HPCBOOT(8) BSD System Manager's Manual 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 direc-
tory.
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.
SEE ALSO kloader(4), boot(8)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.

BOOT(8) BSD System Manager's Manual BOOT(8)NAME
boot -- system bootstrapping procedures
DESCRIPTION
This document provides information on using common features in the NetBSD boot loader. Additional information may be found in architecture-
specific boot(8) manual pages.
In the native NetBSD boot protocol, options are passed from the boot loader to the kernel via flag bits in the boothowto variable (see
boothowto(9)).
Interactive mode
In interactive mode, the boot loader will present a prompt, allowing input of these commands:
boot [device:] [filename] [-1234abcdmqsvxz]
The default device will be set to the disk that the boot loader was loaded from. To boot from an alternate disk, the full name of
the device should be given at the prompt. device is of the form xd [N[x]] where xd is the device from which to boot, N is the unit
number, and x is the partition letter.
The following list of supported devices may vary from installation to installation:
hd Hard disks.
fd Floppy drives.
The default filename is netbsd; if the boot loader fails to successfully open that image, it then tries netbsd.gz (expected to be a
kernel image compressed by gzip), followed by netbsd.old, netbsd.old.gz, onetbsd, and finally onetbsd.gz. Alternate system images
can be loaded by just specifying the name of the image.
Options are:
-1 Sets the machine-dependent flag RB_MD1 in boothowto.
-2 Sets the machine-dependent flag RB_MD2 in boothowto.
-3 Sets the machine-dependent flag RB_MD3 in boothowto.
-4 Sets the machine-dependent flag RB_MD4 in boothowto.
-a Sets the RB_ASKNAME flag in boothowto. This causes the kernel to prompt for the root file system device, the system crash
dump device, and the path to init(8).
-b Sets the RB_HALT flag in boothowto. This causes subsequent reboot attempts to halt instead of rebooting.
-c Sets the RB_USERCONF flag in boothowto. This causes the kernel to enter the userconf(4) device configuration manager as soon
as possible during the boot. userconf(4) allows devices to be enabled or disabled, and allows device locators (such as hard-
ware addresses or bus numbers) to be modified before the kernel attempts to attach the devices.
-d Sets the RB_KDB flag in boothowto. Requests the kernel to enter debug mode, in which it waits for a connection from a kernel
debugger; see ddb(4).
-m Sets the RB_MINIROOT flag in boothowto. Informs the kernel that a mini-root file system is present in memory.
-q Sets the AB_QUIET flag in boothowto. Boot the system in quiet mode.
-s Sets the RB_SINGLE flag in boothowto. Boot the system in single-user mode.
-v Sets the AB_VERBOSE flag in boothowto. Boot the system in verbose mode.
-x Sets the AB_DEBUG flag in boothowto. Boot the system with debug messages enabled.
-z Sets the AB_SILENT flag in boothowto. Boot the system in silent mode.
consdev dev
Immediately switch the console to the specified device dev and reprint the banner. dev must be one of pc, com0, com1, com2, com3,
com0kbd, com1kbd, com2kbd, com3kbd, or auto. See Console Selection Policy in boot_console(8).
dev [device]
Set the default drive and partition for subsequent filesystem operations. Without an argument, print the current setting. device
is of the form specified in boot.
help Print an overview about commands and arguments.
ls [path]
Print a directory listing of path, containing inode number, filename, and file type. path can contain a device specification.
quit Reboot the system.
In an emergency, the bootstrap methods described in the NetBSD installation notes for the specific architecture can be used.
FILES
/boot boot program code loaded by the primary bootstrap
/netbsd system code
/netbsd.gz gzip-compressed system code
/usr/mdec/boot master copy of the boot program (copy to /boot)
/usr/mdec/bootxx_fstype primary bootstrap for filesystem type fstype, copied to the start of the NetBSD partition by installboot(8).

The kernel file name must be specified before, not after, the boot options. Any filename specified after the boot options, e.g.:
boot -d netbsd.test
is ignored, and the default kernel is booted.
