BOOT_ZAURUS(8)     OpenBSD System Manager's Manual (Zaurus)     BOOT_ZAURUS(8)

NAME
     boot_zaurus - zaurus system bootstrapping procedures

DESCRIPTION
   System starts
     When powered on, or if the system is rebooted via reboot(8) or
     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 pri-
     mary bootstrap loader, for now).

   Boot process options
     On most systems, booting OpenBSD from the primary bootstrap loader will
     eventually load the OpenBSD-specific zaurus bootstrapping code.  This
     versatile program is described in a separate document, boot(8).

   Abnormal system termination
     In case of system crashes, the kernel will usually enter the kernel de-
     bugger, ddb(4), unless it is not present in the kernel, or it is disabled
     via the 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 savecore(8) during the next multi-
     user boot cycle.  It is also possible to force other behaviours from ddb.
