The BIOS updates patch up the latest vulnerabilities in the Intel processor. The downside to that is it does cause a performance hit which varies depending on what source you watch/read. There is no way to downgrade the BIOS once you have patched this in.

 Hi 

 You can rollback to the previous BIOS version (no interest if the previous one was 1.2.3) by doing so :

Unplugg AC power, 
HIT CTRL-ESC for few seconds
plug AC and power on
HIT F2 -> a specific BIOS menu will appear on which you will see "Rollback to previous Version" Menu

NB / there is only one previous version
