I have a Asus z87-Deluxe* It currently has bios version: 1602 but there is an update to 1802 I simply want to change the splash screen. What tool do I use please? (I'm running win 8.1) I'm guessing once modified I can simply use Asus's own updater to flash the new bios? Thanks *(.asus.com/uk/Motherboards/Z87DELUXE/#support)
