Hi all,
I have two 'quick buttons' on the front pannel of my laptop. In windows it is possible to see the windows driver assigned address to it as from 0x300 to 0x303. Does anybody know whether it is the real physical address? I have done the following:
Code:
while (1)
{
inb(0x300);
inb(0x301);
inb(0x302);
inb(0x303);
}
However no matter how I pushed the bottons, I got 255 on all four addresses. The internal of the laptop, of course, is a manufacturer property, but I don't understand here why I got no response even by inb.
Anybody has any ideas? Thank you very much
