Tis the season for upgrades to my son's computer- 400Mhz K6-3 to ECS MB with 735 chip set and XP 1600+. He however threw me loop and installed Windows XP. If I understand XP registration system correctly, it registers lan cards and bios changes and probably won't boot after upgrade. He's home for two days and I'll need to get it up and running while here. Does anyone know what the proceedure is or will a bended knee to all mighty MS be required. PS Lean, Clean Win 98 forever!!
