101 PrivateBootInfo has fields used by the booter that used to be part of
102 KernelBootArgs_t *bootArgs. When the switch was made to EFI the structure
103 completely changed to boot_args *bootArgs. This (new to boot-132) structure
104 contains the fields the kernel no longer cares about but the booter still
105 uses internally. Some fields (e.g. the video information) remain interesting
106 to the kernel and are thus located in bootArgs although with different field names.
