How to download bios update for dell dimension 9150

[jiel22]

hey guys, i have a dell dimension 9150 and i wanted to update ithe bios, but when i go to dell support in their website they can't recognize my computer and i don't have the product id too, and if i manually choose for the product for downloading bios updates there is no Dimension 9150 there, only Dimension 9150 XPS 400, are they the same? where can i download the latest update for Dimension 9150?

thanks in advance =)
