yes ibm os2/warp came 1st before win-nt os2 was working with dos befor ms was around. ms was working with drdos may be never heard of him
but bill bought doc dos copy rights then went and sold it to Ibm
and that was history now dos is very were did you know that windows base systems are still using 386 kernals LOL even then the new XP and server 2003 what a joke LOL unix is far beter and faster the ms by far just think of ms like the old saying were do you want to goto day ?
insted were don;t you want to goto day or
in a hanycap wheel cahir were do you want to goto day
point is that unix just works
i was a very big MS fan die hardcore but got very tired of there bs
so i'm a switcher to unix and never been happier mate once you switch you will not want to go back to MS
