I've followed the video perfectly but still get the following:

Clock Frequency (External) = 24.0000MHz, Clock Mode = 0, CKM = 1, and CKP = N/A

Error No 15024: Boot failed

MY Serial port is enabled in my BIOS, tried AUTO and tried different IRQs. Tried setting different Com settings: 1, 2, 6. I know it enters boot mode because of no lights. I am using a standard serial cable with a gender changer because the cable I have is female to female.
