How to get HDT to work?

[VirtualNobody]

What is the trick to get HDT working?

I'm using undionly to try and boot/run the HDT tool. I downloaded HDT 0.5.2 from the HDT project website.

I'm doing a chain to http://server/hdt-0.5.2 I 've tried .img .img.bz, and .iso, all of which result in a format error. I tried http://server/hdt-0.5.2.c32 which just says OK, then hard hangs.

I see people seem to be booting hdt into pxelinux first, but the menu example from the ipxe examples shows booting the .img file via sanboot.

So I'm kinda confused as to how this is supposed to work.

Thanks for any help...
