Using UMBPCI the way you did is not a good idea if Jemm386 is to be installed as well. Since UMBPCI is loaded after Himem, it will install itself as an "UMB provider", which might be a problem if Jemm386 also has to supply UMBs (FreeDOS accepts ONE UMB provider only). Better is:

DEVICE=D:\DOS\UMBPCI.SYS /I=D800-EFFF
DEVICE=C:\WINDOWS\HIMEM.SYS /TESTMEM:OFF /Q
DEVICE=D:\DOS\JEMM386.EXE X=D000-D3FF S=D800-EFFF
