- fdboot is the 512 byte which will be loaded to address 0x7c00 on boot-up.

- fdboot then executes to load the subsequent sectors 2-13 which is where

- fdboot and bootfd are both binary, no header at all,

- as represents adaptec 1542 scsi, wd represents winchester drive.

- Note that floppy5 has no pa entry, which means that partition a corresponding
- to /dev/fd0a is missing. You can only use /dev/fd0b or /dev/fd0c
-
- You can play with partition info here.
- Create pd which must represent the entire drive. In fact pd is the default
- partition for disklabel without any partition name.
