I haven't tested this yet, but AFAIK Jemm does NOT and never did detect UMBs provided by UMBPCI. It may display the warning: "system memory found at x-x, region might be in use". To include such regions into Jemm's UMB pool one has to use the S=xxxx option ( not recommended, because ram activated by UMBPCI may have restrictions [ DMA, access time ] ).

However, there was a (documented) change in v5.79: Jemm calls int 15h, ax=e820h to get "reserved" regions in C000-FFFF. If this call is supported, it relies upon the result, and does partly skip its own testing ( it still scans for ROMs ).
