Accessing BIOS Default Settings

[BLToaster]

Hi, I have an HP 2000-354NR Notebook laptop and am trying to gain access to the BIOS settings in order to change some of my RAM (4 GB) over to the dedicated video RAM which is currently only at 64 MB. When I access the BIOS settings from the startup menu all of the default settings are greyed out and does not allow me to edit them on the initial page.

If someone could help me out and how I can gain access to these settings or how else I can accomplish what I am trying to do I would greatly appreciate it!
