A slightly off-topic question: many modern motherboard have a function to flash a BIOS even without CPU present (e.g. Gigabyte markets it as Q-Flash). Any idea how does that technically work? Do they put a separate CPU on the motherboard?
I just upgraded to a Ryzen 9 7950x with a Gigabyte x670e motherboard and while using qflash+ I also got curious but nothing online answers how it works and the manual is too simplistic to include the details. If I would have to guess It’s probably the chipset?
smolder has a comment in this thread expressing viability for some boards doing this.
