Hi
The drivers for Satellite C660 PSC1NE can be found on the Toshiba European driver page.
http://eu.computers.toshiba-europe.com
But I found just the Win 7 64bit drivers.. however it’s not the big problem to get Win 7 32bit drivers… you can use the Win 7 drivers released for the C660 PSC1GE series.
The Toshiba tools like Value Added Package, Flash Card Support Utility should function also on your model.
You should pay attention to some other drivers like display driver. The C660-2DZ supports the Intel® HD Intel® HD Graphics 3000 and Mobile Intel(R) HM65 Express Chipset… both drivers (or just the HM65) could be downloaded from Intel page.
Furthermore the notebook supports Realtek Wlan card and the driver can be found also here
