PXE Boot Custom ISO / Image in DS 7.6

Hi,

We need to be able to deploy a bootable ISO via the NBS (PXE) server in DS 7.6, has anyone been able to do this?  It was a simple option in 6.9 where we had a menu of WinPE or various flavors of ESXi to install. 

In DS7.6 the ESXi deployment requires a working LinuxPE environment, but when using SSL across the board, this doesn't work and there is no schedule fix at this time.  I even have trouble getting drivers for my HP standard hardware and so the LinuxPE route seems to be a dead duck from the outset.

If anyone has some insight into getting a custom PXE menu option in DS7.6 please can you share?

Thanks.
