Problem installing LAN driver on FreeNAS

Question

open source

GIVEN:
Realtek 8111f
FreeNAS 8.0.4 on USB

When the system boots, it does not see the network card.
I mount the FS: mount_msdosfs /dev/da1 /mnt
When copying the driver (cp /mnt/if_rl.ko /boot/kernel) I get a message: Read-only file system

Loading the same system on an old laptop does not cause problems.
