Thank you... very true, but the sites are very little helpful, i.e. looking like a lot of drivers are not listed, even though they are less than 2 years old, which I find strange. OK, I'll get back over the next few days to ask for advice on those that prove elusive.
And no worries with regard to network access, I have a second computer fro which I can hunt and download until the network adapters are working.
On a quite different matter - how do I proceed with e.g. a chip-set driver for Win7 that is only available as a self-extractive exe-file (that installs the driver without any questions). What I need is probably the drivers unpacked on a flash-drive, but is there a good way to get them out of the exe-file without installing them - which I do not want at this point.
