hpcboot
—
load and boot kernel from Windows CE
hpcboot
is a program that runs on Windows CE. It
loads and executes the specified NetBSD kernel.
hpcboot
supports hpcarm, hpcmips, and hpcsh ports.
Click on the “Boot” button to start the boot process
with selected options. Click on the “Cancel” button to exit
hpcboot
.
“Ss Kernel” Ss Tab
On this tab you can select the kernel to boot and options to pass to the kernel.
- Directory
- In this combobox you specify the “current” directory. The
kernel and miniroot image pathnames are taken to be relative to this
directory.
hpcboot
can load kernel and miniroot
from FAT and UFS filesystems, and via HTTP.
- Kernel
- In this text field you specify the name of the kernel to load. Kernels
compressed with gzip(1) are
supported.
- Model
- Select your H/PC model in this combobox.
- Root File System
- This group of controls lets you specify the desired root file system type.
You can select wd(4),
sd(4),
md(4), and NFS root.
If you select md(4)
memory disk root file system, you should specify the path name of the
file system image in the text field below. Miniroot images compressed
with gzip(1) are
supported.
- Kernel Boot Flags
- This group of controls is used to pass boot flags to the kernel.
“Ss Option” Ss Tab
On this tab you can specify miscellaneous options that mostly control the
hpcboot
program itself.
- Auto Boot
- If this option is selected
hpcboot
will
automatically boot NetBSD after the specified
timeout.
- Reverse Video
- Tells kernel if it should use the framebuffer in reverse video mode.
- Pause Before Boot
- If selected, a warning dialog will be presented before
anything is done, right after the “Boot” button is
pressed.
- Load Debug Info
- This option currently does nothing.
- Safety Message
- If selected, a warning dialog will be presented after
the kernel has been loaded and prepared to be started. This will be your
last chance to cancel the boot.
- Extra Kernel Options
- In this text field you can specify additional options to pass to the
kernel.
“Ss Console” Ss Tab
This tab gets its name from the big text area that
hpcboot
uses as the “console” to report
its progress.
- Save To File
- If checked, the progress log will be sent to the specified file
instead.
- “Checkboxes Anonymous”
- The row of 8 checkboxes controls debugging options for
hpcboot
itself. They control the bits of an
internal variable, the leftmost checkbox being the 7th bit.
- “Buttons Anonymous”
- The buttons “a” to “d” control 4
“hooks” a developer might want to use during
hpcboot
development.
The hpcboot
utility first appeared in
NetBSD 1.6.
hpcboot
reads the entire kernel image at once, and
requires enough free area on the main memory.
