The BIOS password is not a problem. Some motherboards have a jumper to reset. Don't know about the Chaintech mobo but look on the board and there should be a 3 pin jumper. Pins 1 and 2 reset the BIOS. Just take the jumper off pins 2 and 3 and put them on pins 1 and 2 and leave for a few seconds and then put them back on pins 2 and 3 and the password should be taken off. If that doesn't work, or if there are no jumpers remove the mobo battery for a few minutes and then replace it and then switch on.
