Follow the links and then make sure you download the FLOPPY disk version. Go to the directory that you saved the BIOS file in using Windows Explorer. Then power it back up with the floppy disk that you just created with the BIOS on it. When you power the computer up, it will automatically load the program to flash your BIOS.

If for some reason the tests are unsuccessful, the computer would emit a series of beeps with an error message and code.
