The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=34d55be0747ba4452f9611ca88fe21e9d94be266 commit 34d55be0747ba4452f9611ca88fe21e9d94be266 Author: Ed Maste <emaste@FreeBSD.org> AuthorDate: 2023-08-15 22:42:22 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2023-08-15 22:45:58 +0000 boot0: add a note about BIOS-supported serial rates We plan to increase the default serial rate to 115200 (see review D36295) but early boot components that use BIOS interfaces do not support higher rates. Add a note to that effect.
