I wasn't able to get the plpbt.bin/img/rom files booted from the boot2 bootloader and or the kernel loader stage3 from FreeBSD8. Both of the loaders see the files on the local filesystem but will say the format is incorrect as I specify them for boot.
With grub or syslinux I can boot plpbt the sameway I boot memtest86.
Anyone experience howto let the BSD loader load something else other than a kernel or module?
