+.Sh NAME
+.Nm boot_zaurus
+.Nd zaurus system bootstrapping procedures
+.Sh DESCRIPTION
+.Ss System starts
+When powered on, or if the system is rebooted via
+.Xr reboot 8
+or
+.Xr shutdown 8 ,
+the processor begins executing code at physical address 0.
+The early startup code is preinstalled by the manufacturer,
+and will load a minimal UNIX-like operating system from internal
+flash memory (our primary bootstrap loader, for now).
+.Ss Boot process options
+On most systems, booting
+.Ox
+from the primary bootstrap loader will eventually load the
+.Ox Ns -specific
+zaurus bootstrapping code.
+This versatile program is described in a separate document,
+.Xr boot 8 .
+.Ss Abnormal system termination
+In case of system crashes, the kernel will usually enter the kernel
+debugger,
+.Xr ddb 4 ,
+unless it is not present in the kernel, or it is disabled via the
+.Em ddb.panic
+sysctl.
+Upon leaving ddb, or if ddb was not entered, the kernel will halt the system
+if it was still in device configuration phase, or attempt a dump to the
+configured dump device, if possible.
+The crash dump will then be recovered by
+.Xr savecore 8
+during the next multi-user boot cycle.
+It is also possible to force other behaviours from ddb.
