BOOT(8)              NetBSD/hpcsh System Manager's Manual              BOOT(8)


NAME

     boot -- system bootstrapping procedures


DESCRIPTION

     Windows CE machines with SuperH CPUs use the hpcboot(8) program to boot
     NetBSD.  Once running, NetBSD can reboot itself if kloader(4) is config-
     ured in the kernel.

   Power fail and crash recovery
     Unfortunately, NetBSD can't reboot itself at power-up or after crashes.
     The machine will go through the cold reset and boot into Windows CE.  You
     will have to restart NetBSD manually using hpcboot(8).

     Once NetBSD starts, an automatic consistency check of the file systems
     will be performed, and unless this fails, the system will resume multi-
     user operations.

   Cold starts
     On cold reset Windows CE handheld machines attempt to boot the Windows CE
     operating system from the boot ROM.  The boot ROM is usually not
     rewritable, so you cannot erase or damage Windows CE image.

     You can't boot NetBSD directly, skipping Windows CE.  The NetBSD boot-
     loader, hpcboot(8), is provided as a Windows CE application program
     instead.  Though the bootloader is an application program, it blows the
     entire running Windows CE, its data, and its settings away from RAM (but
     not ROM!) when the kernel boots successfully.  If NetBSD is halted the
     machine will go through the cold reset and will reboot into Windows CE.

   Normal Operation
     Please, refer to the hpcboot(8) manual page.

BUGS

     There is no general way to launch the bootloader automatically, as only a
     few Windows CE machines provide an ``auto run'' mechanism.
