I have a Hewlett Packard Pavilion 741uk Desktop PC and i need to know what system board it uses to update the BIOS. Where can i get this info? I can see nothing on the board itself, and windows tells me very little as well. Where can i find out? I would contact HP but phone line is always heavily queued and open limited hours and i can't get away with making personal calls at work! They won’t respond to this question by e-mail Help!
