+This hardware is considered legacy. It holds historical significance for older systems that remain relevant for specific use cases despite their age.  It may still be useful for specific purposes, such as coreboot, FSF RYF, retrofitting, or historical reference.

-The ASUS KCMA-D8, //often referred to as D8//, is the [[hardware:kgpe-d16|KGPE-D16]]'s "little brother" with a smaller, ATX board format and AMD's C32 socket (instead of the G34 socket for the KGPE-D16. Southbridge/northbridge and platform are similar to the KGPE-D16; both had been ported to coreboot with only small differences in source code.
+===== General information =====
+The ASUS KCMA-D8, //often referred to as "D8"//, is the [[hardware:kgpe-d16|KGPE-D16]]'s "little brother" in a smaller ATX board configuration (SSI-EEB configuration on the KGPE-D16) and AMD's C32 socket (socket G34 on the KGPE-D16). Southbridge/northbridge and platform are similar to the KGPE-D16; both had been ported to coreboot (initial efforts by [[https://www.raptorengineering.com/|Raptor Engineering, Inc.]]) with only small differences in source code.
 It is also useful for a router/firewall or secure applications device as it has an IOMMU and compatible low wattage CPU's such as the 35W Opteron 42xxEE series.

+===== CPU HCL =====
-==== CPU HCL ====
+The ASUS KCMA-D8 mainboard is compatible with all available Opteron 4100 CPUs and depending on the board revision also with all available Opteron 4200/4300 CPUs (see information below).
-The ASUS KCMA-D8 mainboard is compatible with the Opteron 4100 CPUs and depending on the board revision also with Opteron 4200/4300 CPUs. **Vikings only sells KCMA-D8 mainboards compatible with the Opteron 4200/4300 CPUs.**
+==== Opteron 4100 not recommended ====
-=== Opteron 4100 not recommended ===
 While working it is not recommended; IOMMU missing. In addition, it has not yet been tested; it may or may not work.
-=== Opteron 4200/4300 recommended ===
+==== Opteron 4200/4300 recommended ====
-The Opteron 4200/4300 series only work with board revisions starting with specific board revision/serial number/BIOS version.
+=== Opteron 4200 ===
-Be aware that other sources of hardware (ebay, aliexpress etc.) may ship you an older, unusable board. Make sure to inquire prior purchasing from sellers you don't trust.
+The Opteron 4200 series CPUs works well, even without CPU microcode updates and with hardware virtualization.
+=== Opteron 4300 ===
-**Vikings only sells KCMA-D8 mainboards compatible with the Opteron 4200/4300 CPUs**.
+The Opteron 4300 series CPUs also work well, are faster than their Opteron 4200 counterparts and may offer more CPU flags. However they require CPU microcode updates for stable operation.
-== How to verify if Opteron 4200/4300 is working with your board ==
+==== BIOS version 2001 (or later) required for Opteron 4200/4300 ====
-The serial number //B9S2xxxxxxxx// or above is required. B means year, B=2011, C=2012…; 9 means month, 1...9, A, B, C.
+The Opteron 4200/4300 series only work with board revisions starting with specific board revision/serial number/BIOS version:
+The serial number //B9S2*// or above is required. B means year, B=2011, C=2012…; 9 means month, 1...9, A, B, C.
 The sticker with the serial number is located on the ATXPWR1 24-pin power connector.
-= BIOS version 2001 (or later) required =
+If your boards serial number is //B9S2*// or above, verify that BIOS version 2001 (or later) is installed. Otherwise please update your BIOS: http://www.asus.com/Server_Workstation/Server_Motherboards/KCMAD8/#download
-If your boards serial number is //B9S2xxxxxxxx// or above, verify that BIOS version 2001 (or later) is installed. Otherwise please update your BIOS: http://www.asus.com/Server_Workstation/Server_Motherboards/KCMAD8/#download
