HPCBOOT(8)

NAME
hpcboot - load and boot kernel from Windows CE

SYNOPSIS
hpcboot.exe

DESCRIPTION
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.

  Kernel 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.

  Option 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.

  Console 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.

HISTORY
The hpcboot utility first appeared in NetBSD 1.6.

BUGS
hpcboot reads the entire kernel image at once, and requires enough free area on the main memory.
