I'm upgrading an old computer (Dell Dimension 4100). I'm putting in a new HD 120GB among other things. My current BIOS is a A02 and I need to update it to A11. I went to the support.dell.com site and it gives me two options to download the update onto a floppy. Is there an easier way? Can someone give me directions on how to update the BIOS. I downloaded the information on a disk but I don't know what to do next. Thank you.
