Since I updated my BIOS to Coreboot/Heads (I flashed a prebuild image externally), my Wi-Fi card is not recognized by lspci/iwconfig (even in the Heads recovery shell).
I tried so far:
flashing a different maximized Heads board
using a different PCIe slot (both are not recognizing it)
using a different Wi-Fi card
testing the Wi-Fi card on a different system (successfully)
tried the Wi-Fi troubleshooting guide before
lspci won’t show it (even in the Heads recovery shell)
Is there a way to activate the Wi-Fi cards in Heads? (like mentioned in the Wi-Fi troubleshooting guide)
How can I check if my PCIe slots work?
