I used to have the same problem except that it was Lotus 1-2-3 Rel. 3 that
couldn't run because of 0 K extended memory.  I assume you must be using
DOS at least DOS 4.0 and the SMARTDRV.SYS that comes with Windows 3.0.
What I did was to use the SMARTDRV.SYS that comes with DOS.  If you do that
DOS' mem command will report the correct extended memory size, at leas on
my machine it did.  However, after running Windows, the extended memory
size my return to 0 K but I could still run Lotus 1-2-3 even though DOS'
mem command reported 0 K.  DOS' SMARTDRV.SYS doesn't support two parameters
like Windows' SMARTDRV.SYS so you have to set a maximum but not a minimum
for SMARTDRV.  I benchmarked my system using Windows' SMARTDRV and DOS'
SMARTDRV and DOS' SMARTDRV was slightly slower but is worth switching to
if you want to use other extended memory programs besides Windows.
