Dead Duemilanove

Hello,

My laptop has no serial ports at all, my mouse (touch pad) is a PS2, I have checked and double checked, the port is 100% COM1, the port is not the issue, I have bought another chip to swap with the Duemilanove but that will not be with me till tomorrow the earliest, and I will let you know how it go's, other then that, how can I flash a new bootloader ?

Thanks
