I'm running Win '98 on two machines that I use for personal business purposes. I have a network of only two machines, so my needs are fairly simple. Both of my machines have greater than 256MB of RAM, but Win '98 can't recognize that add'l memory. Friends have said that I should upgrade to Win 2K and others have said to upgrade to Win XP. I would like to get creative opinions from you experts for a solution that (ideally) will not involve cleaning off my hard drive. Again, my main objectives are to minimize the upgrade hassle/work and tap into the memory that I have > 256MB. Suggestions/Comments?
