I have put the NetBSD boot program in at
ftp://beta.datastorm.com/pub/NetBSD/DOSbootblock/

Get either the tar.gz or zip file, all programs in all caps are the
contents of the archives, so you can safely avoid them if you get one of   
    

the archives.

Send me E-mail of your successes and failures.

Neat trick, copy the kernel, netbsd, to your root directory of your DOS   
    

partition and just run boot.com with no parameters. NetBSD will start to   
    

load off your DOS drive.  However, once the kernel gets past the device   
    

detection, it will drop into the debugger.  Not very usable, just
an interesting exercise.
