an IDE drive
in FreeBSD. "s" is "slice," close to synonymous with a Win "partition."
If my assumption is correct that the entire first drive is devoted to
Windows, then both ad0 (the drive) and ad0s1 (first and only slice on
the first drive) are around 4GB.

It would see ad0s1 (the first slice on drive ad0) as .5GB, ad0s2 as
3.5GB, ad1 as 4GB and ad2 as 6GB. If you do shrink your Win
installation, you might give it around 1GB, just in order to be quite
sure that you wouldn't have to play around with resizing partitions more
than once, but it's your call.
