# NAME

loadbsd — load and boot NetBSD/x68k kernel from Human68k

# SYNOPSIS

loadbsd.x | [-hvV] [-abDs] [-r root_device] kernel_file

# DESCRIPTION

loadbsd is a program runs on Human68k. It loads and executes the specified NetBSD/x68k kernel.

The options (for loadbsd itself) are as follows:

-h
  Show help and exit.
-v
  Enable verbose mode.
-V
  Print version of loadbsd and exit.

The options for NetBSD kernel are as follows:

-a
  Auto (multi-user) boot. This disables -s flag.
-b
  Ask boot device during boot. Pass RB_ASKNAME boot flag to the kernel.
-d
  Use compiled-in rootdev. Pass RB_DFLTROOT boot flag to the kernel.
-D
  Enter kernel debugger. Pass RB_KDB boot flag to the kernel.
-r root_device
  Specify boot device, which shall be mounted as root device. The default device is ‘`sd@0,0:a`'. Note that the boot device name is not the same as that of NetBSD. See BOOT DEVICE NAMES below.
-s
  Single user boot. Pass RB_SINGLE boot flag to the kernel. This disables -a flag. This flag is set by default.

Although listed separately, the options may be in any order.

# BOOT DEVICE NAMES

The format of boot device names is:

> `[/interface/]dev@unit[,lun][:partition]`

interface
  SCSI interface type. One of: ‘`spc@0`', ‘`spc@1`', ‘`mha@0`'. If the dev is a SCSI device, and interface is omitted, the current boot interface is used.
dev
  Device type. One of: ‘`fd`' (floppy disk drive), ‘`sd`' (SCSI disk), ‘`cd`' (SCSI CD-ROM), ‘`md`' (Memory disk).
unit
  Device unit #. You must specify the target SCSI ID if dev is a SCSI device.
lun
  SCSI LUN #. 0 is assumed if omitted.
partition
  Partition letter of device. Partition ‘`a`' is used if omitted.

# HISTORY

The loadbsd utility first appeared in NetBSD 1.4.

# BUGS

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