> mem /c still shows UPPER = 0 :(

I don't know the DRDOS "mem" program, so I can't help here.

type JEMMEX on the command line, it will show its current state; for me it displays:


emmEx v5.79 [09/09/18]
JemmEx v5.79 installed.
EMS is Off.
VCPI is On, 96 of max. 30816 pages allocated.
DMA buffer at 00120000, size 64 kB.
A20 emulation is On.
VME is Off.
PGE is Off.
UMB supplied at cf1f-e6ff, allocated.


the last line tells me that there is one UMB block, which has been allocated (hopefully by DOS)

If the last line reports UMBs that are "free", DOS won't use them.

MS-DOS forever!
