To change BIOS boot sequence:
Turn the control on and immediately start tapping on the Del key. Keep tapping on it until the CMOS settings menu appears.
Use the Down arrow key to highlight BIOS (or ADVANCED, depending on your setup program) settings, then press Enter to go to the BIOS settings menu.
In the BIOS menu, use the down arrow to highlight the Boot Sequence item, which is probably currently set to "C,A,SCSI". Use the Pg Up(coolant) key to step through the available selections until you get to "A,C,SCSI" , then press Esc to get back to the main CMOS menu.
Press the F10 key to save the settings and exit.
