It works rather well, no need to remove CMOS battery for instance (if no picture/boot, just disconnect PSU for a sec and restart). Small annoyance is that the computer won't start with USB _storage_ attached (so instead, you should disconnect these and reconnect when grub is shown). It is a good machine for every day use (free firmware & 32 cores and 64GB DDR3 ECC RAM), and possible to find used starting at 5k = 3k+1k+1k (motherboard+cpu&cooler+ram), remember that external GPU and sound cards will be needed. The single-thread performance is rubbish and a major bottleneck for certain applications (no you can't play CS:GO or other modern video games, and only slight performance gain can be achieved by forcing all threads to highest clock in Linux with cpupower). The other downside is that the dual CPU system draws ~200 watts IN IDLE (and 400w at full load). -#### General +### General Also Raptor Engineering was working on new free features (OpenBMC, IPMI, and Thermal management drivers) for this board, [here](https://www.raptorengineering.com/coreboot/kgpe-d16-bmc-port-status.php). @@ -341,30 +380,30 @@ Also Raptor Engineering was working on new free features (OpenBMC, IPMI, and The * Note: It is necessary to have a dedicated sound card and graphics card, _if_ those features are desired. -#### Using +### Using * Both GRUB and SeaBIOS work.

Suddenly, USB ports does not work, such as the chassi's USB hub which is connected on the moderboard. These are completely dead and the peripheral devices does not light up. Only rebooting does not help. **Solution**, turn off computer and disconnect power (we did not need to clear CMOS), and disconnect the problematic USB stick on the back. Turn on power. The USB stick can now be plugged in when the hardware has been initialized and GRUB is shown. -#### Quirks with earlier GRUB version +### Quirks with earlier GRUB version * Sometimes we get an error when booting, this is resolved by disconnecting USD devices such as keyboard and mouse until the hardware is initiated. * In GRUB the USB keyboard is sometimes unusably slow.
