#define quoting(Bruce Evans) // Summary of the 3 cases where the whole disk is used for FreeBSD: // // Partition table config Slice# passed by bootblocks Slice# to use for "/" // ---------------------- --------------------------- ------------------------- // Signature != 0xAA55 WHOLE_DISK_SLICE (= 1) COMPATIBILITY_SLICE (= 0) // Historical invalid BASE_SLICE + 3 (= 5) COMPATIBILITY_SLICE (= 0) // "Valid" (1 big part.) BASE_SLICE + N (0 <= N < 4) BASE_SLICE + N // // User actions in the 3 cases: // 1. Hope this doesn't happen. It is very unlikely to happen for boot disks. Most PC BIOSes (if not all) will not boot from a disk if the first block does not have the 0xAA55 signature. Indeed, they will not boot without a valid MBR. Have you ever seen such a case ? Or does this discussion apply to PC98 (from which I have no info, and don't know if the above is still true) and Alpha ports ? // 2. Wait for fixes. // 3. Same as for cases where the whole disk is not used for FreeBSD - edit // /etc/fstab.
