.Dd April 3, 2004 .Dt BOOT 8 hpcsh .Os .Sh NAME .Nm boot .Nd system bootstrapping procedures .Sh DESCRIPTION Windows CE machines with .Tn SuperH CPUs use the .Xr hpcboot 8 program to boot .Nx . Once running, .Nx can reboot itself if .Xr kloader 4 is configured in the kernel. .Ss Power fail and crash recovery
Unfortunately, .Nx 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 .Nx manually using .Xr hpcboot 8 .
p
Once
.Nx
starts, an automatic consistency check of the file systems will be
performed, and unless this fails, the system will resume multi-user
operations.
.Ss 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.
p
You can't boot
.Nx
directly, skipping Windows CE.
The
.Nx
bootloader,
.Xr 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
.Nx
is halted the machine will go through the cold reset and will reboot
into Windows CE.
.Ss Normal Operation
Please, refer to the
.Xr hpcboot 8
manual page.

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