Replaced Failed Motherboard.. now how do I determine model number and which BIOS to download?

Had an AMD HP G62-227CL laptop that overheated and required motherboard replacement with similar Intel motherboard. Old board clocked at 2.2 MHZ .. new one is 2.0 MHZ.
Board I got from Ebay works but now computer believes that it is a Compaq CQ42 Laptop. Do not know the model number, which I would need on HPs site to download BIOs upgrades.

Is there a way to tell which bios I need or what model I now have?

Thank you,

Steve
