I am trying to set up GPT booting. With netbsd-6 I took a 3T USB disk made a 1G gpt partition newfs'd it and unpacked sets ran "gpt biosbioot -i 1 sd0' ran installboot to /dev/rdk0 with bootxx_ffsv2 copied /usr/mdec/boot to dk0 I would expect then that BIOS will load sector 0, which has gptmbr gptmbr finds index 1 and loads 2nd-stage loader bootxx_ffsv2 loads /boot /boot can load kernel But trying to boot this disk on an old mac doesn't work. So, I am wondering if my take on gpt booting (that on netbsd-6 and up it works) right? Can anyone share positive/negative experiences? Is /boot not booted from gpt expected to be able to load kernels from gpt partitions via "dev hd2a" or seomthing? Is there some /boot command to list devices?
