That "PCI board" is the type of weird error that some system devices show when you haven't loaded all the chipset drivers. With VIA it can be a crapshoot. As for what the last guy said, well, ME is a little slower and less stable than 98SE, but has more features. XP is a pig of an OS, if 98SE was your typical family sedan XP would be an army tank.
