I want to change the settings on the BIOS but when I get into the BIOS at start up the only settings I can see are the boot choices. The 1st setting is the floppy drive but I want to change it to the CD drive. However, there is no way to do this. I can arrow down to the drive but there is no way of promoting it to be the main boot device. When I arrow down and press enter the computer just boots.
