ok ive got leopard 10.6.1 installed on my Toshiba Equium A100-338 laptop, but natraly the sound and my wifi arnt working

my sound is most likely controled by my chipset which is the intel 945GM Express chipset

and my wifi is a Intel® PRO/Wireless 3945ABG network connection

any ideas on how to get these to work

im thinking about upgradeing to snow leopard in a while
