How to boot kernel.old version in 5.4

[fbsd_user]

In 5.4 after compiling a new kernel you have the default boot location being
/boot/kernel/ directory containing the current newly compiled kernel and
/boot/kernel.old/ directory containing the generic system.

For safeguard I do
mkdir /boot/kernel.generic
cp -Rfv /boot/kernel.old/ /boot/kernel.generic/


Now my question,
At the beastie boot menu I select option 6 for boot prompt,
What do I enter to load from /boot/kernel.generic/ directory??
