Need a way to change Bios settings with a controlled reboot

Hi,

I need a way to programatically change bios settings and be able to reboot the server myself - rather than the utility.  For example, if I use RACADM to change the bios settings, it will automatically reboot the server which messes up my automation. 

Does anyone know how to programatically perform bios setting changes while being able to control when the server is rebooted?

Thanks
