Weird Sound when booting

[EricCamper]

I just had a couple boxes done and they have a high pitch sound when booted for the first time.....Then they flash red..green...yellow a couple of times and it is fine...I flashed with the current 49..... and everything works great....No smoke or grinding metal......just some weird things.... Then when I turn it off...The eject light flashs red for a split second.....And I had to set the date a couple of times in the beginning....But it all seems fine now....Hmmmm..Anyway....Is there a bios or something I can do to change the splashscreen to blue...red....or whatever.....I thought I read that you can make the logo blue....That would be cool....Thanx all......
