+@deffn Command disk_set @var{flag} @var{state}

+Changes a flag on the disk.  A flag can be either ``on'' or ``off''.
+Some or all of these flags will be available, depending on what disk
+label you are using:
+
+@table @samp
+
+@item pmbr_boot
+(GPT) - this flag enables the boot flag on the GPT's protective MBR
+partition.
+
+@end table
+
+The disk's flags are displayed by the print command on the "Disk Flags:"
+line.  They are also output as the last field of the disk information
+in machine mode.
