How to restore FreeBSD boot manager on GPT disk ?

[Manish Jain]

Hi,

One thing I have loved about FreeBSD over the years is the superbly 
designed Boot Easy boot manager. If any other OS overwrites the MBR, it 
is straightforward to restore with 'boot0cfg -B /dev/ada0'

That command only works on MBR disks though, as far as I know. Is there 
any equivalent command on a GPT disk ?

Thanks for help
