The linker doesn't have that capability. However, the PE format is pretty
simple to write a converter for that will convert it to binary.

Hi, I have done this too. I made it up to be able to outpu text. But no  
input (yet). I'm using GRUB and than you can compile the stuff into ELF  
files via the Linux version of D. Makes things a lot simpler.

Using the MultiBoot standard (see
http://www.gnu.org/software/grub/manual/multiboot/multiboot.html), you won't
need a kernel image in a pure binary image, you can use non-relocatable
ELF/PE/etc...
GRUB (http://www.gnu.org/software/grub/) is a MultiBoot compliant boot loader.
To reduce the start-up time, you can use also OSLib
(http://oslib.sourceforge.net/overview.html), a library to ease the development
of operating systems. 
Freedos32 (http://freedos-32.sourceforge.net/) is an example of a MultiBoot
compliant OS that uses OSLib.

I don't know anything about this subject, but other people have taken steps to
write a small OS in D. Maybe some of the information on this page will prove
useful: http://www.prowiki.org/wiki4d/wiki.cgi?KernelWithD

Good luck!
