So i been planning on building a new PC. My main plan is to get an Intel Core i5-9600k and a Asus Strix B360-I, but in Pcpartpicker it says " Some Intel B360 chipset motherboards may need a BIOS update prior to using Coffee Lake Refresh CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions." my friend told me that I can simply update the BIOS with a flash drive and no CPU. I just wanted to get confirmation that this process works?
