    I have 2 same motherboard with same serial number. But when I changed their bios chips they both don't work. Normally when the motherboard works the power supply take 0.45mAH but when I changed the bios chips power supply is changing like 0.20mAH. But when I take the original bios copy and try to use other brand chips to programming it's working . I don't understand what's wrong with that. I was just wondering, are they different even the mainboards are same ? How could I understand it ?
