It is certainly true that you do not need to have MORE THAN 1MB.
In order to get Windoze 3.10 with 1MB to work, I had to configure it so
that 384K (or even just 64K) was seen as having address above 1M. The
botom 640K does not need to be fully populated - one of my 3.10 ATs had
512K starting at address 0h, and another 512K (surely could have used 64K)
starting at address 10000h
HIMEM.SYS, and consequently Windoze 3.10 require a working A20 line, and
at least SOME memory accessed with a 1 in A20.
