New Revision: 25860
URL: http://svn.reactos.org/svn/reactos?rev=25860&view=rev
Log:
- Get rid of a bunch of multiboot crap FreeLDR was still doing for ReactOS.
- Remove some of the sixtuplicated routines to load a PE file. We're now down to a
single function which takes an ImageType parameter for DLL/EXE/SYS, but even this is still
temporary as the parameter will soon go away.
- We now load drivers in the same nice way that we load the kernel and DLLs, but we
don't yet process their imports and relocate them in FreeLDR, because FreeLDR
doesn't handle forwarders yet.
- We don't need a large hack in KiRosPrepareForSystemStartup anymore since the driver
base addresses are now proper.
- Don't free boot-drivers anymore, since we'll load them in place soon.
- Don't load bootvid twice.
- Remove PAE stuff in FreeLDR since we don't support PAE anyway in the kernel and when
we do, might as well implement it cleanly instead of relying on the broken FreeLDR stuff.
