LOL this is a classic admin exam question
It should run automatically from when you insert the CD (if you have autorun enabled)
otherwise its EITHER
From within windows<b/>
(where X=your CD/DVD Drive letter)
x:\setup.exe (this is what autorun should do)
this gives you the front end installer
or x:\i386\winnt32.exe (from windows explorer)
this opens the "blue screen" installer
From a commandline<b/>
you should be able to boot directly from the XO CD
(press any key to boot from CD.....)
or finally
boot from the win98 startup disc (with CD support).
access
x:\i386\winnt.exe
this runs the 16 bit blue screen installer
follow the prompts
lol 5/5
having said all that
you can't beat a clean install ....
far far better than upgrading
make sure before you start (in every case) that you have all the drivers for mobo, graphics, sound etc
