That is an old Laptop. IBM doesn't even make them anymore, they sold their PC division to Lenovo many years ago.
The one reference I saw was to 2004 for this model. If the 2004 date is correct then probably there are no IBM or Lenovo hardware specific drivers
for either Vista or Win 7 and just whatever generic driver
that Windows installs is probably all that is available.
Look at the Toshiba site and maybe something is there. Many of IBM's laptops were actually made by Toshiba for IBM.
