Hi, I've just tried to upgrade Win98SE to Win2000Pro on my old Compaq Deskpro 4000. It went through a compatibility list and gave the following: The following hardware may not support Windows 2000 without additional files. Hard disk controllers SMSC Hard Disk Adapter PDR (not currently present) Other devices VVRUSB Device (not currently present) Unsupported Hardware The following devices are not supported by Windows 2000. If you upgrade to Windows 2000, these devices will not work. Universal Serial Bus controllers VIA Tech 3038 PCI to USB Universal Host Controller Is this just MS covering themselves or will it really not work? I'm lost, this is too much for me. Any help on how I might proceed would be greatly welcomed. Thank you, R.
