 ======= General Information =======
+The ASUS KGPE-D16, //often referred to as "D16"//, is the [[hardware:kcma-d8|KCMA-D8]]'s "bigger brother" in a larger SSI-EEB board configuration (ATX configuration on the KCMA-D8) and AMD's G34 socket (socket C32 on the KCMA-D8). Southbridge/northbridge and platform are similar to the KCMA-D8; both had been ported to coreboot (initial efforts by [[https://www.raptorengineering.com/|Raptor Engineering, Inc.]]) with only small differences in source code.
 The ASUS KGPE-D16 is a AMD Family 10h/15h, dual-CPU server and workstation motherboard released end of 2012. With a dual CPU setup the performance is still impressive today for a target that doesn't require binary blobs to operate. It is stable coreboot target (but has been dropped from coreboot end of 2019 with 4.11 being the latest release that can be used). For some minor caveats please see information below.

 Incidentally, this design places the IOMMU, which is part of the SR5690, in the correct location to properly shield the main CPU from all unauthorized traffic. If the southbridge connected directly to a HyperTransport link there would be no way to prevent unauthorized DMA from legacy PCI devices connected to the southbridge, or even from the southbridge's embedded microprocessor.

 ==== Specific notes regarding fancontrol on KGPE-D16 ====
-=== openBMC Port on KGPE-D16 ===
+===== openBMC Port on KGPE-D16 =====
 Install the OpenBMC port beta to the ASMB4-iKVM or ASMB5-iKVM modules that come with the main KGPE-D16 retail SKU, this provides fan control and a variety of other cool remote management features.
-=== Limited thermal management with coreboot and coreboot-based BIOS replacements on KGPE-D16 ===
+==== Limited thermal management with coreboot and coreboot-based BIOS replacements on KGPE-D16 ====
 The thermal management hardware of the KGPE-D16 is somewhat unusual and limited. It supports both 4-pin and 3-pin fans, however even though it contains a PWM controller with 8 hardware channels, ASUS has only wired up two PWM channels to the fan connectors. To make matters worse, PWM channel 1 is routed to all 4-pin fans while PWM channel 2 is routed to all 3-pin fans.

 ===== Miscellaneous Known Issues and Workarounds =====
@@ Line 152: / Line 201: @@
 If your KGPE-D16 server or workstation is equipped with a discrete graphics processor, the on-board VGA is disabled. Petitboot builds of Vikings do not have drivers for most discrete graphics processors, so there is no boot screen on which to select boot media, for example. Your display should start working as soon as Linux from an installed drive has been loaded.
-A workaround for this is to enable the VGA jumper and connect a screen to the on-board VGA output because Petitboot has the required drivers for the on-board GPU (Aspeed AST2050) included. This is useful when installing a new operating system for example. The jumper settings can be reverted afterwards. {{KGPE-D16_VGA_controller_jumper.png|KGPE-D16 VGA Jumper}}
