-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}
-===========
-
-These boards use the SSI EEB 3.61 form factor; make sure that your case
-supports this. This form factor is similar to E-ATX in that the size is
-identical, but the position of the screws are different.
-
-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/#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)
