CMOS Reset after upgrading to El Capitan

Hi there guys and girls.

I've recently upgraded to El Capitan and now whenever i shut down or reboot my laptop, it loses it's BIOS settings. The clover patch is not working, neither is the multibeast patch or the terminal patch. (Oh and DSDT is patched)

Has anyone got any ideas about how to go about fixing this?

Many thanks.

(Btw i'm booting legacy)

I'm having the same problem. Its quite annoying for me as I have an ssd with 10.10, and an ssd with 10.11, and the by default in the bios, the 10.10 ssd boots, and I need it the other way around. I also don't want speedstep enabled.

Any help would be appreciated.
