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.
