- In NTLDR boot, try to get the first kernel physical address from the loader entries.

- Fixup HAL's image base in the loader parameter block, since we load it at a different place then freeldr tells us.
- We've reached a dead end in NTLDR compatibility. Out memory manager initialization code makes some assumptions which are totally incompatible with the page table state that NTLDR gives us.
