... the Installation CD I have
Which installations CD do you have? Do you use original Microsoft disc or some self created disc?
This old Tecra was originally offered with WXP Professional edition SP1 and it is supported for WXP OS. On Toshiba download page you can find all drivers you need.
Clean WXPO installation should not be problem so I would like to know is this “lock up” issue there with clean preinstalled OS without drivers or you have already installed some drivers.
