So, did anyone get it to compile (to .SYS file?).

I think this does not require QEMM, correct? But it does require UMBPCI.SYS as listed in your sample CONFIG.SYS above.

What is purpose of this except to "fool" system into thinking QEMM is loaded? It still requires a seperate UMB and / or EMS driver as well as HIMEM.SYS to function, as I understand it. Sort of a passthrough or to shorten boot time?
