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