Hello nrsoto2003, and randyored,
If you need to update your Bios, take a look here. HP and Compaq Desktop PCs*-* Updating the BIOS*
I don't know how much you will be able to change in your Bios as most manufactures tend to lock their Bios.
If everything is set at default in the Bios then it should compensate for the new memory.
Please remember that updating the Bios, can be fraught with danger.
If there is an option to use Windows to update the Bios don't use it, go to the Bios and update it from there.
Hope this helps, good luck and post your results.
