The order of installation matters. I would install these before other drivers.

Use this driver for the LAN.

The equivalent European part-number family (PSLY5E) has plenty of other Toshiba drivers and utilities for Windows XP. They are here.

I suggest installing the hotkey utility before other Toshiba utilities.
