The FreeBSD bootblocks do understand LBA, if the BIOS understands it.

The FreeBSD kernel doesn't understand LBA, but has no problems to
speak to ST-506-interfaced drives up to

j@uriah 683% echo '(2^16*16*255*512)/2^30' | bc
127

gigabytes, or at least

j@uriah 684% echo '(2^16*16*63*512)/2^30' | bc
31

gigabytes if the drive is also to be used by the BIOS.

Obviously, only the first 1024 ficticuous cylinders of such a drive
will be addressable by the BIOS.

Never trust an operating system you don't have sources for. ;-)
