For example, if you are still running a Core i7-4970K 'Devil's Canyon' CPU in a Z97-chipset motherboard, you are out of luck for the time being, at least as it pertains to a BIOS update.It remains to be seen if motherboard makers will go that far back, and beyond.You can enter the system BIOS or Setup on a Dell PC by pressing F2 at the Dell loading screen.(Figure 1) Figure 1: BIOS Loading Screen Or by pressing F12 and selecting BIOS Setup from the menu.We are diligently working to update ASUS motherboards that support 6th, 7th or 8th Generation Intel Core processors or Intel Core X-series processors for X99 and X299 platforms.We recommend customers update their systems by downloading and applying the latest BIOS, as soon as the relevant revision becomes available," ASUS said in a statement.BIOS is an acronym that stands for Basic Input Output System.Also know as "System Setup", the BIOS is software that is contained on a small memory chip on the PC's Motherboard, typically referred to as the CMOS (Complementary Metal Oxide Semiconductor).
As companies scramble to mitigate Meltdown and Spectre, you should be planning for Patch January, and maybe February as well.
This is called the ESCD (Extended System Configuration Data) and this is usually stored in additional non-volatile memory also referred to as NVRAM (Non-Volatile Random Access Memory) Over the years as technology has changed people still refer to the BIOS as both CMOS and NVRAM, however they are subtly different.
The CMOS contains the BIOS and its settings, the NVRAM contains the ESCD, updating the BIOS will not clear the NVRAM.
There are way too many models for us to link directly to each one individually, but if you go here, you will find the latest BIOS version available for well over 100 models cover the X299, Z370, Z270, Z170, B150, B250, H270, H110, Q170, Q270, and X99 chipsets.
Cross reference that information with the latest BIOS update available in the support section of your motherboard's product page.
