Not sure what i should think of it. Here is an
good example (DRDOS 7.x in an SVISTA virtual machine):


  Memory Type           Total Bytes ( Kbytes  )       Available For Programs   
                                                                               
  Conventional              655.360 (    640K )          619.984 (    605K )   
  Upper                     163.840 (    160K )           95.136 (     93K )   
  High                       65.520 (     64K )           10.797 (     11K )   
  Extended               32.505.856 ( 31.744K )                0 (      0K )   
  Extended via XMS             --------               31.391.744 ( 30.656K )   
                                                                               
  Largest executable program:  619.968 ( 605K )                                
  Total Free DOS memory:       715.120 ( 698K )                                
                                                                               

The interesting line is "Upper" in yours and "High" in
mine. I assume
that both mean the area of memory that is 1MiB..1MiB+64KiB-1.

Even when DOS allocates the HMA completely, it should say 64K and not zero 
for size. My recommendations

a) try another himem.sys (Windows/FreeDos/QEMM/..)

b) use the not attached (ask) A20OO.COM, but
   'INSTALL=C:\PATH\A20OO.COM' in first config.sys line

And if your BIOS has an option to enable shadowing, i would
enable all areas.
