It's nice of you to write.  The conversation is pleasant.  Here's how  
I found an answer:

Google

     etherboot .zhd

Check out the 2nd link:

     http://sourceforge.net/mailarchive/forum.php? 
forum_id=6402&max_rows=25&style=nested&viewmonth=200508

See that that relevant message there (the one with .zhd in it) quotes  
a message from the previous month:

     http://sourceforge.net/mailarchive/message.php?msg_id=12512726

This method erases a partition, and would thus not be suitable for  
all situations.  If you have a hard drive, and you have (or are  
willing to put) a filesystem on it, you may want to consider .zlilo  
files, and a kernel bootloader, such as grub or lilo.  For example:

Note that there are other ways to load Etherboot from a hard disk.   
One such way is to use a .zlilo file, and have grub or lilo load it.

Such as:

     http://www.wizzy.org.za/article/articlestatic/14/1/2/

or

     ftp://ftp.scyld.com/private/jlehan/pxe-on-a-disk.html

Let us know how things go.
