hi all!!

i have one question whose convincing answer i couldn' find in any
book.
everybody knows that dos has 640kb barrier..and hence this makes dos
inefficient...
my question is if dos is such a weak operating system..then why
somebody like microsoft(creater of ms dos)didn't redesigned dos so
that there could be no 640 kb memory limit...why they chose to develop
memory managers like himem and extended memory manager etc....
why microsft waited for winnt to eradicate dos...??? why ms didn't do
it before...
hope i am clear in conveying my question...

regds,
yogesh
