I am unsure of what I can do with boot blocks. 000000000011111111112222222222333333333344444444445555555555666666666677 Here is what I've done so far. I have just created my first GPT structured FreeBSD system and it's all working fine, but I don't have any ability to select booting from another partition or drive. I boot the system and FreeBSD just boots with no option to boot from another disk. I have /boot/pmbr loaded into the PMBR and gptboot into the freebsd-boot partition. I'll admit that I did this by rote and don't understand how these two files interact with the UEFI BIOS to get the loader started. I'm not really certain that I even need both. Is it possible to build a "custom" booteasy boot system with boot0cfg or some other tool so I can select d ifferent bootable partition or my other disk which is sliced in the traditional fashion? Can anyone point me to any information on how the boot process works with GPT? Thanks! -- R. Kevin Oberman, Network Engineer - Retired E-mail: kob6558@gmail.com
