Yes, probably - but don't forget that the normal user way of 'reflashing the BIOS' is to tell the BIOS to reflash a new image; so in theory (but hard) a malicious BIOS could keep itself in there. If you used JTAG etc to reflash the BIOS externally then yes you could probably clear it out.
- telgareith 2y agoSome (most?) motherboards now have a way to reflash a bios in "no POST" scenarios. There's either a dedicated microcontroller or it reuses the embedded controller to read a BIOS image from a USB mass storage device. It works even when there's no CPU installed.
