 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.
