Just a guess, but I think that the ATI Rage series only support hardware
acceleration if you're at 16 bits per pixel. Otherwise it's done in
software.
(Of course this is not helpful at all if you're already at 16bpp)

I've got the same graphics card he does, and I don't seem to be getting any

This solution is only if you are running the applet locally in a browser.
Otherwise you will probably have to make a URL, etc. to download textures, etc.

If u r trying to read the file from local system, then, no, u can't do
it (unless u grant appropriate permissions like BOL said). But u can read
anything via URL connection, for instance, from the webserver. So, if
u need to read some .txt file with your applet's configuration in it,
then u can do
