Unknown. I would imagine there is a hack in the vendor BIOS to work around this board-specific issue, but that doesn't help coreboot very much. We had looked into it before, but decided it was not worth the cost to research and implement a fix. For what it's worth, there are several threads online about the KGPE-D16 and memory corruption with the vendor BIOS. It seems to have taken ASUS some time to iterate and work around the problem. - -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 (direct line) +1 (512) 690-0200 (switchboard) https://www.raptorengineering.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJYjj6vAAoJEK+E3vEXDOFbbH8H/RarB/ky7zMKzZrWnYJgsieD bEA7RXdCQyBU8w44QOswMbdaM61e4V4luwklJlCUSMgsCfuABHNgoR9v1C1u9E1b Q5AKj0FJzUgET1Eb+dBfN7VAVG1ezhJkPHXqRJI9MPkKsmwlAXrYynaZqS6x8AZE q4a0VYqWyckDTECti+kjgGwN5EyPEy+Mg+9ic1tSn8ItjIlV8ztpvmTUy2d56B+R wr4RKDM8WBWOMQm2itPVKAoeM7KA3ewJ2ZkpLG1cGmUMOjIMPyjlEKPKchBbpmvk zoPBhyJSDbbcMoAWp4h2813pVWWDxCufmcGlINZSwztmKkhXWgRDDnRlH7J6PRs= =EcKb -----END PGP SIGNATURE----- -- coreboot mailing list: coreboot@coreboot.org https://www.coreboot.org/mailman/listinfo/coreboot
