You can easily boot FreeBSD with LILO. Do not install the FreeBSD boot selector (Booteasy) if you want to use LILO. Append the following lines to your /etc/lilo.conf file and run lilo (assuming the FreeBSD slice is /dev/hda4):
other=/dev/hda4
table=/dev/hda
label=FreeBSD
If you have installed FreeBSD on the second SCSI drive, use something like this (the FreeBSD slice being /dev/sdb2):
other=/dev/sdb2
table=/dev/sdb
loader=/boot/chain.b
label=FreeBSD
