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.
