How do I know which BIOS the system is booting from?
On POST screen, the Boot Bios information will display the BIOS used for this bootup.
I just found the system being booted from the Recovery BIOS, what's next?
With the Recovery BIOS at work, it can be asserted that the Primary BIOS is having such severe problem
that it failed to function. Before you make certain the BIOS chip is completely corrupted, it is definitely
sensible to try the last resort—updating BIOS.
