The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=e5d1a21e500142c02fd44ce2f7822f2815a74fcc commit e5d1a21e500142c02fd44ce2f7822f2815a74fcc Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2024-02-16 04:12:52 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-02-16 04:16:36 +0000 loader: Bump the limit to 560,000 bytes for BIOS loader Further experience suggests we do not need as much margin.
