The Z820 read from the drive, but I doubt it wrote/changed anything in the bios itself, but at least it wiped the NVRAM clean and the system came back to life. The only way to get it back from a "bricked" state was to switch the crisis recovery jumper and power on with a USB2 thumb drive (smaller than 1GB formatted in MSDOS MBR with a copy of the Bios.bin file in the top directory). also no way to reset the bios, CMOS reset, disconnecting power, etc. The NVRAM gets corrupted and you can get stuck with a black screen, fans spinning but no bios splash screen. ![]() Since it was a new build I decided to give OC a try and found it works but with a big issue.
