I triple-boot two of the above three (I have NT4 instead of FreeBSD.)
NT boot loader owns the first drive's boot sector, and it gives a
choice of NT & DR-DOS. Then, the two first lines of my DR-DOS
config.sys are these: (Ctrl-I/Tab characters excluded)
Timeout 5
? "Boot Linux instead?" chain = c:\linux.sys
and the linux.sys file is a single line:
shell=c:\loadlin\loadlin.exe c:\loadlin\zImage root=/dev/hda5 ro
Loadlin is flexible and easy, IME, and pretty fast, too. If I wanted
Linux as default (which I eventually will, on this machine) I'd use
? "Boot DOS instead?" chain = c:\dos.sys
as the second line of config.sys, and the linux.sys shell line would
follow. The DOS stuff would be moved into dos.sys, of course.
My Slackware is a converted ZipSlack installation, and that's how I
got started using Loadlin. I have two other machines using LILO, and
I think Loadlin is every bit as fast and as good as LILO. The only
reason I switched to LILO on them was because I needed to recover the
partitions used for FAT volumes.
There are countless ways to multi-boot. Insofar as multi-booting DOS
systems is concerned, I myself am partial to the menu scheme used by
MS-DOS 6+, but only because I've used it more. The DR-DOS way is just
as good. But going into DOS only works with Linux because of Loadlin;
I have no idea if FreeBSD has a similar DOS tool available.
IBM's boot loader is another good option. I've used the one which was
supplied with Partition Magic, and I'm sure it could do it. A limit I
discovered there was that DOS would only boot off of the first
partition of the first IDE drive. That also applies to Win9x systems,
AFAIK. But Linux & NT can be in other places. (I've read about a need
to keep below physical cylinder 1024 for Linux, but I am not sure how
or when that applies.)
Good luck,
