uefi boot?

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

In the old days, on i386/amd64, one used to run disklabel, installboot
and fdisk to make a disk bootable. What is the method in post-disklabel
3T disk days?

Should

# gpt show wd0
       start        size  index  contents
           0           1         PMBR
           1           1         Pri GPT header
           2          32         Pri GPT table
          34          30         Unused

# gpt biosboot -i 1 wd0
/dev/rwd0d: Partition 1 marked as bootable

be enough? (with /usr/mdec/boot in /)

I updated the BIOS just in case, and get "Missing OS".

I suppose I'm asking "What does gptmbr.bin do?" (vs bootxx_ffsv2 etc)


Cheers,
