Hello,Mark,Dim,David,Evan and all,
Thank you very much for your email regarding the
Triple-boot in one HD,i will try some of them and see
what will happen.
Before that,i downloaded opendos in my HD in which
already got win95 and winnt4.0,but as soon as finished
Od7.02 took over control of Boot sector and could not
get back to win95 or NT,then i reinstalled win95,and
it scandisked HD during the setup process,and could not
get through it ,HD was very noisy,it seemed spining difficult.
then i tried to copy some data file into my smaller HD
and could not copy successfully,so i took HD to computer
shop to swap a new one,they said different Fat system
in one HDD can kill the HD,is that right?
the new HDD 4.3g is still empty,i am more careful now,
i dont know how to put win95,NT,opendos7.02,
in OpendosFAQ,it says from win95 can boot to previous
dos(opendos),and i tried it ,it didn't work,as win95
search for msdos io files,not ibmbio,i have set bootmulti=1
but not work,so i install win95 first then opendos7.02
and dual-boot is successful,but still thinking of NT..
