Patch set updated for coreboot: mainboard/intel/d510mo: Add Intel D510MO mainboard
by Damien Zammit 24 Nov '15

24 Nov '15

Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10074 -gerrit commit fcafd45b818ea7d815ed6368684896e17b79c3de Author: Damien Zammit <damien(a)zamaudio.com> Date: Mon May 4 10:41:21 2015 +1000 mainboard/intel/d510mo: Add Intel D510MO mainboard Board uses Pineview native raminit Board boots grub -> linux kernel NB: For fully functional board, this currently needs patch: 6311, otherwise board gets stuck on parallel SMI init. VGA needs work, currently headless machine.

Patch set updated for coreboot: mainboard/intel/d510mo: Add Intel D510MO mainboard
by Damien Zammit 24 Nov '15

24 Nov '15

Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10074 -gerrit commit 333f3b713bbf4a7d981736d4e708b2605b6dda4f Author: Damien Zammit <damien(a)zamaudio.com> Date: Mon May 4 10:41:21 2015 +1000 mainboard/intel/d510mo: Add Intel D510MO mainboard Board uses Pineview native raminit Board boots grub -> linux kernel NB: For fully functional board, this currently needs patch: 6311, otherwise board gets stuck on parallel SMI init. VGA needs work, currently headless machine.
