OEM will let you do a clean install. You will have to re-install everything. This is the preferred method.
If you want to upgrade, with all intact, you need the upgrade CD. You can do a clean install from the upgrade disk as well, but you will need to keep the original Win98 CD to do it.
I am thinking of upgrading to XP from Windows 98se.I notice on Ebay that there are some available (new) at reasonable prices.They are OEM.Or would I have to purchase an upgrade?I have 5.54mb of free disk.600 mg AMD.128 mb Memory. Could I install these on my PC?
