Please teach me about how to find drivers and how to install drivers.

["Kyuichiro Nakamura" <q-nakamura@kne.biglobe.ne.jp>]

Sir,I am just started to install Debian Linux on my old 
DynaBook SS 60P 1N8M (192Mb).
I can not search for drivers.
I also can not install the drivers.
I am intending to use application 'ORCA' for my doctor.
Which is developped for Debian Linux.
I also bought a magazine titled 'Super simple introduction to Linux'.
I tried to run UBUNTU live on the same PC.
But it hung upped.
