+title: ASUS KCMA-D8 desktop/workstation board
+...
+
+This is a desktop board using AMD hardware (Fam10h *and Fam15h* CPUs
+available). It can also be used for building a high-powered workstation.
+Powered by libreboot. The coreboot port was done by Timothy Pearson of
+Raptor Engineering Inc. and, working with them, merged into libreboot.
+
+*Memory initialization is still problematic, for some modules. We
+recommend avoiding Kingston modules.*
+
+Flashing instructions can be found at
+[../install/\#flashrom](../install/#flashrom) - note that external
+flashing is required (e.g. BBB), if the proprietary (ASUS) firmware is
+currently installed. If you already have libreboot, by default it is
+possible to re-flash using software running in GNU+Linux on the kcma-d8,
+without using external hardware.
+
+CPU compatibility
+=================
+
+*Use Opteron 4200 series (works without microcode updates, including hw
+virt).* 4300 series needs microcode updates, so avoid those CPUs. 4100
+series is too old, and mostly untested.
+
+Board status (compatibility) {#boardstatus}
+============================
+
+See <https://raptorengineeringinc.com/coreboot/kcma-d8-status.php>.
+
+Form factor {#formfactor}
+===========
+
+This board is ATX form factor. While the [ATX standard, version 2.2](https://web.archive.org/web/20120725150314/http://www.formfactors.org/developer/specs/atx2_2.pdf)
+specifies board dimensions 305mm x 244mm, this board measures 305mm x 253mm;
+ensure your case supports this extra ~centimeter in width.
+
+IPMI iKVM module add-on {#ipmi}
+=======================
+
+Don't use it. It uses proprietary firmware and adds a backdoor (remote
+out-of-band management chip, similar to the [Intel Management
+Engine](../../faq.md#intelme). Fortunately, the firmware is
+unsigned (possibly to replace) and physically separate from the
+mainboard since it's on the add-on module, which you don't have to
+install.
+
+Flash chips {#flashchips}
+===========
+
+2MiB flash chips are included by default, on these boards. It's on a
+P-DIP 8 slot (SPI chip). The flash chip can be upgraded to higher sizes:
+4MiB, 8MiB or 16MiB. With at least 8MiB, you could feasibly fit a
+compressed linux+initramfs image (BusyBox+Linux system) into CBFS and
+boot that, loading it into memory.
+
+Libreboot has configs for 2, 4, 8 and 16 MiB flash chip sizes (default
+flash chip is 2MiB).
+
+*DO NOT hot-swap the chip with your bare hands. Use a P-DIP 8 chip
+extractor. These can be found online. See
+<http://www.coreboot.org/Developer_Manual/Tools#Chip_removal_tools>*
+
+Native graphics initialization {#graphics}
+==============================
+
+Only text-mode is known to work, but linux(kernel) can initialize the
+framebuffer display (if it has KMS - kernel mode setting).
+
+Current issues {#issues}
+==============
+
+- LRDIMM memory modules are currently incompatible
+- SAS (via PIKE 2008 module) requires non-free option ROM (and
+ SeaBIOS) to boot from it (theoretically possible to replace, but you
+ can put a kernel in CBFS or on SATA and use that to boot GNU, which
+ can be on a SAS drive. The linux kernel can use those SAS drives
+ (via PIKE module) without an option ROM).
+
+- IPMI iKVM module (optional add-on card) uses proprietary firmware.
+ Since it's for remote out-of-band management, it's theoretically a
+ backdoor similar to the Intel Management Engine. Fortunately, unlike
+ the ME, this firmware is unsigned which means that a free
+ replacement is theoretically possible. For now, the libreboot
+ project recommends not installing the module. [This
+ project](https://github.com/facebook/openbmc) might be interesting
+ to derive from, for those who want to work on a free replacement. In
+ practise, out-of-band management isn't very useful anyway (or at
+ the very least, it's not a major inconvenience to not have it).
+- Graphics: only text-mode works. See [\#graphics](#graphics)
