- toomuchtodo 11y agoWhatever components start first, wins. If the PXE boot code is in the NIC, you can theoretically verify the rest of the system first. If its in the BIOS, the BIOS needs to trust the NIC as untrusted/determine if its compromised or not. Security is hard :/
- XorNot 11y agoROM based NIC? Why not? If you're going into large scale dedicated servers, this is not exactly impractical. You could probably also just disconnect the flash enable pins on the ICs.
