KGPE-D16
The ASUS KGPE-D16, commonly referred to as the D16, is a dual-socket server/workstation motherboard released by ASUS on April 7th, 2010[1], for use with Socket G34 Opteron processors. Originally sold as a standalone board in a mostly-standard SSI EEB form factor, and intended for both desktop and rack-mounted uses, the KGPE-D16 is popular among enthusiasts as a relatively versatile and workstation-friendly G34 platform.
Ports of Coreboot and OpenBMC to the D16 was developed by Raptor Engineering between 2015 and 2017. Among major Coreboot versions, it was first supported in Coreboot 4.2 in October 2015, and last supported in Coreboot 4.11 in November 2019. Support was dropped beginning in Coreboot 4.12, primarily due to lack of maintenance after Raptor Engineering discontinued work on the platform. Between 2021 and 2022, after seeking funding for such an effort for several years, Dasharo/3mdeb developed an out-of-tree fork of Coreboot 4.15, but it was not upstreamed, and has not been significantly maintained since 2022. At present, there does not appear to be a significant effort to re-upstream the KGPE-D16 into Coreboot.
Most KGPE-D16 owners currently use either upstream Coreboot 4.11, or one of multiple forks of it, such as coreboot-D16 or Libreboot.
