I'm not sure what you mean by this.

I mean hardware, and I believe I am using the correct sinit, as I use 
the same sinit that allows tboot to work on each machine in question. My 
code works on an HP dc7800 with Q35_SINIT_16.BIN, and it works on a 
Lenovo T400 with GM45_PM45_SINIT_19.BIN.

Yes, tboot works perfectly on the HP 8530p.

I can and will if I must but I am mostly just seeking to understand a 
little more about what the "SINIT Exit Point" error means.  Is this 
related to the "return entry" you mention above?

Thanks,
