Agreed w/spyhunter. Most likely your windows 2000 (pro?) install is using 'generic' VGA drivers, which only give you basic functionality.
Once you install the driver disc everything should be fine, if you cant find it then post the model number of the laptop here and we'll help you find it.
We can also get some details about your onboard card using debug.exe (-d c000:0080) - but its easier to ask for the model number lol
