I think ReactOS's registry is binary compatible with NT4. It and the windows 2000 format was
documented/reversed for samba and the linux ntchpwd bootdisk projects. If I remeber right Eirc
Kohl offered to release some of his work to Wine for the binary format so you might want to ping
him about the implementation details.

Thanks
Steven

There are 2 entry points, one for when you install freeldr in the bootsector
and one for when you call freeldr as a multiboot kernel from Grub. Both of
these entry points are in reactos/boot/freeldr/freeldr/arch/i386/arch.S (the
first entry point is at the top of the file, the second at MultibootEntry).
After doing some setup, both transfer control to BootMain() in
reactos/boot/freeldr/freeldr/freeldr.c. You should be able to pick up the
flow from there.

We have 2 sets of low-level routines for e.g. disk I/O. One set is for
normal PCs, the other for the Xbox. We're using a function table wrapped by
macros to call these routines. All these macros start with "Mach", e.g.
MachDiskReadLogicalSectors(). For a normal PC, this will translate to a call
to PcDiskReadLogicalSectors().
