I would recommend the lists be retained. Presumably the individual(s) that wrote the CPU / northbridge support code are aware of the CPUs that the code is designed to work with, and using CPUs that were never intended with that code does entail a certain amount of risk. Individuals capable of mitigating this risk / verifying processor functionality are also capable of modifying the CPUID list. - -- 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/ iQEcBAEBAgAGBQJYrht0AAoJEK+E3vEXDOFb/S0H/17w88+kNxBcPm+V+hPkpMDE r6FcyfSO4tm96b/lPgkhK78jxqighQHD7sR2keFWAO+5hwRQfuZwHYVsPa1WmrUN u3J08Mgl5r/xTyoBEp/CRxAGD5FaN+NOYQgBVFh8J6IGLBeYJxcmv/PdQmctvi+J lXuqepsei5TLDIn+9hE3U2Dbh0H/6m8+YFFRbeYbcoNfyuRFE5APks3s+QOjqa4w wBR30fafSBkj4DyGMSzD5yZbOLl/SJDhT1FjvWlx5H4YwKv/vltAPYhq1enaJkRf 61cpl2Prfin4DvpWGU/geTi94bskBo8D8sE1SHumoGXIQ+maICPh/ndtIRNUJIQ= =UsCc -----END PGP SIGNATURE----- -- coreboot mailing list: coreboot@coreboot.org https://www.coreboot.org/mailman/listinfo/coreboot
