Hi, isn't Cedarview a processor code name and Cedar Trail platform code name? This presentation mix both: https://manualzz.com/doc/26041007/cedar-trail-platform-bios-session Interesting slide is 21, this lead me to pre-FSP time when BLDK was used and I found this: https://www.intel.pl/content/dam/www/public/us/en/documents/guides/cedar-trail-bldk-get-started-guide.pdf Probably only companies that have CNDA with Intel can still obtain those, but who knows maybe it lays on some server somewhere.
