.Ss2 Prepare the NFS or TFTP server
|
|
.
|
|
Set up an NFS server and copy the install kernel renamed into
|
|
.Pa netbsd
|
|
to its root partition. Optionally copy the kernel into your TFTP directory
|
|
and make sure the
|
|
.Pa tftpd
|
|
service is running.
|
|
.
|
|
.Ss2 The altboot bootloader
|
|
The
|
|
.Pa altboot.bin
|
|
binary file loads a
|
|
.Nx
|
|
kernel from the root partition of a local disk, from TFTP or from NFS.
|
|
This bootloader binary should be made available by one of the following
|
|
methods (depending on the firmware):
|
|
.(bullet -compact
|
|
TFTP server
|
|
.It
|
|
NFS server
|
|
.It
|
|
Serial line upload
|
|
.It
|
|
Flash ROM
|
|
.bullet)
|
|
.Pp
|
|
When your firmware is restricted to
|
|
.Pa bootm
|
|
as the only command to run a program you should use
|
|
.Pa altboot.img
|
|
, which fakes a Linux kernel module.
|
|
.
|
|
.Ss2 Booting the installer
|
|
Depending on whether the serial console is attached to the first or the
|
|
second UART you will have to boot
|
|
.Pa netbsd-INSTALL
|
|
(1st UART at 0x4500)
|
|
or
|
|
.Pa netbsd-INSTALL_KURO
|
|
(2nd UART at 0x4600).
|
|
KuroBox and LinkStation systems are known to have the console on the
|
|
second UART.
|
|
.Pp
|
|
In most cases your NAS will run
|
|
.Tn "PPCBoot"
|
|
or
|
|
.Tn "U-Boot"
|
|
as firmware. You can access its command line via the serial adapter cable.
|
|
When auto-booting is enabled this will usually require to press a key
|
|
quickly after the system was switched on.
|
|
Then load the
|
|
.Pa altboot.bin
|
|
file into memory at
|
|
.Pa 0x1000000
|
|
and boot the installation kernel with
|
|
.Pp
|
|
.Dl > Ic "go 0x1000000 tftp:"
|
|
.Pp
|
|
for TFTP, or with
|
|
.Pp
|
|
.Dl > Ic "go 0x1000000 nfs:"
|
|
.Pp
|
|
when the kernel resides on NFS.
|
|
.Pp
|
|
Note, that when using
|
|
.Pa altboot.img
|
|
with
|
|
.Pa bootm
|
|
instead of
|
|
.Pa altboot.bin
|
|
you have to pass arguments like
|
|
.Pa tftp:
|
|
or
|
|
.Pa nfs:
|
|
in the
|
|
.Pa bootargs
|
|
enviroment variable.
|
|
.Pp
|
|
The installation kernel will run
|
|
.Pa sysinst
|
|
from an internal memory disk image.
|
|
.
|
|
.so ../common/sysinst
|
