title: ASUS KGPE-D16 server/workstation board
x-toc-enable: true
...
TODO: OLD page. TODO: check that all the info is still valid.
Introduction
This is a server 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 (and sponsoring the
work), merged into libreboot.
Memory initialization is still problematic, for some modules. We
recommend avoiding Kingston modules.
For working configurations see https://www.coreboot.org/Board:asus/kgpe-d16.
Flashing instructions can be found at
../install/#flashprog - note that external
flashing is required, 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 Linux on the
KGPE-D16, without using external hardware.
CPU compatibility
Opteron 62xx and 63xx CPUs work just fine.
Board status (compatibility) {#boardstatus}
See https://raptorengineeringinc.com/coreboot/kgpe-d16-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. 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
This guide shows how to flash the chip:\

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
(IT MAY WORK NOWADAYS, TODO TEST)
- SAS (via PIKE 2008 module) requires a vendor option ROM (and
SeaBIOS) to boot from it (theoretically possible to replace, but you
can put a kernel in CBFS or on SATA and boot from that, which
can be on a SAS drive. The linux kernel can use those SAS drives
(via PIKE module) without an option ROM).
- SeaBIOS lacked serial console support out-of-the-box in release 20160907
and as such a workaround using SGABIOS is necessary. You can find
instructions on how to do this on the
Notabug issue tracker
- 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 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
