|Neither of those system will come close to being able to run Windows 7. And why so much RAM on the 98 machine & so little on the XP machine? 256MB RAM isn't enough to run XP decently.|
The 98 machine *probably* has 384MB with 64MB going toward the onboard video. If both use the same type of RAM, I would lower the amount of memory to the onboard video to 32MB, then yank one stick of RAM (128MB?) & put it in the XP machine.
And what exactly is wrong with the XP machine anyway, you didn't say?
