Surely you can if you leave the original cpu in the server, or how do
you ever upgrade the bios?


I have an MSI Tomahawk Max (Ryzen) motherboard which can flash its BIOS
without a CPU or RAM installed. It only needs a power supply connected.


I have an Asus motherboard (Intel CPU), with the same feature.
Board does not need a CPU or RAM, to upgrade the BIOS.
Place a BIOS file on a USB stick, plug in USB stick,
push the button, it flashes up the BIOS chip. The USB
slot has a white tab, indicating it is different than the
slots above it.

Since many mobos support this, (and for good reason such as building
with a newer CPU that requires bios update for support), then I sand by
my statement that 'As with all things "Secure [whatever]" has nothing to
do with security and everything to do with vendor-lock-in.'
