Booting FreeBSD-5.3 from NTLDR

[Rakhesh Sasidharan]

So that means I should install boot0 to the MBR of my second disk,
using boot0cfg with the "-o noupdate" flag, and then extract that MBR
(using "dd" for instance) to a file like c:\bootsectbsd? That should
work?

Or wait, maybe there's no need to extract. When I install boot0 to the
MBR, possibly the boot0 file modified also, and so I just need to copy
that to c:\bootsect.bsd and then boot using NTLDR. Right?
