Those can only be disabled through BIOS, those are the sort of advertising ones.. like on Sony VAIO laptops it shows a Sony animation, and on allot of ASUS boards it shows an ASUS logo when it should show all specs (mem,cpu,hd,cd-rom).. The options vary for each different brand, so best is just to go and hit delete when u see the screen, then when its in bios, go through all pages and find something named like "Show splash screen" or "Show logo on boot up".. check it out, wont be too hard..
