I replaced mobo my old one was broken. When installing I unplaged bios battery. At the end when all was done I pluged the battery again and now I got the message about impproper time/date and after that Im asked to enter password on black screen. No way to boot up OS.
Any help?

It looks like the replacement mobo has a supervisor PW, Get it from whoever sold it to you, or get a refund. You have no real other choice. That's NOT a user PW prompt, and anything further is not allowed for discussion on these boards.
