OK, you asked!

BTW, after a certain amount of grief, I have non-ProxyDHCP PXE working. 
I can make a PXE Client put up a menu, and provide Boot service so that 
it can map from a menu entry to a filename.

It seems that PXE is a crawling horror. Badly designed, worse 
implemented, and worst of all documented. Rant over.

For ProxyDHCP, could you supply more information about the DHCPACK reply 
from proxyDHCP server. What port does it go to, what are the values in 
ciaddr, and yiaddr, is there a server identifier option? It's not 
obvious from the documentation, and I'm sick of answering such questions 
by experimentation and then have to throw away code because my 
assumptions were wrong :-(

Cheers,

Simon.
