I have just install the 32-bit 5384 build and the network card was not installed. Should this card have been auto installed - if not then where can I find the driver for it? Thanks

Try to fire up Device Manager, locate the offending device, delete it and do a hardware rescan. If the drivers are (still) supported, Vista should automatically install it. As 3Com 3c905cx is a fairly old NIC, it may be possible that it is no longer supported in Vista. HTH.
