ok- have got one stage further. The laptop was built for 98SE but I did a clean install of 2000pro.

I downloaded the 98SE driver from Toshiba and got it to pick up the system file.

In Device Manager under Multimedia Audio Controller, there is an exclamation mark. I reinstall driver, get Windows Update to search for a suitable driver.

It says it has found one more suitable than mine. I can either get one from c:\winnit\inf\oem3.inf or install another suitable driver (Crystal Sound Fusion CS4281 WDM Audio).

Then it goes on about the digital signature not found etc.

Problem is it asks me for the W2000 installation disk in order to copy files. What should I copy from the W2000 disk? The filepath defaults to D:\i386, but that's no good and my process stops there....
