I have looked into it a bit more, and found this:

Once again, it is Linux-centric, however, it does provide a more portable solution. This here is my attempt at a FreeBSD variant of the Linux solution linked to above:
Code:
# get and extract FreeDOS image
fetch http://www.fdos.org/bootdisks/autoge/FDOEM.144.gz
gunzip FDOEM.144.gz
# Create memory disk and mount. mdX is a place holder,
# mdconfig will indicate the proper device.
mdconfig -a -t vnode -f FDOEM.144
mount -t msdosfs /dev/mdX /mnt/floppy
# Copy bios update app to disk and unmount. Replace
# update.exe with the name of the executable from Dell.
cp update.exe /mnt/floppy
umount /mnt/floppy
# Make ISO and burn to CD
mkisofs -o boocd.iso -b FDOEM.144 FDOEM.144
cdrecord -v bootcd.iso
Please note: this has not been tested, use with caution.
Once the system is booted with the CD, you should get a DOS prompt of some sort. Enter the name of the Dell executable to run it.
