I suppose you are kind of right here.
I have a machine with 80MB installed
The WIN95 dos bos reports 66,112 K(an odd number) total memory when mem 
command is issued so I lost 14 MB
WinNT detects the 80MB but I don't remember how much report the mem 
command. I will ckeck that and the outputs of go32-v2 in plain DOS 7.0 and 
in WinNT dos box and post the results when I have some time.

Thats my 2 cents.

Fernando
