How can I boot the second hard drive without proper BIOS or boot manager ?

[Olivier Smedts]

Hello list,

I was a happy user of boot0cfg and the boot0 boot manager until I converted
my MBR+UFS disks to GPT+ZFS. Now I use gptzfsboot but sometimes I'd like to
boot the second hard drive, and my crappy BIOS won't allow me to do that,
it only allows to boot from the first hard drive (sic...).

I'd like to avoid installing a full boot manager like grub2 (and I don't
know if the FreeBSD port supports ZFS). Is there anything I can do at the
"boot:" prompt to "chainload" the 2nd hard drive boot block ?
Or can I use the boot0 boot manager and boot0cfg to boot the "freebsd-boot"
GPT partition if it's mirrored in the protective MBR, like I used to do on my
old MBR layout ?

Thanks
