GPTBOOT 8 -.Os -.Sh NAME -.Nm gptboot -.Nd GPT bootcode for UFS on BIOS-based computers -.Sh DESCRIPTION -.Nm -is used on BIOS-based computers to boot from a UFS partition on a -GPT-partitioned disk. -.Nm -is installed in a -.Cm freebsd-boot -partition with -.Xr gpart 8 . -.Sh IMPLEMENTATION NOTES -The GPT standard allows a variable number of partitions, but -.Nm -only boots from tables with 128 partitions or less. -.Sh PARTITION ATTRIBUTES -.Nm -checks and manages several attributes of GPT UFS partitions. -.Bl -tag -width ".Cm bootfailed" -.It Cm bootme -Attempt to boot from this partition. -If more than one partition has the -.Cm bootme -attribute set, -.Nm -will attempt to boot each one until successful. -.It Cm bootonce -Attempt to boot from this partition only one time. -Setting this attribute with -.Xr gpart 8 -automatically also sets the -.Cm bootme -attribute. -Multiple partitions may have the -.Cm bootonce -and -.Cm bootme -attributes set. -.It Cm bootfailed -The -.Cm bootfailed -attribute marks partitions that had the -.Cm bootonce -attribute set, but failed to boot. -This attribute is managed by the system. -See -.Sx "BOOTING" -and -.Sx "POST-BOOT ACTIONS" -below for details. -.El -.Sh USAGE -For normal usage, the user does not have to set or manage any of the -partition attributes. -.Nm -will boot from the first UFS partition found. -.Pp -The -.Cm bootonce -attribute can be used for testing an upgraded operating system on -an already-working computer. -The existing system partition is left untouched, and the new version -of the operating system to be tested is installed on another partition. -The -.Cm bootonce -attribute is set on that new test partition. -The next boot is attempted from the test partition. -Success or failure will be shown in the system log files. -After a successful boot of the test partition, a user script can check -the logs and change the -.Cm bootme -attributes so the test partition becomes the new system partition. -Because the -.Cm bootonce -attribute is cleared after an attempted boot, a failed boot will not -leave the system attempting to boot from a partition that will never -succeed. -Instead, the system will boot from the older, known-working operating -system that has not been modified. -If the -.Cm bootme -attribute is set on any partitions, booting will be attempted from them -first. -If no partitions with -.Cm bootme -attributes are found, booting will be attempted from the first UFS -partition found. -.Sh BOOTING -.Nm -first reads the partition table. -All -.Cm freebsd-ufs -partitions with only the -.Cm bootonce -attribute set, indicating a failed boot, are set to -.Cm bootfailed . -.Nm -then scans through all of the -.Cm freebsd-ufs -partitions. -Boot behavior depends on the combination of -.Cm bootme -and -.Cm bootonce -attributes set on those partitions. -.Bl -tag -width ".Cm bootonce + .Cm bootme" -.It Cm bootonce + Cm bootme -Highest priority: booting is attempted from each of the -.Cm freebsd-ufs -partitions with both of these attributes. -On each partition, the -.Cm bootme -attribute is removed and the boot attempted. -.It Cm bootme -Middle priority: booting is attempted from each of the -.Cm freebsd-ufs -partitions with the -.Cm bootme -attribute. -.El -.Pp -If neither -.Cm bootonce -nor -.Cm bootme -attributes are found on any partitions, booting is attempted from the -first -.Cm freebsd-ufs -partition on the disk. -.Sh POST-BOOT ACTIONS -The startup script -.Pa /etc/rc.d/gptboot -checks the attributes of -.Cm freebsd-ufs -partitions on all GPT disks. -Partitions with the -.Cm bootfailed -attribute generate a -.Dq boot from X failed -system log message. -Partitions with only the -.Cm bootonce -attribute, indicating a partition that successfully booted, generate a -.Dq boot from X succeeded -system log message. -The -.Cm bootfailed -attributes are cleared from all the partitions. -The -.Cm bootonce -attribute is cleared from the partition that successfully booted. -There is normally only one of these. -.Sh FILES -.Bl -tag -width /boot/gptboot -compact -.It Pa /boot/gptboot -bootcode binary -.It Pa /boot.config -parameters for
